 *  @ingroup nppi
 *
 * Routines manipulating an image geometry.
 *
 * These functions can be found in the nppig library. Linking to only the sub-libraries that you use can significantly
 * save link time, application load time, and CUDA runtime startup time when using dynamic libraries.
 *
 * \section geometric_transform_api Geometric Transform API Specifics
 *
 * This section covers some of the unique API features common to the
 * geometric transform primitives.
 *
 * \section geometric_transform_roi Geometric Transforms and ROIs
 *
 * Geometric transforms operate on source and destination ROIs. The way
 * these ROIs affect the processing of pixels differs from other (non
 * geometric) image-processing primitives: Only pixels in the intersection
 * of the destination ROI and the transformed source ROI are being
 * processed.
 *
 * The typical processing proceedes as follows:
 * -# Transform the rectangular source ROI (given in source image coordinates)
 *      into the destination image space. This yields a quadrilateral.
 * -# Write only pixels in the intersection of the transformed source ROI and
 *      the destination ROI.
 *
 * \section geometric_transforms_interpolation Pixel Interpolation
 *
 * The majority of image geometry transform operation need to perform a 
 * resampling of the source image as source and destination pixels are not
 * coincident.
 *
 * NPP supports the following pixel inerpolation modes (in order from fastest to 
 * slowest and lowest to highest quality):
 * - nearest neighbor
 * - linear interpolation
 * - cubic convolution
 * - supersampling
 * - interpolation using Lanczos window function
 *
 * \section resize_error_codes Resize Error Codes
 * \subsection resize_error_codes Resize Error Codes
 * The resize primitives return the following error codes:
 *
 *         - NPP_WRONG_INTERSECTION_ROI_ERROR indicates an error condition if
 *           srcROIRect has no intersection with the source image.
 *         - NPP_RESIZE_NO_OPERATION_ERROR if either destination ROI width or
 *           height is less than 1 pixel.
 *         - NPP_RESIZE_FACTOR_ERROR Indicates an error condition if either nXFactor or
 *           nYFactor is less than or equal to zero or in the case of NPPI_INTER_SUPER are not both downscaling.
 *         - NPP_INTERPOLATION_ERROR if eInterpolation has an illegal value.
 *         - NPP_SIZE_ERROR if source size width or height is less than 2 pixels.
 *         - NPP_RECTANGLE_ERROR if either destination ROI width or
 *           height is less than 1 pixel.

/** 
 *  \section image_resize_square_pixel ResizeSqrPixel
 *  @defgroup image_resize_square_pixel ResizeSqrPixel
 *
 * ResizeSqrPixel functions attempt to choose source pixels that would approximately represent the center of the destination pixels.
 * It does so by using the following scaling formula to select source pixels for interpolation:
 *
 * \code
 *   nAdjustedXFactor = 1.0 / nXFactor;
 *   nAdjustedYFactor = 1.0 / nYFactor;
 *   nAdjustedXShift = nXShift * nAdjustedXFactor + ((1.0 - nAdjustedXFactor) * 0.5);
 *   nAdjustedYShift = nYShift * nAdjustedYFactor + ((1.0 - nAdjustedYFactor) * 0.5);
 *   nSrcX = nAdjustedXFactor * nDstX - nAdjustedXShift;
 *   nSrcY = nAdjustedYFactor * nDstY - nAdjustedYShift;
 * \endcode
 *
 * ResizeSqrPixel functions support the following interpolation modes:
 *
 * \code
 *   NPPI_INTER_NN
 *   NPPI_INTER_LINEAR
 *   NPPI_INTER_CUBIC
 *   NPPI_INTER_CUBIC2P_BSPLINE
 *   NPPI_INTER_CUBIC2P_CATMULLROM
 *   NPPI_INTER_CUBIC2P_B05C03
 *   NPPI_INTER_SUPER
 *   NPPI_INTER_LANCZOS
 * \endcode
 *
 * In the ResizeSqrPixel functions below source image clip checking is handled as follows:
 *
 * If the source pixel fractional x and y coordinates are greater than or equal to oSizeROI.x and less than oSizeROI.x + oSizeROI.width and
 * greater than or equal to oSizeROI.y and less than oSizeROI.y + oSizeROI.height then the source pixel is considered to be within
 * the source image clip rectangle and the source image is sampled.  Otherwise the source image is not sampled and a destination pixel is not
 * written to the destination image.

 *  @defgroup image_resize_batch ResizeBatch
 *  
 *  
 * Above is the diagram of batch resize functions for variable ROIs. Figure shows the flexibility that the API can handle.
 * The ROIs for source and destination images can be any rectangular width and height that reflects the needed resize factors, inside or beyond the image boundary.
 *
 * ResizeBatch functions use scale factor automatically determined by the width and height ratios for each pair of input / output images in provided batches.
 *
 * In this function as in nppiResize the resize scale factor is automatically determined by the width and height ratios of oSrcRectROI and oDstRectROI.  If either of those 
 * parameters intersect their respective image sizes then pixels outside the image size width and height will not be processed.
 * Details of the resize operation are described above in the Resize section. ResizeBatch generally takes the same parameter list as 
 * Resize except that there is a list of N instances of those parameters (N > 1) and that list is passed in device memory. A convenient
 * data structure is provided that allows for easy initialization of the parameter lists.  The only restriction on these functions is
 * that there is one single source ROI rectangle and one single destination ROI rectangle which are applied respectively to each image 
 * in the batch.  The primary purpose of this function is to provide improved performance for batches of smaller images as long as GPU 
 * resources are available.  Therefore it is recommended that the function not be used for very large images as there may not be resources 
 * available for processing several large images simultaneously.  
 * A single set of oSrcRectROI and oDstRectROI values are applied to each source image and destination image in the batch in the nppiResizeBatch 
 * version of the function while per image specific oSrcRectROI and oDstRectROI values can be used in the nppiResizeBatch_Advanced version of the function.
 * Source and destination image sizes may vary but oSmallestSrcSize and oSmallestDstSize must be set to the smallest
 * source and destination image sizes in the batch. The parameters in the NppiResizeBatchCXR structure represent the corresponding
 * per-image nppiResize parameters for each image in the nppiResizeBatch functions and the NppiImageDescriptor and NppiResizeBatchROI_Advanced structures represent 
 * the corresponding per-image nppiResize parameters for the nppiResizeBatch_Advanced functions.  The NppiResizeBatchCXR or 
 * NppiImageDescriptor and NppiResizeBatchROI_Advanced arrays must be in device memory.
 *
 * ResizeBatch supports the following interpolation modes:
 *
 * \code
 *   NPPI_INTER_NN
 *   NPPI_INTER_LINEAR
 *   NPPI_INTER_CUBIC
 *   NPPI_INTER_SUPER
 * \endcode
 *
 * The resize primitives return the following error codes: \ref resize_error_codes.
 *

 *
 * \param oSmallestSrcSize Size in pixels of the entire smallest source image width and height, may be from different images.

 * \param oSmallestDstSize Size in pixels of the entire smallest destination image width and height, may be from different images.
 * \param oDstRectROI Region of interest in the destination images (may overlap destination image size width and height).
 * \param eInterpolation The type of eInterpolation to perform resampling. Currently limited to NPPI_INTER_NN, NPPI_INTER_LINEAR, NPPI_INTER_CUBIC, or NPPI_INTER_SUPER.

 * \section image_remap Remap
 * @defgroup image_remap Remap
 *
 * Routines providing remap functionality.
 *
 * Remap supports the following interpolation modes:
 *
 *   NPPI_INTER_NN
 *   NPPI_INTER_LINEAR
 *   NPPI_INTER_CUBIC
 *   NPPI_INTER_CUBIC2P_BSPLINE
 *   NPPI_INTER_CUBIC2P_CATMULLROM
 *   NPPI_INTER_CUBIC2P_B05C03
 *   NPPI_INTER_LANCZOS
 *
 * Remap chooses source pixels using pixel coordinates explicitely supplied in two 2D device memory image arrays pointed to by the pXMap and pYMap pointers.
 * The pXMap array contains the X coordinated and the pYMap array contains the Y coordinate of the corresponding source image pixel to
 * use as input. These coordinates are in floating point format so fraction pixel positions can be used. The coordinates of the source
 * pixel to sample are determined as follows:
 *
 *   nSrcX = pxMap[nDstX, nDstY]
 *   nSrcY = pyMap[nDstX, nDstY]
 *
 * In the Remap functions below source image clip checking is handled as follows:
 *
 * If the source pixel fractional x and y coordinates are greater than or equal to oSizeROI.x and less than oSizeROI.x + oSizeROI.width and
 * greater than or equal to oSizeROI.y and less than oSizeROI.y + oSizeROI.height then the source pixel is considered to be within
 * the source image clip rectangle and the source image is sampled.  Otherwise the source image is not sampled and a destination pixel is not
 * written to the destination image. 
 *
 * \section remap_error_codes Error Codes
 * The remap primitives return the following error codes:
 *
 *         - NPP_WRONG_INTERSECTION_ROI_ERROR indicates an error condition if
 *           srcROIRect has no intersection with the source image.
 *         - NPP_INTERPOLATION_ERROR if eInterpolation has an illegal value.

 *
 * Details of the warp affine operation are described above in the WarpAffine section. WarpAffineBatch generally takes the same parameter list as 
 * WarpAffine except that there is a list of N instances of those parameters (N > 1) and that list is passed in device memory. A convenient
 * data structure is provided that allows for easy initialization of the parameter lists.  The aTransformedCoeffs array is for internal use only
 * and should not be directly initialized by the application.  The only restriction on these functions is
 * that there is one single source ROI rectangle and one single destination ROI rectangle which are applied respectively to each image 
 * in the batch.  The primary purpose of this function is to provide improved performance for batches of smaller images as long as GPU 
 * resources are available.  Therefore it is recommended that the function not be used for very large images as there may not be resources 
 * available for processing several large images simultaneously.  
 * A single set of oSrcRectROI and oDstRectROI values are applied to each source image and destination image in the batch.
 * Source and destination image sizes may vary but oSmallestSrcSize must be set to the smallest
 * source and image size in the batch. The parameters in the NppiWarpAffineBatchCXR structure represent the corresponding
 * per-image nppiWarpAffine parameters for each image in the batch.  The NppiWarpAffineBatchCXR array must be in device memory.
 * The nppiWarpAffineBatchInit function MUST be called AFTER the application has initialized the array of NppiWarpAffineBatchCXR structures
 * and BEFORE calling any of the nppiWarpAffineBatch functions to so that the aTransformedCoeffs array can be internally pre-initialized
 * for each image in the batch. The batch size passed to nppiWarpAffineBatchInit must match the batch size passed to the corresponding
 * warp affine batch function.
 *
 *
 * WarpAffineBatch supports the following interpolation modes:
 *
 * \code
 *   NPPI_INTER_NN
 *   NPPI_INTER_LINEAR
 *   NPPI_INTER_CUBIC

 *         - NPP_RECTANGLE_ERROR if either destination ROI width or
 *           height is less than 1 pixel.
 *         - NPP_INTERPOLATION_ERROR if eInterpolation has an illegal value.
 *         - NPP_SIZE_ERROR if source size width or height is less than 2 pixels.
 *

 * @defgroup backwards_affine_transform Backwards Affine Transform
 * Transforms (warps) an image based on an affine transform. 
 *
 * The affine transform is given as a \f$2\times 3\f$ matrix C. A pixel location \f$(x, y)\f$ in the
 * source image is mapped to the location \f$(x', y')\f$ in the destination image.
 * The destination image coorodinates fullfil the following properties:
 * \f[
 * x = c_{00} * x' + c_{01} * y' + c_{02} \qquad
 * y = c_{10} * x' + c_{11} * y' + c_{12} \qquad
 * C = \left[ \matrix{c_{00} & c_{01} & c_{02} \cr 
                      c_{10} & c_{11} & c_{12} } \right]
 * \f]
 * In other words, given matrix \f$C\f$ the source image's shape is transfored to the destination image
 * using the inverse matrix \f$C^{-1}\f$:
 * \f[
 * M = C^{-1} = \left[ \matrix{m_{00} & m_{01} & m_{02} \cr 
                               m_{10} & m_{11} & m_{12} } \right]

 * Transforms (warps) an image based on an affine transform. 
 *
 * The affine transform is computed such that it maps a quadrilateral in source image space to a 
 * quadrilateral in destination image space. 
 *
 * An affine transform is fully determined by the mapping of 3 discrete points.
 * The following primitives compute an affine transformation matrix that maps 
 * the first three corners of the source quad are mapped to the first three 
 * vertices of the destination image quad. If the fourth vertices do not match
 * the transform, an NPP_AFFINE_QUAD_INCORRECT_WARNING is returned by the primitive.

 * @defgroup perspective_transform_batch Perspective Transform Batch
 *
 * Details of the warp perspective operation are described above in the WarpPerspective section. WarpPerspectiveBatch generally takes the same parameter list as 
 * WarpPerspective except that there is a list of N instances of those parameters (N > 1) and that list is passed in device memory. A convenient
 * data structure is provided that allows for easy initialization of the parameter lists.  The aTransformedCoeffs array is for internal use only
 * and should not be directly initialized by the application.  The only restriction on these functions is
 * that there is one single source ROI rectangle and one single destination ROI rectangle which are applied respectively to each image 
 * in the batch.  The primary purpose of this function is to provide improved performance for batches of smaller images as long as GPU 
 * resources are available.  Therefore it is recommended that the function not be used for very large images as there may not be resources 
 * available for processing several large images simultaneously.  
 * A single set of oSrcRectROI and oDstRectROI values are applied to each source image and destination image in the batch.
 * Source and destination image sizes may vary but oSmallestSrcSize must be set to the smallest
 * source and image size in the batch. The parameters in the NppiWarpPerspectiveBatchCXR structure represent the corresponding
 * per-image nppiWarpPerspective parameters for each image in the batch.  The NppiWarpPerspectiveBatchCXR array must be in device memory.
 * The nppiWarpPerspectiveBatchInit function MUST be called AFTER the application has initialized the array of NppiWarpPerspectiveBatchCXR structures
 * and BEFORE calling any of the nppiWarpPerspectiveBatch functions to so that the aTransformedCoeffs array can be internally pre-initialized
 * for each image in the batch. The batch size passed to nppiWarpPerspectiveBatchInit must match the batch size passed to the corresponding
 * warp perspective batch function.
 *
 *
 * WarpPerspectiveBatch supports the following interpolation modes:
 *
 * \code
 *   NPPI_INTER_NN
 *   NPPI_INTER_LINEAR
 *   NPPI_INTER_CUBIC
 * \endcode
 *
 * \subsection CommonWarpPerspectiveBatchParameters Common parameters for nppiWarpPerspectiveBatch functions:
 *
 * \param oSmallestSrcSize Size in pixels of the entire smallest source image width and height, may be from different images.
 * \param oSrcRectROI Region of interest in the source images.
 * \param oDstRectROI Region of interest in the destination images.
 * \param eInterpolation The type of eInterpolation to perform resampling. Currently limited to NPPI_INTER_NN, NPPI_INTER_LINEAR, or NPPI_INTER_CUBIC. 
 * \param pBatchList Device memory pointer to nBatchSize list of NppiWarpPerspectiveBatchCXR structures.
 * \param nBatchSize Number of NppiWarpPerspectiveBatchCXR structures in this call (must be > 1).
 * \param nppStreamCtx \ref application_managed_stream_context.

 * @defgroup backwards_perspective_transform Backwards Perspective Transform
 * Transforms (warps) an image based on a perspective transform. 
 *
 * The perspective transform is given as a \f$3\times 3\f$ matrix C. A pixel location \f$(x, y)\f$ in the
 * source image is mapped to the location \f$(x', y')\f$ in the destination image.
 * The destination image coorodinates fullfil the following properties:
 * \f[
 * x = \frac{c_{00} * x' + c_{01} * y' + c_{02}}{c_{20} * x' + c_{21} * y' + c_{22}} \qquad
 * y = \frac{c_{10} * x' + c_{11} * y' + c_{12}}{c_{20} * x' + c_{21} * y' + c_{22}}
 * \f]
 * \f[
 * C = \left[ \matrix{c_{00} & c_{01} & c_{02}   \cr

                      c_{20} & c_{21} & c_{22} } \right]
 * \f]
 * In other words, given matrix \f$C\f$ the source image's shape is transfored to the destination image
 * using the inverse matrix \f$C^{-1}\f$:
 * \f[
 * M = C^{-1} = \left[ \matrix{m_{00} & m_{01} & m_{02} \cr 
                               m_{10} & m_{11} & m_{12} \cr 
                               m_{20} & m_{21} & m_{22} } \right]
 * x' = \frac{c_{00} * x + c_{01} * y + c_{02}}{c_{20} * x + c_{21} * y + c_{22}} \qquad
 * y' = \frac{c_{10} * x + c_{11} * y + c_{12}}{c_{20} * x + c_{21} * y + c_{22}}
