#include <opencv2/cudalegacy/NPP_staging.hpp>
Warp image using provided 2D vector field and 1x1 point spread function. 32-bit floating point image, single channel
During warping pixels from the source image may fall between pixels of the destination image. PSF (point spread function) describes how the source image pixel affects pixels of the destination. For 1x1 PSF only single pixel with the largest intersection is affected (similar to nearest interpolation).
Destination image size and line step must be the same as the source image size and line step

Warp image using provided 2D vector field and 2x2 point spread function. 32-bit floating point image, single channel
During warping pixels from the source image may fall between pixels of the destination image. PSF (point spread function) describes how the source image pixel affects pixels of the destination. For 2x2 PSF all four intersected pixels will be affected.
Destination image size and line step must be the same as the source image size and line step
