Automatic determination of a region of influence

Abstract:

Embodiments are directed toward systems and methods segment an input image for performance of a warp kernel that executes by a graphics processing unit (GPU) the warp kernel on an array of dummy data, wherein cells of the array are populated with data representing the cells' respective locations within the array, determine, from an output array obtained from execution of the warp kernel on the dummy data, a segmentation size, and build by the GPU an output image from the input image by executing the warp kernel on the input image according to the segmentation size.
