Description
In many image processing problems, we need to process polygons that usually involve rasterization. Also, in many such problems we need to compute reductions over images, such as average of intensities or other metrics. In some cases, a combination of the two computations is desired: we need to use the area of polygons to restrict which pixels should contribute to a reduction operation. Doing this in two steps, first computing a mask and then using it in a reduction is expected to be inefficient. We look into the problem of how to efficiently perform these two operations in a single step on the GPU exploiting parallelism on multiple levels.
