Equipment and methods for performing nonlocal average filtering using the motion estimation circuit of a graphics processor

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and a method for performing nonlocal average filtering using a media processing block of a graphics processor. A processor with a ray tracing circuit that traverses a ray through a bounding volume hierarchy (BVH) and executes one or more commands in a first set to identify a BVH node and / or primitive that intersects the ray. A shader execution circuit that executes one or more shaders in response to a second set of commands to render a series of image frames based on BVH nodes and / or primitives that intersect the ray. A motion estimation circuit that performs non-local average filtering to execute one or more commands in a third set to remove noise from a series of image frames based on the average pixel values collected over the series of image frames. Equipped with a media processor including. [Selection diagram] Fig. 1
