Abstract: Apparatus and method for denoising of images generated by a rendering engine such as a ray tracing engine. For example, one embodiment of a system or apparatus comprises: A system comprising: a plurality of nodes to perform ray tracing operations; a dispatcher node to dispatch graphics work to the plurality of nodes, each node to perform ray tracing to render a region of an image frame; at least a first node of the plurality comprising: a ray-tracing renderer to perform ray tracing to render a first region of the image frame; and a denoiser to perform denoising of the first region using a combination of data associated with the first region and data associated with a region outside of the first region, at least some of the data associated with the region outside of the first region to be retrieved from at least one other node.

Abstract: Apparatus and method for validation of complex perceptional systems with efficient simulation of optical variants. For example one embodiment of a method comprises: identifying foreground objects having a layered object representation in a scene, the layered object representation including surface properties, the scene comprising a sequence of images to be used in a simulation for testing an autonomous driving (AD) system; incrementally rendering one or more images in the sequence of images by performing the operations of: using a previously-rendered image with foreground objects removed as a starting point for rendering a current image; rendering the foreground objects of the current image based on the layered representations; and rendering regions outside of the foreground objects which are influenced by the foreground objects based on the layered representations.

Abstract: Apparatus and method for non-local means filtering using a media processing block of a graphics processor. For example, one embodiment of a processor comprises: ray tracing circuitry to execute a first set of one or more commands to traverse rays through a bounding volume hierarchy (BVH) to identify BVH nodes and/or primitives intersected by the ray; shader execution circuitry to execute one or more shaders responsive to a second set of one or more commands to render a sequence of image frames based on the BVH nodes and/or primitives intersected by the ray; and a media processor comprising motion estimation circuitry to execute a third set of one or more commands to perform non-local means filtering to remove noise from the sequence of image frames based on a mean pixel value collected across the sequence of image frames.
