ABSTRACT:
A system and method are provided to reduce noise in computer generated images. A source object is stochastically sampled to generate a frame image which appears in motion through multiple successive frames. The motion of the frame image is predicted and the samples taken at the predicted location in various projected frames are used to generate an improved, antialiased, noise-reduced image in a single reference frame. By using stochastically obtained samples from multiple frames, the noise reduction technique provides many additional samples without any additional cost of creating them.
