The keeper's note

A rendering technique that speeds up image synthesis by fitting local linear prediction models to pixel neighborhoods instead of full Monte Carlo sampling.

Abstract

Systems, methods and articles of manufacture for rendering an image. Embodiments include selecting a plurality of positions within the image and constructing a respective linear prediction model for each selected position. A respective prediction window is determined for each constructed linear prediction model. Additionally, embodiments render the image using the linear prediction models using the constructed linear prediction models, whereat least one of the constructed linear prediction models is used to predict values for two or more of a plurality of pixels of the image, and where a value for at least one of theplurality of pixels is determined based on two or more of the constructed linear prediction models.
