Adaptive rendering with linear predictions

A non-transitory computer-readable medium containing computer program code that, when executed by operation of one or more computer processors, performs an operation for rendering an image, the operation comprising:

• selecting a plurality of positions within the image;
• constructing a respective linear prediction model for each selected position, wherein a respective prediction window is determined for each constructed linear prediction model;
• and
• rendering the image using the constructed linear prediction models to predict values for each of a plurality of pixels of the image, wherein at least one of the constructed linear prediction models is used to predict values for two or more of the plurality of pixels of the image, and wherein a value for at least one of the plurality of pixels is determined based on two or more of the constructed linear prediction models.

A system, comprising:

• one or more computer processors;
• and
• a non-transitory memory containing computer program code that, when executed by operation of the one or more computer processors, performs an operation for rendering an image, the operation comprising:
• selecting a plurality of positions within the image;
• constructing a respective linear prediction model for each selected position, wherein a respective prediction window is determined for each constructed linear prediction model;
• and
• rendering the image using the constructed linear prediction models to predict values for each of a plurality of pixels of the image, wherein at least one of the constructed linear prediction models is used to predict values for two or more of the plurality of pixels of the image, and wherein a value for at least one of the plurality of pixels is determined based on two or more of the constructed linear prediction models.
