CPC Code(s): G06T3/40
Abstract: aspects of the present disclosure are directed to applying encoding techniques for non-linear visual data sampling. visual data, such as an image or texture, can be sampled, for example to determine color values at different points of the visual data. some visual data includes discontinuous content (e.g., a stark color boundary). conventional sampling techniques (e.g., linear filtering) rely on averaging when calculating color values for sampled points of visual data. such averaging can deteriorate the integrity of a stark color boundary, and thus this conventional sampling often performs poorly when used to sample visual data with discontinuous content. implementations generate encodings for visual data comprising discontinuous content that can be effectively sampled. for example, an encoding manager can store the visual data according to an encoding scheme that can be sampled for improved color selection performance using one or more encoding specific sampling techniques.
