- SYSTEMS AND METHODS FOR LOW COMPLEXITY FORWARD TRANSFORMS USING MESH-BASED CALCULATIONS

摘要

Systems and methods for low complexity forward transformations using mesh-based computations are described herein. One aspect of the subject matter described in this disclosure provides a video encoder comprising a memory configured to store video information. The video encoder further includes a processor in communication with the memory. The processor is configured to decompose the transformation into a plurality of transformation stages. The processor is further configured to transform the video information using a plurality of stages to determine a transform stage output at each transform stage. The processor is further configured to limit the conversion stage output at each conversion stage to a predetermined bit depth. The processor is further configured to perform operations on a limited transformation output of the last stage of the plurality of stages, the operations being available for use with data having only a predetermined bit depth.;
