Abstract

Systems, methods, and instrumentalities are disclosed for transform set selection based on template cost analysis. For example, a device (e.g., a video encoding device and/or a video decoding device) may obtain at least one prediction sample. The device may obtain a histogram of gradient (HoG). The device may determine whether to perform a template cost analysis. Based on a determination to perform the template cost analysis, the device may obtain at least one intra mode candidate based on the HoG. The device may determine a respective template cost associated with at least one intra mode candidate. The device may reorder at least one intra mode candidate. The device may obtain at least one virtual intra prediction mode (VIPM). The device may obtain a transform set and obtain a transform kernel. The video decoding device may decode the current block, and the video encoding device may encode the current block.
