Abstract
Systems and techniques are described for processing video data. For example, an apparatus can determine, for a sample of a first block of video data, histogram of gradient (HoG) information based on at least one sample from a second block neighboring the first block. The apparatus can determine, based on the HoG information, an angle associated with a direction of a gradient for the sample and the at least one sample from the second block neighboring the first block. The apparatus can further compare the angle to one or more predefined values and determine an index associated with the angle based on the comparison of the angle to the one or more predefined values. The apparatus can then determine, based on the index, an intra-prediction mode for coding the first block of video data.
