Abstract
A selection module for selecting an intra mode comprises a histogram of oriented gradient (HOG) module, for receiving a coding unit (CU), to select four angular modes from 33 angular modes of the CU, a DC mode of the CU and a planar mode of the CU; and a decision module, couple to the HOG module, for receiving the six modes from the HOG module, to compare the six modes according to a Split Sum of Absolute Transformed Difference (SSATD) algorithm, to select one of the six modes.
