Abstract

A new block-matching algorithm for fast motion estimation is proposed. The so-called Star Diamond Search with Adaptive Threshold (SD_th) is two steps algorithm. Adaptive threshold for matching errors eliminates invalid blocks early from motion estimation procedure. Then it performs a search for final motion vector with a Star Diamond Algorithm. Proposed SD_th algorithm has been implemented and tested using several video sequences. SD_th algorithm is also compared with previous search methods to demonstrate its utility.
