摘要：
A new block-matching algorithm for fast motion estimation is proposed. The so-called Star Diamond Search with Adaptive Threshold (SDth) 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 SDth algorithm has been implemented and tested using several video sequences. SDth algorithm is also compared with previous search methods to demonstrate its utility.
