摘要: 本文提出了一種新的序列圖象編碼塊匹配準(zhǔn)則比特位相關(guān)匹配函數(shù)。在使用相同的快速搜索算法條件下,比特位相關(guān)匹配函數(shù)與均方誤差函數(shù)相比可獲得相當(dāng)?shù)奈灰乒乐稻?但它可使快速搜索算法的計(jì)算復(fù)雜度降低,并且便于并行實(shí)現(xiàn),從而有效地縮短了序列圖象編碼時(shí)間。

Abstract: This paper proposes a new block matching criterion called the bit-correlation matching function for sequence image coding. By using the same fast search algorithm, the bit-correlation matching function not only results in as nearly same a uracy in displacement estimation as mean square error function, but also makes the fast search algorithm low in computation complexity and easy to parallel operation, thus reducing the coding time of sequence image efficiently. -
