象素块 meaning in English

pixel block

With the complexity decrease of integer pixel accuracy motion estimation , the complexity of sub pixel accuracy motion estimation is comparative to that of integer pixel accuracy motion estimation , so the research of fast sub pixel accuracy motion estimation algorithms is rising . a fast half pixel accuracy motion estimation algorithms based on mathematical prediction models is proposed in this paper
随着整象素级运动估计复杂度的降低，亚象素级运动估计的复杂度显得和整象素级运动估计复杂度相当，快速亚象素运动估计算法的研究正在兴起，本文介绍了提出的基于数学模型预测的快速半象素块匹配算法。
