【摘要】 为了克服运动估计的传统快速块匹配算法容易陷入局部最优的缺点,本文提出了适合实时编码的改进免疫算法的块匹配运动估计算法,该算法结合菱形法,加入自适应搜索窗并改进部分算子,克服了原有免疫算法在个别抗体产生的新后代极易被相互抑制掉的缺点,保留更多的优秀个体,加快了收敛速度。更多还原

【Abstract】 To solve the problem of being trapped to local optimal,a novel method of motion estimation based on an improved immune algorithm is proposed,which fits the request of real time video coding.The DS search pattern and adaptive search window are also introduced into this method.Compared with the motion estimation based on immune algorithm before,this method overcomes the weakness that the offspring of some antibody are always restrained by each other,so it preserves more good individuals and improves the speed of convergence.更多还原
