Abstract
Description
算法;基于摄像机运动的重放镜头相似度计算 输入:重放镜头和普通镜头的二元组序列C1={(c1[i],l1[i])}和C2={(c2[j],l2[j]), 长度分别为L1和L2。 输出:两个特征序列的相似度s (1)s=0; (2)while(C1 is not empty){ (3) s1=0; (4) for(d=-L1+1;d<L2;d++){ (5) s2=0; (6) for(i=0;i<L1;i++){ (7) j=i+d; (8) if(0<=j&&j<L2&&c1[i]==c2[j])) (9) s2=s2+min(l1[i],12[j])+score; (10) } (11) if(s2>s1)sl=s2; (12) } (13) if(s1>s)s=s1; (14) reduce(C1)//remove the shoxtest motion from C1 (15)} (16)return s;
