| 摘 要： | 镜头边界检测是进行视频内容分析的首要步骤。提出一种基于相邻尺度小波变换乘积的镜头边缘检测方法。对镜头内的每帧视频图像进行小波变换，求出各帧图像相邻尺度小波变换尺度积的模和方向。计算连续帧图像尺度积与模之间的绝对距离，得到2帧图像间的不连续值。通过自适应阈值分割，检测出镜头边界。

| Abstract: | Shot boundary detection is the chiefly step of video content analysis. This paper proposes a method of shot boundary detection based on the product of adjacent scale wavelet transform. Each video frame image in the shot is carried on wavelet transform. The modulus and direction of adjacent scale wavelet transform scale product of every frame image are obtained. It calculates absolute distance among consecutive frames image scale plot and modulus, and gets discrete value between two frame images. The shot boundary is detected by using adaptive threshold segmentation. |
