该方法采用反对称双正交小波分解系数计算视频帧的方向梯度向量，再统计由梯度向量角和模值构成的联合空间二维直方图，然后计算连续帧直方图之间的距离，得到两帧之间的不连续值，最后采用自适应阈值分割，检测出镜头边界。-This method is the use of anti-symmetric biorthogonal wavelet decomposition coefficients video frame the direction of gradient vector, and then statistics from the gradient vector angle and modulus values constitute the joint space of two-dimensional histogram, and then calculating the histogram for the distance between frames, by the two frames between the consecutive values, the final adaptive threshold segmentation, shot boundary detected.
