用matlab实现从原始视频中提取关键帧，并且自动生成新视频，新视频只由关键帧组成从而实现视频总结。(Using matlab realize extracted from the original video key frame, and automatically generate a new video, new video key frame composed by only enabling the video summary.)

时频信号分析技术，双线性方法，Wigner-Ville分布的应用，可以得到高斯包络线性调频信号的WVD图(Time-frequency signal analysis, bilinear method, Wigner-Ville distribution application, you can get WVD FIG Gaussian envelope chirp signal)

说明：  对变量DMC源程序，matlab语言。可以看看。(DMC source of variable)

提出了一种离散小波变换域实现图像水印的方法。这种算法充分利用小波变换的特点,把原始图像及水印图像塔式分解,在多分辨率分解后的相同的频段来嵌入水印信息。该方法也利用了人眼视觉特性,算法简单而有效。实验证明,该算法较好地解决了水印不可见性与鲁棒性之间的矛盾,对常见的水印攻击都有较强的鲁棒性。(presents a discrete wavelet transform domain image watermarking method. This algorithm using wavelet transform characteristics, the original image and the watermark image tower decomposition, Multiresolution decomposition in the same frequency band to the embedded watermark. The method has also been used HVS, the algorithm is simple and effective. Experiments show that the algorithm can solve the watermark is visible with the robust nature of, common to have more attacks watermark robustness.)
