Secondly algorithms for the detection of the video shot boundaries with complex editing and the discrimination of camera motion and gradual transition are presented. 提出了一种能够适应复杂镜头边界编辑效果的视频镜头分割算法和一种能够有效地区分镜头运动与渐变的方法。
Two-dimensional ( 2-D) multirate systems and filter banks ( FBs) have been used widely in image compression, video compression, digital communication, computer vision and texture discrimination and classification, etc. 二维(Two-dimensional,2-D)多速率系统和滤波器组理论已被广泛应用于图像压缩、视频压缩、数字通信、计算机视觉和纹理识别与分类等领域。
We extract video fingerprint based on the improved SIFT. The video fingerprint extracted by the improved SIFT has the characteristics of higher discrimination, stronger robustness and lower time complexity of video fingerprint extraction. 我们对SIFT方法进行改进提取视频指纹,改进后的SIFT视频指纹区分度更高、鲁棒性更强,并且视频指纹提取时间复杂度较低。
