Abstract:

||To address organizational and retrieval of news video of news video content-based segmentation of the issue,we proposed a new shot segmentation method using adjacent frame difference between the characteristic values to determine the initial shear lens position.The Eigenvalue poor adaptive threshold can be adjusted and the potential location for the camera flash can be detected. Test results show that the algorithm can quickly and accurately detect news video camera shear. Which recall rate and precision to achieve an average of 94% and 89%, higher than the original methods have improved.

Key words: news video, shot segmentation, mean histogram covariance
