This paper proposes a novel scene analysis algorithm based on three-dimensional discrete wavelet transform (3D DWT). Based on the correlation among the adjacent frames, video frames can be considered as four categories: abrupt scene transition, motion scene, gradual scene transition and static scene, which are ranked from low to high according to the strength of the correlation. Through the investigation...
SBD (Shot Boundary Detection) have great impact on effective browsing and retrieving of the video. It serves as the preliminary step to construct the content of videos. The Spatio-temoral local principle is used to detect shot boundary of videos. Based on careful analysis about the feature of videos, variable thresholds are used in different videos. A cooperative SBD model is proposed in the text...
