For the detection of shot boundary in a video sequence,the selection of a proper threshold for computing discontinuity values is an important and difficult problem.A formula for calculating discontinuity values is defined,then a new Gaussian model based technique is proposed,which needs not setting low boundary threshold. It is a kind of improvement of twin-comparison method. Primary experimental results demonstrate that the proposed method enables to locate boundaries of gradual transitions and cuts exactly and quickly.
