Gradual transition detection in shot boundary using gradual curve point

Video shot boundary detection (SBD) is a fundamental step in automatic video content analysis. Gradual transition is based on the gradual curves characterised by distribution of average edge information in the sequence of frames. An average edge frame is obtained from optimal edge detector. Features are extracted based on the minimum difference between the sequences of frames. The minimum variance in the local frame sequence is chosen as a gradual curve point. Finally, the performance is computed based on the precision (quality) and recall (quantity) value.
