Effect of adaptive thresholding on shot boundary detection performance

摘要

Effect of adaptive threshold on shot boundary detection performance is analyzed in this paper, where the threshold is used to determine whether a target frame is a shot boundary or not in a broadcasting video content. Adaptive threshold is calculated using input threshold and visual similarities of adjacent frames of a target frame. The experimental results show that application of adaptive threshold improves shot boundary detection performance in terms of precision-recall values and the variance of the values considerably decrease.
