Shot Boundary Coefficient Model and Its Application Based on Windowed Frame Differences
Ran Xin · Dianzi xuebao · 2006
To aim at video structure analysis,a new shot boundary coefficient model is proposed.Firstly,windowed frame differences are calculated using the special approaches,which have different characteristics for intra-shot frames and shot transition frames respectively.Secondly,shot boundary detection operators are used to calculate shot boundary similarity coefficients.If shot boundary similarity coefficients are bigger,corresponding frames are more probably shot boundaries.Thirdly,to improve shot boundary similarity coefficients,shot boundary coefficients are defined based on shot boundary similarity coefficients.Shot boundary coefficients have many good characteristics,and are used to not only detect shot boundaries independently,but also combine traditional shot boundary detection methods for shot boundary detection.Therefore,a robust shot boundary detection framework is provided.Experimental results show that shot boundary detection methods,based on the shot boundary coefficient model,can improve the performance of shot boundary detection.
