AUTOMATIC ASSINCHRONOUS VIDEO DEMULTIPLEXING


The work on real forensics videos involving banking images lead to the method presented here: a software approach to the problem of demultiplexing time multiplexed security videos. This approach is of particular interest in cases in which, for some reason, the regular demultiplexing hardware/software is not available. Based on comparisons of the mean frame luminance and having low frequency characteristics of the scenes as references, this approach is being used with good results by video experts in Brazil to help locating sequences of particular interest in surveillance time multiplexed videos recorded in magnetic video cassettes.
