AUTOMATIC ASSINCHRONOUS VIDEO DEMULTIPLEXING
demultiplexingvideoforensics
Resumo
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.
