In commercial_skip.cpp, look at the following values:
CommDetect::CommDetect()
logoGoodEdgeThreshold
logoBadEdgeThreshold - these are the range for determining if the
number of edges detected in a logo area indicate
a logo is probably ther.
CommDetect::SearchForLogo()
edgeDiffs[] - this is the difference in pixel values that deteremines
if an edge exists. The logo detection code first tries
with the first value in the array and then
tries each of
the others until a logo is detected.
look for "(pixelsInMask > 50))" and bump that down if you want, that
determines the number of edge
