[QUOTE="ziphnor, post: 70389, member: 14215"] Doesnt scanning diagonally put you in danger of 'discovering' logos?(many channels have logos in the top left corner). I think its best to scan down the middle since thats where the 'action' is. I would prefer to decrease pixel checks by means of binary search. Ie, start by checking the middle of the screen, if it has image content, try 1/4 up/down(depending on scan direction) etc. To further decrease time complexity i am considering the histogram technique suggested, but with one histogram per color component(ie YUV or RGB). The max number of different values over all components seen would then decide if it was image content or not, with an added check for occurrence of high brightness. [/QUOTE]
