Basic scene change detection
If i consider a stream of frames,
what i need to do in order to perform a simple scenechange detection, shall i work in luminance using the frame by frame difference? or shall i use an other algo? (The goal is to locate scenechange in a clip, for cleaning manually the crap that may be at the scenechange...) esby |

Afaik the VCR mod of Virtualdub (iirc www.virtualdub.net) has scene change detection, perhaps you can salvage the code. VirtualDub itself has some (for the buttons), but I think that in the mod was improved.

Virtualdub definitely has builtin scene change detection for the buttons, maybe take a look again at the buttons... Nandub simply uses that algo, with some custom additions, by the now defunct release group called 'ViRA'.
