The pictures may be at different orientations to those given as training data. <br /> Does anyone any ideas on what network would be best (I was thinking back propogation) and algorithms to preprocess the image to orientate it.<br /> <br /> I inted to scale the pricture so that the actual face is always the same percentage of the whole image before feeding the pixel values into the net. <br /> <br /> The only way I can think of to find the orientation is to rotate the input points one unit at a time, monitoring the output to find the most likely image. This would seem to have a very large processing overhead though. Any thoughts?<br /> <br /> Cheers guys<br /> <br /> Tom<br /> http://www.programmersheaven.com/mb/Algorithms/170730/170730/neural-net-object-orientation/ Thu, 13 Feb 2003 07:49:37 -0700 Algorithms
