FACE DETECTION USING TRANSFORM METHODS ,HELP WANTED - tniranjan9 - Feb 6 21:20:00 2002
|
HELLO FRIENDS, I want to detect an image from a set of images using matlab.I did using correlation.Is there any transform method i.e like fourier transform or any other way(pattern recognisation method) to detect a face of an image.If any one can tell where i can get material it would be great help to me. thanks in advance niranjan |

Hi Niranjan, If I understood correctly this is what you are looking for. You have a reference image and you want to find a best match from several images..right? This seems like you can do SAD (Sum of Abs difference) for each image and take the one which is giving minimum SAD that will give the image which will have high correlation. -biju --- tniranjan9 <> wrote: > HELLO FRIENDS, > I want to detect an image from a set of images using > matlab.I did > using correlation.Is there any transform method i.e > like fourier > transform or any other way(pattern recognisation > method) to detect a > face of an image.If any one can tell where i can get > material it > would be great help to me. > thanks in advance > niranjan > > ------------------------ Yahoo!

tniranjan, "Digital Imaging" by Gonzalez and Woods is a good book. Published 1992.
