hi i have a set of RGB images of diff faces (of people )as a 2 dim numpyarray ..something like threefaces=array([[xa1,xa2,xa3], [xb1,xb2,xb3], [xc1,xc2,xc3]]) where xa1,xa2,xa3 are tuples each representing rgb values of a pixel of first image ..
i need to create the average face image and display it.problem is i need to calculate (xa1+xb1+xc1)/3 etc to calculate avearge value of each pixel.how can i do this calculation.do i need to convert the r,g,b in to a single value for each pixel? the average value of a pixel will be a float isn't it? how can i create a PIL image from this? any help,directive greatly appreciated eric -- http://mail.python.org/mailman/listinfo/python-list
