def rgbTopixelvalue((r,g,b)):
alpha=255
return unpack(l, pack(, b, g, r, alpha))[0]
That's much worse than averaging the R,G,B components.
oops!
the intention was to pack r,g,b components into a single value sothat
calculations like finding covariant matrix of a set of images

a) Work with the 3 components in parallel (that is, use 3 separate
matrices, one for each component, and regenerate the image at the
end).
that wd be ok for image generation ..but to calculate covariance
matrix from the set of images i don't know if it wd work

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

That says to get all elements from row 1 to the bottom that are in

err..
