Image error calculation [message #70287]

Hi I basically have a 400x400 jpg image that I have obtained by
combining 22 similar images. I am currently trying to determine if the
new image produced is better in quality than the original image that I
used as a base.

(With my extremely limited knowledge of images) I have tried to do
this by using the statistic command and looking at the standard
deviation (hence error of image). However I do have an alarming sense
that I am running into a mistake.

Would it be possible if anyone could tell me what IDL procedures or
methods you use to determine 'image quality' quantitatively?

Thanks for your help in advance
