Try psnr() and ssim(), both in the Image Processing Toolbox. See wikipedia for definitions.

thank you for your reply in my case, the two images are the results, so I don't have a reference image how I can say, with the fonctions that you have provided me, this image is more good than the other

What's your definition of good? Is a photo of a puppy "more good" than a photo of a kitten?

I'm talking about mosaic reconstruction the one that offers a better reconstruction: less distortion, interfacts ... visually we can see it. however, what I'm looking for is quantitative quality measurements Thanks for your help

I don't have the details. I don't already have the code just ready to hand over to you. Really, I don't. The details can be found in the link. Did you drill down into any of the links?
