i have an image which created by camera. i almost correct this image color with the real image. for example; for a pixel's RGB values were changed [23 212 122] to [34 240 100]. but after this process (least square matrix method) my image has some noise around the edges of my image. how can i get rid of this noise?

You'd have to show the image, because I don't know why the noise only shows up around the edge of the image. Is that a darker or brighter color than you used in your training set?

this image is after some color correction processes. after i applied to it a couple filters median,... , the image was not seen well i mean it is not clear as before the filters. i am beginner about the image processing and can it be normal to get this result?

try doing the same process to a matrix of ones and using ./ to get rid of the vignetting effect. Probably, whatever you're doing forces matlab to fill in with zeros at the edges.
