how use immse between two color images

how can i compute the differncebetween two RGB images, mean sqaue error and peak signal noise ratio PSNR

[Yusuf lamah]

thank you very much Majid means dont need to convert matrix to array or separate the components of RGB R alone and G then B

U're welcome. No, That's enough.

Hi Yusuf,

You can calculate MSE and PSNR between 2 rgb images A and B like this:

MeanSquareError=immse(A,B)
PeakSignaltoNoiseRatio = psnr(A,B)

You don't need anything else!
