Color Average and Variance adjustment

Hi! I am working on a project that requires the adjustment of color average and variance of an image based on another image. This is the sample image. I want to adjust the color average and variance of the umbra region based on the values of the sunshine region.
I got the average and variance of the images using:
mean_sunshine=mean2(nonzeros(sunshine{1}))
var_sunshine=var(nonzeros(double(sunshine{1})))
mean_umbra=mean2(nonzeros(umbra{1}))
var_umbra=var(nonzeros(double(umbra{1})))
How to I perform the adjustments after computation? Thanks :)

Just do something within the mask, for example
yourImage(mask) = slope * yourImage(mask) + offset;
