@Image Analyst the white i meant is something like this in the attached image , so using my above code i need to find the histogram of x axis
LM axis = MyImldrgyvCol(2,:)
LMhist = imhist(LM axis);
median = median(LMhist) (% so by median here i mean the white point here to be set as median) -- is this possible?

This was created by my team 4 yrs ago, now I am doing the same thing in color so I need this median grey in that particular axis to know how i can rectify from the particular value .
