Calculate the conrast by the difference between the highest and lowest intensity value

I would like to calculate the image Contrast which I defined as the difference between the highest and lowest intensity value of the image. However I want to ignore a certain percentage of pixels to account for outliers (otherwise a single white and black pixel would lead to "full contrast")
How can I ignore any values outside mean+-std andt hen I will calculate the max(img)-min(img) ?
Thank you so much

You could use medfilt2 or medfilt3 to get rid of the outliers. You could then use discretize to bin the data into bins of width 2*std for the purposes of computing contrast.
