*ImageJ can make use of specific plugins to deal with these features.
^&SFMetrics can be run from the scripts in any operating system with MATLAB installed.
^#Although ‘edge detection’ is a common feature in many software packages it is usually not adjustable or cannot be used as a binary mask to extract features from the original image.
