How to analyze a Matlab Figure (.fig) file of feature extraction using web-based application

My project intends to evaluate feature extraction techniques by measuring the quality of extracted image through web-based application. Can anyone tell me is there any web-based software or application to analyze a Matlab Figure (.fig) file of image feature extraction? Below are the samples of my extracted images (uploaded in JPEG form).

Well I have no idea if those images you produced are any good or not, especially since you didn't even upload the original image or tell us what feature you were trying to measure. Maybe you could get an expert in the field to hand extract some feature, like outline it or something, or else give you a 1-10 grade on how well those images portray the information that you hoped it would.

No, those are what you called above "samples of my extracted images", in other words, output images, NOT your original input image.

MATLAB .fig files are really just .mat files, and can contain a variety of structured data including information about graphic structures, callback functions, and so on. Within the .fig file there might be an image() object whose CData property is the color data. Something that analyzed .fig files would be mostly a matter of digging through the .fig file to find the image() object, extracting the data array from the CData property, maybe converting it TrueColor (see the File Exchange contribution freezeColor() for that task), and then sending it to the analysis routine. The hard work would be in the analysis routine; the rest is mostly cosmetics.
