I have created a back end code which is comparing two images using LABVIEW.i have used a comparator and put a tolerance factor which will help me filter out almost same images.the problem i am facing is that on subtraction of the given two images i am getting a completely random output with noise surrounding the parts of the image which are being compared.Also the tolerance percentage i have given has not been working very effectively.Kindly let me know if there is an easier solution to my task or what needs to be done
Thank you
