I have applied chain code on images for predicting the object as normal and worn. Now I have to apply confusion matrix on those images so that precision can be calculated. But the problem is chain code for both the images i.e. chain code for normal object and worn object are different. Matrix dimensions are different for both and hence I am unable to get desired results. How I can get the desired values for true positive,false positive,false negative,true negative ? Are there any other parameters which can be used in this case?
