@Navya Singam I used you the link above, it helped to show the label images but how to use it to find jaccrad index , the labeled image already black and gives low jaccard index as shown in attached images and following code:
A = logical(imread('7001-236.png'));
BW_groundTruth =logical(imread('Label_1.png'));
similarity = jaccard(A(:,:,1), BW_groundTruth)
similarity =
0.0925
