Description. similarity = dice (BW1,BW2) computes the Sørensen-Dice similarity coefficient between binary images BW1 and BW2. similarity = dice (L1,L2) computes the Dice index for each label in label images L1 and L2. similarity = dice (C1,C2) computes the Dice index for each category in categorical images C1 and C2.

How to calculate Dice coefficient for measuring accuracy? Thank You! Edits: I used the following code for measuring the dice similarity for my original and the segmented image but it seems to take hours to calculate: for i in xrange (0,7672320): for j in xrange (0,3): dice = np.sum ( [seg==gt])*2.0/ (np.sum (seg)+np.sum (gt)) #seg is the segmented image and gt is the original …

02.11.2021 · There might be two ways: We calculate the Dice coefficient for each image, and then take the average for all images. We flatten all of them into an array of size N × H × W, then calculate the Dice coefficient for this array. I do not know which way is usually used in medical image segmentation. I have tried to search for some papers, but they ...
