Distance transform of binary image - MATLAB bwdist - MathWorks

WebDescription. D = bwdist (BW) computes the Euclidean distance transform of the binary image BW . For each pixel in BW, the distance transform assigns a number that is the distance between that pixel and the nearest nonzero pixel of BW. [D,idx] = bwdist (BW) also computes the closest-pixel map in the form of an index array, idx. smallest cell in the body
