Determine the row and column coordinates of a pixel on the border of the object you want to trace. bwboundary uses this point as the starting location for the boundary tracing. dim = size (BW) dim = 1×2 246 300 col = round (dim (2)/2)-90; row = min (find (BW (:,col))) row = 27 Call bwtraceboundary to trace the boundary from the specified point.

6. Border Tracing Algorithm
http://users.utcluj.ro/~rdanescu/PI-L6e.pdf
The border tracing algorithm is used to extract the contours of the objects (regions) from an image. When applying this algorithm it is assumed that the image with regions is either binary or those regions have been previously labeled. Algorithm’s steps: 1. Search the image from top left until a pixel of a new region is found; this pixel P 0

a) the algorithm "backtracks" when it goes backwards to visit an already visited pixel before tracing the whole boundary, and b) for every boundary edge there are 2 ways to "go through" it, namely "in" or "out" (where "in" means towards the inside of the corresponding polygon and "out" means towards the outside of the polygon).
Suzuki’s Contour tracing algorithm OpenCV-Python

Step-1 If it’s an outer border (i.e. f ij = 1 and f i,j-1 = 0) then increment the NBD and set (i2, j2) as (i, j-1). Else if it is a hole border, increment NBD. Set (i2, j2) as (i, j+1) and LNBD = f ij in case f ij > 1. Otherwise, go to step 3. Step-2 Now, from this starting point, we will trace the border. This can be done as

Contour Tracing Algorithms What follows are four of the most common contour tracing algorithms. The first two, namely: the Square Tracing algorithm and Moore-Neighbor Tracing are easy to implement and are therefore used frequently to trace the contour of a given pattern.
