Boundary tracing, also known as contour tracing, of a binary digital region can be thought of as a segmentation technique that identifies the boundary pixels of the digital region. Boundary tracing is an important first step in the analysis of that region. Boundary is a topological notion. However, a digital image is no topological space.

The conventional tracing of the boundary (implemented in MATLAB) along the centers of the pixels at the edge of a foreground object. C. Our algorithm traces the boundary directly along the lines separating the foreground and background pixels.

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.

The boundary includes left boundary, leaves, and right boundary in order without duplicate nodes. (The values of the nodes may still be duplicates.) The left boundary is defined as the path from the root to the left-most node. The right boundary is defined as the path from the root to the right-most node. If the root doesn’t have left subtree or right subtree, then the root …

Set the current pixel as p ; Add this non zero pixel into a boundary pixel list. Set the previous pixel from where p is entered as b (Backtracked pixel ) Take a 3 * 3 neighborhood of p and search for the next clockwise nonzero pixel from b in clockwise direction. Repeat the steps 3 to 5 until p is same as S. C++.

The code is: I = imread ('C:\...\images3.jpg'); imshow (I) BW = im2bw (I); imshow (BW) dim = size (BW) col = round (dim (2))-90; row = min (find (BW (:,col))) boundary = bwtraceboundary (BW, [row, col],'N'); imshow (I) hold off; plot (boundary (:,2),boundary (:,1),'b','LineWidth',1);
Source code for tracing boundaries and image reconstruction

The tracing is performed in combinatorial coordinates. The program goes from one boundary point to the next one along the boundary cracks. To recognize the next boundary crack the program tests two pixels "Pos" and "Neg" lying ahead of the actual crack. The program calculates the coordinates of these pixels by adding the 2D vectors "Positive [direction]" and …

Pad the image with a white 1 pixel wide border. Start scanning from the top-left position and scan each pixel from left to right downwards. When a black pixel is found, trace around the contour in a clockwise direction. Tracing the contour is done by checking the 8 neighbors and see if they are black.
