Boundary Tracing in Binary Images Using Cell Complexes
https://link.springer.com/chapter/10.1007/978-981-16-5772-6_3
Now we describe two simplest algorithms “SearchBin” and “TraceBin” for tracing boundaries in a binary image containing no black pixels at the borders of the image. We shall consider the more general version without this limitation later. The tracing must retain black pixels at its right-hand side.

Call bwtraceboundary to trace the boundary from the specified point. As required arguments, you must specify a binary image, the row and column coordinates of the starting point, and the direction of the first step. The example specifies north …

Tracing boundary contours in a binary image
https://www.sciencedirect.com/science/article/pii/S0262885601000919
This paper presents a new contour tracing algorithm for tracing boundary contours in a 2D binary image, which plays a very important role in digital image processing, pattern recognition and machine vision system. The new algorithm has three main advantages compared to existing algorithms.

The first step is to find boundary points in the binary image by tracing technology [14], which is a proven technology and therefore not given here. Next, corner points are extracted from these ...

I want to trace the boundary of an object manually using python in binary images without using OpenCV. I am done with one object but I want to trace multiple objects in an image without using OpenCV findContours. original image : output image : I tried using the Moore neighborhood algorithm on binary images.
Tracing boundary contours in a binary image
https://www.sciencedirect.com/science/article/abs/pii/S0262885601000919
Abstract. This paper presents a new contour tracing algorithm for tracing boundary contours in a 2D binary image, which plays a very important role in digital image processing, pattern recognition and machine vision system. The new algorithm has three main advantages compared to existing algorithms. First, it never loses inner boundaries of arbitrary complicated regions.
Trace object in binary image - MATLAB bwtraceboundary
https://la.mathworks.com/help/images/ref/bwtraceboundary.html
B = bwtraceboundary (BW,P,fstep) traces the outline of an object in binary image BW. Nonzero pixels belong to an object and zero-valued pixels constitute the background. P specifies the row and column coordinates of the point on the object boundary where you want the tracing to begin. fstep specifies the initial search direction for the next object pixel connected to P. B holds the …

To trace the boundaries of all the coins in the image, use the bwboundaries function. By default, bwboundaries finds the boundaries of all objects in an image, including objects inside other objects. In the binary image used in this example, some of the coins contain black areas that bwboundaries interprets as separate objects. To ensure that bwboundaries only traces the …
