1) Determine the centroid of the image - This step is easy enough using regionprops. 2) Start tracing the boundary (clockwise or counterclockwise, doesn't matter), from the point where a line drawn parallel to the y-axis, and through the centroid, first crosses the boundary of the particle.

Convert the image to a binary image. bwtraceboundary and bwboundaries only work with binary images. BW = im2bw (I); imshow (BW) 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

Trace Boundary and Visualize Contours Try This Example Copy Command Read an image and display it. BW = imread ( 'blobs.png' ); imshow (BW) Pick an object in the image and trace the boundary. To select an object, specify a pixel on its boundary.
Boundary tracing - Wikipedia
https://en.wikipedia.org/wiki/Boundary_Tracing
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.

I am trying to compute contour of a binary image. Currently i identify the first non zero and the last non zero pixel in the image through looping. Is there a better way? i have encountered few functions: imcontour (I) bwtraceboundary (bw,P,fstep,conn,n,dir) But the first doesn't return the x and y coordinates of the contour.

I have a binary image and I want to extract the co-ordinates of the contour of the binary image.The built in contour() functions resulted in double values, but instead I want the array i.e. series ...
