Trace object in binary image - MATLAB bwtraceboundary
https://www.mathworks.com/help/images/ref/bwtraceboundary.html
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. This example uses the coordinates of a pixel on the boundary of …

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.
Boundary tracing in matlab - Stack Overflow
https://stackoverflow.com/questions/5435201/boundary-tracing-in-matlab
I have already seen complex codes for boundary tracing in this site. I'm a 1st time Matlab user, with a small code with bwtraceboundary. This code once traced outline of a leaf image( though without tracing the leaf stalk, which was a lighter shade)... before I changed the image size. then all I get out of this, for any image, is a blank.

-use the first loop pair for height and one for width and trace any change i.e if a pixel is black and the next pixel is white draw that point onto a new mat. (i.e mark that point as 255 or of any colour you desire) -Do the same for width and height and store it into another mat. -Then add both the mats and average out the result.
Trace object in binary image - MATLAB bwtraceboundary

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. This example uses the coordinates of a pixel on the boundary of the thick white circle, obtained through visual inspection using impixelinfo.
