How to Enhance Image edges after segment on Binary Image

Answers (1)

The simplest answer is to try using the edge function in the Image Processing Toolbox. Here is the doc. I tried it on your image to get an ok result. You might have to play with the algorithm/parameters to get a thicker/more defined edge:
img = imread('binary_image.png');
I = rgb2gray(img);
BW1 = edge(I,'sobel');
BW2 = edge(I,'canny');
figure;
imshowpair(BW1,BW2,'montage')
title('Sobel Filter Canny Filter');
(right click open image in a new tab/window for better resolution)
