How to find regions of any image using active contour

I = imread('toyobjects.png'); imshow(I) hold on title('Original Image'); mask = false(size(I)); mask(50:150,40:170) = true; contour(mask,'Color','b'); w = activecontour(I, mask, 200, 'edge'); contour(bw,'Color','r'); title('Initial contour (blue) and final contour (red)');

Hello Komal,

Please make your code readable. And you forgot to attach your image as well.

For detecting regions in an image, you can use this method as well:

 clc;
close all;
grayImage = imread('random.png'); 
[rows, columns, numberOfColorBands] = size(grayImage);
if numberOfColorBands > 1
  grayImage = grayImage(:, :, 2);
end
subplot(2, 1, 1);
imshow(grayImage, []);
title('Original Grayscale Image');
binaryImage = grayImage > 128;
binaryImage = imclearborder(binaryImage);
binaryImage = bwareaopen(binaryImage, 1000);
subplot(2, 1, 2);
imshow(binaryImage, []);
title('Binary Image');

It works pretty well and is able to detect all type of regions.

I have attached my image as well. Use that for proper understanding.
