MATLAB: How to count the number of pipes in an image

countImage Processing Toolboximage segmentationpipe

Hi! I need to inventory the number of pipes in a storage. I'm new using Matlab and I need to know if it's possible to count them using an image. Here's an example of the image.

Can someone help me with the code?

Thank you in advance

Try imfindcircles(). Here's a demo: http://www.mathworks.com/matlabcentral/fileexchange/34365-findcirclesgui

MATLAB: How to count number of white cirlces in a bw image

Use bwlabel():

[labeledImage, numRegions] = bwlabel(binaryImage);

MATLAB: Number of Object in binary image

Try this:

bw = imread('bw.png');
if ndims(bw) > 1
	bw = bw(:,:,1);
end
% Threshold
bw = bw > 128;
subplot(1, 2, 1);
imshow(bw, []);
% Fill holes
bw = imfill(bw, 'holes');
% Get areas
props = regionprops(bw, 'Area');
sortedAreas = sort([props.Area], 'descend')
% Looks like we need to throw away any blobs less than 1000 pixels or so
bw = bwareaopen(bw, 1000);
subplot(1, 2, 2);
imshow(bw);
% Count the blobs
[labeledImage, numBlobs] = bwlabel(bw);
fprintf('Found %d shapes.\n', numBlobs);
