hi

i am working on an image analysis and control loop process for my electronics printer and i want to generate a code that would recognise the printed line width of the print from the image acquired after printing.

I'd do color segmentation first. Try the Color Thresholder on the Apps tab.

Then, once you have the segmented image, I'd assume the blob is a long curvy snake or rectangle and you can get the area and perimeter with regionprops() and then divide to get the length

props = regionprops(mask, 'Area', 'Perimeter');
% Area = length * width
allAreas = [props.Area];
allPerimeters = [props.Perimeter];
% Divide by half the perimeter, which is approximately the length.
allLengths = allAreas ./ (allPerimeters/2);

@shriramlkarni kulkarni did that work for you?

No @Image Analyst

I have attached Images for refrence and what I aim to find

Image 1 is Spiral RGB, 2 is Binary, 3 is the edge detection, 4 is what i intend to find i.e the average width of all the spiral print

But you don't want those images, right? Because if we get something for that, it may not work on the original images you posted because they're completely different.

OK, no answer so I guess you figured it out on your own.
