Take measurement of a concrete crack from picture?

Hi there,

I have microscopic concrete crack footages of samples. And I need to measure how much that cracks' width/height/depth is.

Is there any way to do this in MATLAB?

Hey,

Following major steps will be required to detect the width and height of the concrete crack:

• Segmentation
• Finding connected components
• Getting image region properties

Segmentation can be done based on color threshold and median filter as illustrated in the following link:

For finding connected components and region property make use of bwconncomp and regionprops as illustrated in the following link:

Hope it helps!!

Sir please provide me complete code for finding crack length and width. It's useful to my final year project.
