MATLAB: Thermal image, find fault

Question

Hi all,

I have a thermal image like below. I pasted link there.

I want to find a fault position over there, but image have simultaneous places like lines. Can we bypass this, because when we convert it gray scale and threshold after that the fault place and normal place is being together.

Can we remove this lines from image, and image can be improved?

thanks all.

This is the pseudocolored rgb image:

this is binary and image processed.

Answer 1

Without the colormap, this image is almost worthless - it's impossible to get back the original thermal image. Why don't you have the original image? It starts out as a monochrome image and then you apply a colormap and save it. Why can't you just not apply the colormap? You have the image, just save it without any colormap. Analysis will be a lot easier after that.
