Hello everyone,
I captured some images from camera. My final aim to identify the material composition from the images. However before that i need to perform some image calibration, noise removal, feature extraction , dimensionality reduction. can you please suggest some code or routine to the do these task?
Also after this task, i wanted to apply classification algorithm so it can detect the material from it
Can you guys tell me a way to do in the Matlab. Thanks a ton.

You have to create a canvass large enough to contain them all, like say twice as tall and as many times wide as needed. Then figure out what line of the image contains the first brown line. Then paste that onto the same line in the canvass for all images. See my copy and paste example and adapt as needed.

Yes, it's probably better to just spend time to code up the algorithm I laid out.
