In the code we have (472*475*20) 3D array and if I view only one channel then the image is not correct. The image in hyperspectral viewer and the result is attached in the screenshot below

I can't run an image. I can only run code if it's in text form.
It looks like you have a lot of salt and pepper noise. You can remove it with a modified median filter like I've attached. Once removed, imagesc should scale it better. Alternatively you can use imadjust or imadjustn.
If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:
