I have already used gabor filter (gaborfilterbank & gaborfeature which i downloaded from fileExchange) but when i input this image it gives me feature but mostly focused on edge rather than sclera part. How do i solve this problem? I am attaching those images
This is the magnetize gabor filter
This is the real gabor filter
Please help.

Why are you using Gabor filter? What do you want to measure, and how do you think Gabor will do that?

Gabor filter returns 1D matrix. Is it possible i can threshold this matrix because in matrix there are 0 or more than 0? If possible how can i apply adaptive thresholding or other? @ImageAnalyst

I don't really know. I don't use Gabor things. Sure, you can threshold globally or adaptively/locally - whatever makes sense to you.
