@amits180891 you can find all shaders in "GPUImage2/framework/Source/Operations/Shaders/"

HarrisCornerDetector_GL.fsh (or GLES) NobleCornerDetector_GL.fsh (or GLES) ShiTomasiFeatureDetector_GL.fsh (or GLES)

All mentioned filters work is done by this shaders, respectively.

This is an iOS / Mac / Linux project. If and when Swift becomes a viable language on Android, I may port this over. Until then, you can look at the shaders themselves and roll your own version of this natively.
