Take a look at these lectures: https://www.youtube.com/watch?v=h_fYIs0hdL0&index=65&list=PLZ9qNFMHZ-A79y1StvUUqgyL-O0fZh2rs

I am currently trying to implement a sparse dictionary based on RGB images. Still in development though

D. Regan

Thank U Kim. I came across many IEEE papers worked on Sparse representation on image denoising. If U have any more kindly share.

My suggestion would be , find this book : Advanced Engineering Math by E. Kreyszig - Numeric ODEs and PDEs has lattice points analysis for 2D grids. That would give you information of how to construct a spare matrix or identify one.
