In the application of computer vision research, wavelets have enjoyed widespread popularity. In recent perspective some new age transforms like the corex transform, steerable Pyramid, ridgelets, contourlets and curvelets are theoretically appearing to the better image description for pattern recognition. These new transforms have been applications in the area of compression, denoising, watermarking and digital signature systems. In this paper, the authors will compare the performance of wavelets and contourlets for the purpose of pattern recognition cryptography.
