Ridgelet transform based directional features preservation in image denoising

An effective method for image denoising method for Straight Edge recovery is carried out by featuring one of the multi resolutions transforms the Ridgelet transform. The proposed work presents a novel approach of denoising by Ridgelet transform using different Wavelets, which is well suited for Straight Edge images consist of more details in the edges. Moreover, the high directional sensitivity of the Ridgelet transform makes the new method a very good choice for Straight Edge recovery. To preserve more edges with reduced number of computations, Radon transform is used instead of one dimensional wavelets in Ridgelet transform. Whereas the Ridgelet transform has good orientation character. The presence of noise not only produces undesirable visual quality but also lowers the visibility of low contrast objects. Noise removal is essential in imaging applications in order to enhance and recover fine details that may be hidden Edges and Curves. The empirical results indicate that these Multi resolution transforms have a wide- ranging future for eliminating the noise in the Straight Edge Images. The numerical results indicate that Ridgelet transform has a wide-ranging future for Directional feature realization.
