A Case Study on Contourlet and Ridgelet in Denoising Medical Images

Trương Hoàng Vinh
A special member of the transforming of multiscale in the frequency domain has been proposed and developed in the last few years ago. We mention here some transformations after X-let generation such as: Ridgelet, Contourlet, Bandelet [1,2,3,4]. Denoising image has been an important field in image processing, especially on medical image [7,8,9]. In order to diagnosing more and more exactly, the noise must have been removed completely after acquiring from the machine. This paper introduces the
more » ... parison of two model transform for denoising medical image. The results show that the Contourlet transform has more efficiency than the Ridgelet transform.
