K. S. Tamilselvan, G. Murugesan, M. Vinothsaravanan . A Histogram based Hybrid Approach for Medical Image Denoising using Wavelet and Curvelet Transforms. International Journal of Computer Applications. 74, 21 ( July 2013), 6-11. DOI=10.5120/13040-0053
Medical images are analyzed for the diagnosis of various diseases like cancer, tumor and fracture etc. . . But, they are susceptible to different types of noises called as Gaussian noise, Speckle noise, Uniform noise, Impulse noise, etc. . . Therefore it is an important task to remove the noise from medical images especially in MRI,CT, PET,SPECT, Digital Mammogram and Ultrasound images. Selection of appropriate filter is a tough task. In this paper, we propose a technique that uses Wavelet Transform and Curvelet Transform for denoising the medical images based on the Histogram equalization.
