Abstract: Anovelapproach for biomedical colour image enhancement method is proposed in this paper by using mathematical analysis of dual tree complex wavelet transform. The doctor requires the enhanced medical images to give better diagnosis. Thecontrast of biomedical colour images can be improved by data directionality of dual tree complex wavelet transform. The reduction in noise can be done by using wavelet coefficient shrinkage. In this paper we reduced noise present in both enhancedand non-enhanced medical colour images. We have taken the tumour image and computed the PSNR and SSIM of both enhanced image and proposed method by applying Gaussian noise, Poisson noise and speckle noise.
