A new approach based on Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) for medical image contrast enhancement is presented. The contrast of the input image is enhanced by proposed fusion technique between wavelet based masking using Cuckoo Search Algorithm (CSA) and mask based singular value decomposition. Resolution is enhanced by combining interpolated high frequency sub band and maximum value fused low frequency sub band using mask technique. Experimental results are
