Title: Image Enhancement System Using Wavelet Transform and a Non-Linear Piecewise Filter
Authors: P.Thangavel and S.Gopinathan
Abstract: We propose an image enhancement scheme by using wavelet transform and a smooth approximation of a piecewise non linear filter. The wavelet transform is used to detect image edges. Noise smoothening and sharpening is achieved by using the smooth approximation of the piecewise linear filter. Key feature of the proposed technique is its better performance than the other methods in the enhancement of images corrupted by Gaussian noise. Experimental results show that such a filtering scheme can achieve a considerable improvement in noise smoothing, details-preserving and the visual quality.
Keywords: Wavelet, Non linear filter, Image enhancement.
