Using wavelet networks in image compression

Abstract

At present, the combination of wavelet analysis and neural network is an active research area. This paper presents a method of image compression based on wavelet neural network. Wavelet network is the tight combination of wavelet decomposition and neural network, where wavelet basis function works as the activation function. Wavelet network is used to compress images in this paper, and the comparison between wavelet network and traditional neural network is presented here. The result shows that wavelet network method succeeded in improving performances and efficiency in image compression.
