Abstract:

This paper introduces a new approach to inverse halftoning using nonorthogonal wavelets. The distinct features of this wavelet-based approach are: a) edge information in the highpass wavelet images of a halftone image is extracted and used to assist inverse halftoning, b) crossscale correlations in the multiscale wavelet decomposition are used for removing background halftoning noise while preserving important edges in the wavelet lowpass image, c) experiments show that our simple wavelet-based approach outperforms the best results obtained from inverse halftoning methods published in the literature, which are iterative in nature [1, 2].

Inverse halftoning has applications to image scaling, enhancement, facsimile image processing, and image compressi...
