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 is extracted and used to assist inverse halftoning, b) cross-scale 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… Expand

Inverse halftoning using wavelets
TLDR
This work introduces a new approach to inverse halftoning using nonorthogonal wavelets and shows that this simple wavelet-based approach outperforms the best results obtained from inverse Halftoning methods published in the literature, which are iterative in nature. Expand

TLDR
A novel wavelet-based approach to recover continuous-tone (contone) images from halftone images is presented that lends itself to practical applications since it is independent of parameter estimation and, hence, universal to all types of halftoned images, including those obtained by scanning printed halftones.
