"This work addresses the separation of real-life nonlinear\nmixtures of images, which occur when a paper document is\nscanned and the image from the back page shows through.\nA physical model of the mixing process, based on the consideration of the halftoning process used to print grayscale images, is presented. The corresponding inverse model is then used to perform image separation. The parameters of the inverse model are optimized through the MISEP technique of nonlinear ICA, which uses an independence criterion based on minimal mutual information.\nThe quality of the separated images is competitive with\nthe one achieved by other techniques, namely by MISEP\nwith a generic MLP-based separation network and by Denoising\nSource Separation. The separation results show that\nMISEP is an appropriate technique for training the parameters and that the model fits the mixing process well, although not perfectly. Prospects for improvement of the model are presented."^^ . "2006" . . . . . . . . . . "Luís B."^^ . "Almeida"^^ . "Luís B. Almeida"^^ . . "Mariana S. C."^^ . "Almeida"^^ . "Mariana S. C.
