SingleChannel Sparse NonNegative Blind Source Separation

Abstract In this paper, we propose a novel method for single-channel blind separation of nonoverlapped sources and, to the best of our knowledge, apply it for the first time to automatic segmentation of lung tumors in positron emission tomography PET images. Our approach first converts a 3-D PET image into a pseudo-multichannel image. Afterward, regularization free sparseness

CiteSeerX Ensemble Learning for Blind Image Separation

When applying these ideas to the problem of deconvolving images two problems become apparent. Firstly in many real data sets for instance the images generated by telescopes observing the sky or the power spectrum from a Nuclear Magnetic Resonance NMR spectrometer the pixel values correspond to intensities. So the pixel values must be positive.

210206802 Blind stain separation using modelaware

Feb 12, 2021 Multiple stains are usually used to highlight biological substances in biomedical image analysis. To decompose multiple stains for co-localization quantification, blind source separation is usually performed. Prior model-based stain separation methods usually rely on stains spatial distributions over an image and may fail to solve the co-localization problem. With the advantage of
