WebAug 14, 2006 · In this paper, we present a method for removing noise from digital images corrupted with additive, multiplicative, and mixed noise. An image patch from an ideal image is modeled as a linear combination of image patches from the noisy image. We propose to fit this model to the real-world image data in the total least square (TLS) sense, because … http://personales.upv.es/asala/DocenciaOnline/Video/tls52EN.html
