L0 sparse graphical modeling
Graphical models are well established in providing compact conditional probability descriptions of complex multivariable interactions. In the Gaussian case, graphical models are determined by zeros in the precision or concentration matrix, i.e. the inverse of the covariance matrix. Hence, there has been much recent interest in sparse precision matrices in areas such as statistics, machine learn...
متن کاملPATIL, RAJWADE: POISSON NOISE REMOVAL FOR IMAGE DEMOSAICING 1 Poisson Noise Removal for Image Demosaicing
With increasing resolution of the sensors in camera detector arrays, acquired images are ever more susceptible to perturbations that appear as grainy artifacts called ‘noise’. In real acquisitions, the dominant noise model has been shown to follow the Poisson distribution, which is signal dependent. Most color image cameras today acquire only one out of the R, G, B values per pixel by means of ...
متن کاملPoisson Noise Removal for Image Demosaicing
Most color image cameras today acquire only one out of the R, G, B values per pixel by means of a color filter array (CFA) in the hardware producing the so called ‘CFA image’. In-built software routines are required to undertake the task of obtaining the rest of the color information at each pixel through a process termed demosaicing. The most common CFA pattern is the well-known Bayer pattern ...
متن کاملEnhanced Cellular Automata for Image Noise Removal
Cellular Automata (CA) are a type of complex systems based on simple and uniformly interconnected cells. They provide an excellent method to perform complex computations in a simple way. CA can be used in image processing, because of the simplicity of mapping a digital image to a cellular automata and the ability of applying different image processing operations in real time. Noise removal is c...
