PLOW Filter for Color Image Denoising
In this paper, a denoising approach, which exploits patchredundancy for removing Gaussian noise from RGB color images is described. Both geometrical and photometrical similarity of image patches have to be considered for learning the parameters of this Patch-based Locally Optimal Weiner(PLOW) filer. K-means clustering,with LARK(Locally Adaptive Regression Kernel) features, is used to identify t...

متن کاملColor Filter Array Image Analysis for Joint Denoising and Demosaicking
A single-chip image sensor used in almost all consumer and in some professional-grade digital cameras today is affixed with an alternating pattern of spectrally shifted (in the electromagnetic wavelength sense) color filters to each pixel location. The arrangement of color filters, which are typically the canonical color triples (i.e. red, green, blue), is called color filter array (or CFA) [1,...
متن کاملA Color Image Denoising By Hybrid Filter for Mixed Noise
Image denoising is the manipulation of the image data to produce a visually high quality image. At present there are a variety of methods to remove noise from digital images. There are different types of filters like mean filter, median filter, bilateral filter, wiener filter etc. to remove a single type of noise such as salt and pepper noise, speckle noise, Gaussian noise etc. But if the image...
متن کاملColor Image Denoising Using Decision Based Vector Median Filter
A new Decision based algorithm for impulse identification in color images is proposed. In vector median filter all the pixels are processed irrespective of whether it is corrupted or uncorrupted. The proposed algorithm overcomes this drawback where Vector Median is calculated only if the processing pixel is corrupted. This in turn reduces the computation time. The proposed algorithm gives bette...
