A Demosaicking Algorithm with Adaptive Inter-Channel Correlation
Most common cameras use a CCD sensor device measuring a single color per pixel. Demosaicking is the interpolation process by which one can infer a full color image from such a matrix of values, thus interpolating the two missing components per pixel. Most demosaicking methods take advantage of inter-channel correlation locally selecting the best interpolation direction. The obtained results loo...
متن کاملDemosaicking using inter-channel correlation in wavelet domain
In this paper, we propose a demosaicking method that uses a correlation between the wavelet subband coefficients in the high frequency region of color channels (R, G and B). In this paper, we introduce the pre-existing demosaicking methods, and show that our proposed method yields an outstanding performance through in imitation tests compared to pre-existing methods in terms of objective perfor...
متن کاملInter Channel Correlation based Demosaicking Algorithm for Enhanced Bayer Color Filter Array
Demosaicking is a process of obtaining a full color image by interpolating the missing colors of an image captured from a digital still and video cameras that use a single-sensor array. In this study a new Color Filter Array (CFA) is proposed. Which is based on the actual weight of the Human Visual System. It is developed based on the sensitivity level of the human eye to red as 29.9%, green as...
متن کاملDenoising Algorithm for CFA Image Sensors Considering Inter-Channel Correlation
In this paper, a spatio-spectral-temporal filter considering an inter-channel correlation is proposed for the denoising of a color filter array (CFA) sequence acquired by CCD/CMOS image sensors. Owing to the alternating under-sampled grid of the CFA pattern, the inter-channel correlation must be considered in the direct denoising process. The proposed filter is applied in the spatial, spectral,...
متن کاملAdaptive demosaicking
Digital still color cameras sample the visible spectrum using an array of color filters overlaid on a CCD, such that each pixel samples only one color band. The resulting mosaic of color samples is processed to produce a high-resolution color image, such that a value of a color band not sampled at a certain location is estimated from its neighbors. This is often referred to as ‘‘demosaicking.’’...
