An Effective Color-difference-based Demosaicking Method
This paper proposes an effective color-difference-based (ECDB) interpolation algorithm for color filter array (CFA) image demosaicking. A CFA image consists of a set of spectrally selective filters which are arranged in an interleaved pattern such that only one color component is sampled at each pixel location. To improve the quality of reconstructed fullcolor images from CFA images, the ECDB a...
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.’’...
متن کاملSelf-similarity Driven Demosaicking
Digital cameras record only one color component per pixel, red, green or blue. Demosaicking is the process by which one can infer a whole color matrix from such a matrix of values, thus interpolating the two missing color values per pixel. The selected color configuration of the sensor usually follows the Bayer color filter array, CFA. Out of a group of four pixels, two are green (in quincunx),...
متن کاملMathematics for demosaicking
Digital color cameras sample the continuous color spectrum using three or more filters; however, each pixel represents a sample of only one of the color bands. This arrangement is called a mosaic. To produce a full-resolution color image, the recorded image must be processed to estimate the values of the pixels for all the other color bands. This restoration process is often called demosaicking...
متن کاملCost-effective multiframe demosaicking based on bilateral filtering
A simple but effective multiframe demosaicking method is proposed. Its primary goal is to replace more expensive mechanical motion compensation systems. Therefore, it is designed to be easily implemented in hardware for consumer devices. The described multiframe demosaicking algorithm is suitable for mass production devices such as mobile phones or digital cameras. It is compared to a multifram...
