We propose two new types of random patterns with R, G, B colors, which allow to design color filter arrays (CFAs) with good spectral properties. Indeed, the chrominance channels have blue noise characteristics, a property which maximizes the robustness of the acquisition system to aliasing. With these new CFAs, the demosaicking artifacts appear as incoherent noise, which is less visually distur...

The January 2009 Computer Journal special issue focuses on the super-resolution (SR) of images and video. The term SR is used to describe the process of obtaining a high-resolution (HR) image, or a sequence of HR images, from a set of low-resolution (LR) observations. This process has also been referred to in the literature as resolution enhancement (RE). SR has been applied primarily to spatia...

Video compression is an important procedure for digital applications. A commonly used format inputs to video coders YUV420, which a subsampled result from YUV444, that transformed and demosaicked color filter array (CFA) format. The process of chroma subsampling crucial step the reconstructed image quality. state-of-the-art method utilizes solution prior compute starting point, devises search i...

Image demosaicking and denoising are the two key fundamental steps in digital camera pipelines, aiming to reconstruct clean color images from noisy luminance readings. In this paper, we propose study Wild-JDD, a novel learning framework for joint wild. contrast previous works which generally assume ground truth of training data is perfect reflection reality, consider here more common imperfect ...
