Deep learning-based image signal processor (ISP) models for mobile cameras can generate high-quality images that rival those of professional DSLR cameras. However, their computational demands often make them unsuitable settings. Additionally, modern employ non-Bayer color filter arrays (CFA) such as Quad Bayer, Nona and QxQ Bayer to enhance quality, yet most existing deep ISP (or demosaicing) f...

Reductive leaching in the Bayer cycle using iron (2+) allows for Al extraction to be significantly increased through magnetization of Al-goethite and Al-hematite. However, use expensive salts or powder as a source leads significant increase production costs. In this work, feasibility new method, reductive bauxite an electrolysis process, was investigated. The reduction minerals boehmitic both s...

To synthesize a holographic color image, one can sequentially take three holograms at different wavelengths, e.g., at red (R), green (G) and blue (B) parts of the spectrum, and digitally merge them. To speed up the imaging process by a factor of three, a Bayer color sensor-chip can also be used to demultiplex three wavelengths that simultaneously illuminate the sample and digitally retrieve ind...

Fiber optics are widely used in flexible endoscopes which are indispensable for many applications in diagnosis and therapy. Computer-aided use of fiberscopes requires a digital sensor mounted at the proximal end. Most commercially available cameras for endoscopy provide the images by means of a regular grid of color filters what is known as the Bayer Pattern. Hence, the images suffer from false...

A modification to the standard Bayer CFA and photodiode structure for CMOS image sensors is proposed, which we call 2PFC, meaning “Two Pixel, Full Color”. The blue and red filters of the Bayer pattern are replaced by magenta filters. Under each magenta filter are two stacked, pinned photodiodes; the diode nearest the surface absorbs mostly blue light and the deeper diode absorbs mostly red ligh...

Although most digital cameras acquire images in a raw format, based on a Color Filter Array that arranges RGB color filters on a square grid of photosensors, most image compression techniques do not use the raw data; instead, they use the rgb result of an interpolation algorithm of the raw data. This approach is inefficient and by performing a lossless compression of the raw data, followed by p...
