The spider genus Fecenia was erected by Simon (1887). Together with the genus Psechrus Thorell, 1878, Fecenia Simon, 1887 belongs to the family Psechridae Simon, 1890 (Platnick 2013), a group of araneomorph, entelegyne and cribellate spiders (Bayer and Jäger 2010). The presence of this spider genus in India, which belongs to the Lycosoidea within the retrolateral tibial apophysis (RTA)-clade (G...

Bayer Pattern Color Filter Arrays (CFAs) are widely used in digital photo and video cameras. Generally these images are corrupted by a signal and exposure dependent quantum noise. An automatic image processing carrying out within camera usually implies a gamma and color corrections and an interpolation. And at the same time the noise in the image becomes non-quantum and spatially correlated. Th...

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...

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...
