Event camera. An event camera, also known as a neuromorphic camera, [1] silicon retina [2] or dynamic vision sensor, [3] is an imaging sensor that responds to local changes in brightness. Event cameras do not capture images using a shutter as conventional (frame) cameras do. Instead, each pixel inside an event camera operates independently and ...
Image noise. Image noise is random variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the image sensor and circuitry of a scanner or digital camera. Image noise can also originate in film grain and in the unavoidable shot noise of an ideal photon detector.
Twisted Pixel Games, LLC. Twisted Pixel Games, LLC is an American video game developer based in Austin, Texas. Originally a contractor, Twisted Pixel releases games based on its own intellectual properties such as The Maw and 'Splosion Man. The company uses its own proprietary engine, known as Beard, to power its games.
Pixelfed. Pixelfed is a free and open-source image sharing social network service. [3] [4] The platform distinguishes itself from other image sharing services through its decentralized architecture, meaning user data is not stored on a central server. [5] [6] It uses the ActivityPub protocol, allowing users to interact with other social ...
t. e. The scale-invariant feature transform ( SIFT) is a computer vision algorithm to detect, describe, and match local features in images, invented by David Lowe in 1999. [1] Applications include object recognition, robotic mapping and navigation, image stitching, 3D modeling, gesture recognition, video tracking, individual identification of ...
Pixel shifting by movement of one or more sensors is a technique to increase resolution [3] and/or colour rendering [4] of image capturing devices. The image at right displays the visible gain both in detail and in colour resolution produced by the Sony α7R IV 16-shot pixel shift mode, which results in a 240 Mpixel image, as compared to a ...
Fixed-pattern noise. Fixed-pattern noise (FPN) is the term given to a particular noise pattern on digital imaging sensors often noticeable during longer exposure shots where particular pixels are susceptible to giving brighter intensities above the average intensity.
