1. Pixel

   In digital imaging, a pixel, or pel, is a physical point in a raster image, or the smallest addressable element in a display device; so it is the smallest controllable element of a picture represented on the screen. The address of a pixel corresponds to its physical coordinates. LCD pixels are manufactured in a two-dimensional grid, and are often represented using dots or squares, but CRT pixels correspond to their timing mechanisms and sweep rates. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color image systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts, the term pixel is used to refer to a single scalar element of a multi-component representation, while in others the term may refer to the entire set of such component intensities for a spatial position. In color systems that use chroma subsampling, the multi-component concept of a pixel can become difficult to apply, since the intensity measures for the different color components correspond to different spatial areas in such a representation.

Examples of pixel in a Sentence

1. Jeff Meyer:

   pixel, n.: A mischievous, magical spirit associated with screen displays. The computer industry has frequently borrowed from mythology: Witness the sprites in computer graphics, the demons in artificial intelligence, and the trolls in the marketing department.

2. Tuong Nguyen:

   So the Pixel phones will likely continue to serve as a paradigm for OEMs [manufacturers].

3. David McQueen:

   Google never intended Google Pixel to be Google Pixel, the idea was that they would use the Pixel devices to showcase the Google Android ecosystem, demonstrating to their partners what could be done with top-end hardware and the latest Android software.

4. Joaquin Quinonero Candela:

   It’s somewhere in some photo [collection] a friend of mine took but in a few years I will have forgotten who took it, we’re doing research on cracking the image open and understanding it at the individual pixel level. This is called image segmentation. We’re building the ability to understand the individual objects that compose an image.

5. Arnau Garcia:

   Right now natural parks have two big problems, the first one of them is to detect rhinos and non-authorized people in the area. That has been done with helicopters and planes up until now, but that is very expensive. In addition, you cannot see people who hide under trees from a plane. We solve this with thermal cameras. We use a drone that carries that kind of camera and looks over that area or those places suspected of having this kind of problem and it detects hot points. Like we see here. This shows people. Every pixel has a different color depending on how hot it is. This is placed on the drone, that takes a picture and reports directly to the ranger.
