Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data.
Composite image showing JPG and PNG image compression. Left side of the image is from a low-quality JPEG image, showing lossy artefacts; the right side is from a PNG image. In information technology , lossy compression or irreversible compression is the class of data compression methods that uses inexact approximations and partial data ...
Three types of pictures (or frames) are used in video compression: I, P, and B frames.. An I‑frame (intra-coded picture) is a complete image, like a JPG or BMP image file.. A P‑frame (Predicted picture) holds only the changes in the image from a previous frame.

Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general-purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay.
The effect: A two-loss Penn State would have fallen out of the Big Ten championship and, later, possibly out of the CFP entirely. Nov. 23, Ole Miss at Florida. The play: Pick one: the interception ...
.img is also a planar bitmap graphics file using simple run-length encoding, originating with Digital Research's GEM.It was commonly used on the Atari ST line of home computers, but also with some GEM-based PC software such as Corel Ventura or Timeworks Publisher.
DeVito's 6.2 YPA is close enough to Jones' 6.5, but New York’s new QB owns a 17.2% sack rate and a lower aDOT.DeVito averaged only 172 passing yards and 0.9 TDs in five games where he played at ...
