A set of user interface guidelines created by the Open Software Foundation (www.opengroup.org) that specify how an application should look and feel, covering issues like the placement of title bars and menus. It is used on more than 200 hardware and software platforms and has become the standard graphical user interface (GUI ) for UNIX.
JPEG stands for the Joint Photographic Experts Group standard, a standard for storing and compressing digital images. Motion-JPEG extends this standard by supporting videos. In motion-JPEG, each frame in the video is stored with the JPEG format.
- motion compensation and prediction
In video editing motion compensation provides a prediction for the macroblock. When prediction is applied, the DCT is applied to conform to the prediction errors instead of to image samples. Good motion compensation prediction will result in a lower bit rate and still maintain decent quality. Also called motion compensated prediction.
- motion detection
In video surveillance, motion detection refers to the capability of the surveillance system to detect motion and capture the events. Motion detection is usually a software-based monitoring algorithm which, when it detects motions will signal the surveillance camera to begin capturing the event. Also called activity detection. An advanced motion detection surveillance system can analyze […]
- motion estimation
In video editing motion estimation is a type of video compression scheme. The motion estimation process is done by the coder to find the motion vector pointing to the best prediction macroblock in a reference frame or field. For compression redundancy between adjacent frames can be exploited where a frame is selected as a reference […]
- motion vector
In video editing motion vectors are used to compress video by storing the changes to an image from one frame to the next. The process is a bi-dimensional pointer that communicates to the decoder how much left or right and up or down, the prediction macroblock is located from the position of the macroblock in […]
