Advanced Digital Video Processing
The concept of an image being created by superposition of object layers has been used by photograph editors for many many years. Adobe Photoshop has been using this idea since 1989. In 1994, Wang and Adelson presented an article in which they gave serious credence to the idea that each frame in an image sequence can be constructed by layers of object planes. This is a much more realistic idea. ...
متن کاملIntroduction to Digital Video Processing Image and Video Processing
A video signal is the term used to describe any sequence of time varying images. A still image is a spatial distribution of intensities that remain constant with time while a time varying image has a spatial intensity distribution that varies with time. Movies (films) and television are both examples of video signals as are the signals that drive computer monitor, laptop and PDA displays. It is...

متن کاملApplying FIR and IIR Digital Filters over Video Image Processing
Digital Video is a stream of still images called frames, which are moved such that it gives an illusion of dynamics of the objects present in the image. Video image processing is basically processing of frames and updating frames with a minimum frame rate of 16 per second to give an illusion of motion picture. The objective of the research is all about the development of high throughput image p...
متن کاملObject - Based Digital Video Processing Using 2 - D Meshes
This thesis addresses extraction and tracking of video objects for object-based representation and manipulations of synthetic and natural digital video. Object-based video representation has gained a signi cant momentum by recent developments in multimedia computing, and has emerged as a major area of research. Many multimedia applications, such as bit-stream editing, interactive TV, and digita...
