A scalable off-line MPEG-2 video encoding scheme.. - Ahmad, Akramullah.. (2000) (Correct)
.... in applications like digital library or production systems which require encoding a video sequence and storing it on a CD ROM or DVD (Digital Versatile Disk) There are two approaches to performing video compression: hardware based [1] 23] and software based [2] 3] 4] 7] 10] 11] [19], 20] 22] 24] Both approaches have their own advantages and disadvantages. A hardware approach uses a special purpose architecture, and its advantages include the ease of use and high compression speed. However, dedicated hardware is less flexible and can become obsolete. Furthermore, ....

Compactly-Encoded Optical Flow Fields For Motion-Compensated.. - Krishnamurthy (1997) (Correct)
....coefficients at a particular level j. The interactions within this level are local, due to the compact support of the basis functions. Therefore, we can simultaneously update several coefficients that do not directly interact with each other. This is similar to the image coding schemes found in [94, 95], and is suitable for implementation on a single instructionmultiple data (SIMD) machine. In particular, the algorithms were implemented on two MasPar MP 1 computers, one having 16K processors (at Bellcore, Morristown, NJ) and the other having 2K processors (at Rensselaer Polytechnic Institute, ....

The pixels within each group may be updated simultaneously, and the L groups are visited in succession. For L = 2, this technique is known as red black Gauss Seidel [23, 28].
