|
|
* Dr. Tim Ferguson, 2001.
|
|
* For more details on the algorithm:
|
|
* http://www.csse.monash.edu.au/~timf/videocodec.html
|
|
*
|
|
* This is basically a vector quantiser with adaptive vector density. The
|
|
* frame is segmented into 4x4 pixel blocks, and each block is coded using
|
|
* either 1 or 4 vectors.
|
|
*
|
|
* There are still some issues with this code yet to be resolved. In
|
|
* particular with decoding in the strip boundaries. However, I have not
|
|
* yet found a sequence it doesn't work on. Ill keep trying :)
|
|
