3 |
* Modifications: |
* XVID MPEG-4 VIDEO CODEC |
4 |
|
* motion estimation |
5 |
* |
* |
6 |
* 02.04.2002 add EPZS(^2) as ME algorithm, use PMV_USESQUARES to choose between |
* This program is an implementation of a part of one or more MPEG-4 |
7 |
* EPZS and EPZS^2 |
* Video tools as specified in ISO/IEC 14496-2 standard. Those intending |
8 |
* 08.02.2002 split up PMVfast into three routines: PMVFast, PMVFast_MainLoop |
* to use this software module in hardware or software products are |
9 |
* PMVFast_Refine to support multiple searches with different start points |
* advised that its use may infringe existing patents or copyrights, and |
10 |
* 07.01.2002 uv-block-based interpolation |
* any such use would be at such party's own risk. The original |
11 |
* 06.01.2002 INTER/INTRA-decision is now done before any SEARCH8 (speedup) |
* developer of this software module and his/her company, and subsequent |
12 |
* changed INTER_BIAS to 150 (as suggested by suxen_drol) |
* editors and their companies, will have no liability for use of this |
13 |
* removed halfpel refinement step in PMVfastSearch8 + quality=5 |
* software or modifications or derivatives thereof. |
|
* added new quality mode = 6 which performs halfpel refinement |
|
|
* filesize difference between quality 5 and 6 is smaller than 1% |
|
|
* (Isibaar) |
|
|
* 31.12.2001 PMVfastSearch16 and PMVfastSearch8 (gruel) |
|
|
* 30.12.2001 get_range/MotionSearchX simplified; blue/green bug fix |
|
|
* 22.12.2001 commented best_point==99 check |
|
|
* 19.12.2001 modified get_range (purple bug fix) |
|
|
* 15.12.2001 moved pmv displacement from mbprediction |
|
|
* 02.12.2001 motion estimation/compensation split (Isibaar) |
|
|
* 16.11.2001 rewrote/tweaked search algorithms; pross@cs.rmit.edu.au |
|
|
* 10.11.2001 support for sad16/sad8 functions |
|
|
* 28.08.2001 reactivated MODE_INTER4V for EXT_MODE |
|
|
* 24.08.2001 removed MODE_INTER4V_Q, disabled MODE_INTER4V for EXT_MODE |
|
|
* 22.08.2001 added MODE_INTER4V_Q |
|
|
* 20.08.2001 added pragma to get rid of internal compiler error with VC6 |
|
|
* idea by Cyril. Thanks. |
