33 : | Isibaar | 3 | * Modifications: |
34 : | * | ||
35 : | suxen_drol | 152 | * 01.05.2002 updated MotionEstimationBVOP |
36 : | suxen_drol | 136 | * 25.04.2002 partial prevMB conversion |
37 : | chenm001 | 132 | * 22.04.2002 remove some compile warning by chenm001 <chenm001@163.com> |
38 : | * 14.04.2002 added MotionEstimationBVOP() | ||
39 : | chl | 96 | * 02.04.2002 add EPZS(^2) as ME algorithm, use PMV_USESQUARES to choose between |
40 : | * EPZS and EPZS^2 | ||
41 : | Isibaar | 3 | * 08.02.2002 split up PMVfast into three routines: PMVFast, PMVFast_MainLoop |
42 : | * PMVFast_Refine to support multiple searches with different start points | ||
43 : | edgomez | 78 | * 07.01.2002 uv-block-based interpolation |
44 : | Isibaar | 3 | * 06.01.2002 INTER/INTRA-decision is now done before any SEARCH8 (speedup) |
45 : | edgomez | 78 | * changed INTER_BIAS to 150 (as suggested by suxen_drol) |
46 : | * removed halfpel refinement step in PMVfastSearch8 + quality=5 | ||
47 : | * added new quality mode = 6 which performs halfpel refinement | ||
48 : | * filesize difference between quality 5 and 6 is smaller than 1% | ||
49 : | Isibaar | 3 | * (Isibaar) |
50 : | * 31.12.2001 PMVfastSearch16 and PMVfastSearch8 (gruel) | ||
51 : | edgomez | 78 | * 30.12.2001 get_range/MotionSearchX simplified; blue/green bug fix |
52 : | * 22.12.2001 commented best_point==99 check | ||
53 : | * 19.12.2001 modified get_range (purple bug fix) | ||
54 : | Isibaar | 3 | * 15.12.2001 moved pmv displacement from mbprediction |
55 : | * 02.12.2001 motion estimation/compensation split (Isibaar) | ||
56 : | edgomez | 78 | * 16.11.2001 rewrote/tweaked search algorithms; pross@cs.rmit.edu.au |
57 : | Isibaar | 3 | * 10.11.2001 support for sad16/sad8 functions |
58 : | * 28.08.2001 reactivated MODE_INTER4V for EXT_MODE | ||
59 : | * 24.08.2001 removed MODE_INTER4V_Q, disabled MODE_INTER4V for EXT_MODE | ||
60 : | edgomez | 78 | * 22.08.2001 added MODE_INTER4V_Q |
61 : | Isibaar | 3 | * 20.08.2001 added pragma to get rid of internal compiler error with VC6 |
62 : | * idea by Cyril. Thanks. | ||
