Francois-Olivier Devaux 627f484bce Significant optimizations of MCT, DWT, MQ and T1 modules by Peter Wimmer (thanks Peter) 2010-04-08 17:22:58 +00:00
Antonin Descampe 847b082b64 changed variables names alpha, beta, gamma, delta in dwt.c to avoid re-declarations on Macosx 2007-12-19 14:45:35 +00:00
Francois-Olivier Devaux dbeebe72b9 Patch by Dzonatas and Callum Lerwick. Fp/vectorization patch which basically converts most of the irreversible decode codepath to floating point, eliminating a few rounds of int/fp conversion, resulting in a vast performance improvement, and an increase in accuracy. 2007-11-13 17:35:12 +00:00
Francois-Olivier Devaux 4bb067642f Patches from Callum Lewick: Fixed some spelling errors in dwt.c. 2007-11-08 14:29:39 +00:00
Francois-Olivier Devaux 4b60f17bba Patch from Callum Lewick. Fixed dwt.c where an alignment in buffer was problematic under x86_64. 2007-09-27 12:20:12 +00:00
Francois-Olivier Devaux 0930d9886b fix.h, dwt.c and t1.c optimized. Thanks a lot to Dzonatas <dzonatas at dzonux.net> and Callum Lerwick <seg at haxxed.com> for these great patches ! 2007-04-05 14:24:19 +00:00

Antonin Descampe 8f3bd54c3d Changes proposed by Mathieu Malaterre from the GDCM project... Thanks a lot Mathieu
- '//' replaced by '/* */'
- inclusion of int.h in int.c
- inclusion of j2k.h in int.h in order to export symbols
- adding (void) var when a variable is declared but not used
- some explicit cast
- CLOCKS_PER_SEC is declared as float in bcc55, so there is a need to cast it to int for the modulo operation
- some variables changed from float -> double
