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. 2007-11-13T17:35:12Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-11-13T17:35:12Z urn:sha1:dbeebe72b9d35f6ff807c21c7f217b569fa894f6 Patch suggested by Callum Lerwick <seg@haxxed.com>: "This makes the t1 data arrays dynamic, which greatly reduces cache thrashing. Also, some minor cleanup to prevent unnecessary casts" 2007-05-22T13:14:13Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-05-22T13:14:13Z urn:sha1:8be8111008f87f643cafde4d5204d8146786b140 Patch suggested by Callum Lerwick <seg@haxxed.com>: "This changes the flag code in t1 to use a flag_t type, which can then be changed to reduce RAM usage. It is now typedef to a short." 2007-05-21T12:50:03Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-05-21T12:50:03Z urn:sha1:7d06d7fb5db82318686bad0b99951d6d612f6cca Patch suggested by Callum Lerwick <seg@haxxed.com>: "This patch makes the t1 LUTs static. I actually intend this as a prelude to possibly eliminating some or all of the LUTs entirely." 2007-05-21T09:44:10Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-05-21T09:44:10Z urn:sha1:e0ee9becb44885136be01e15fa4feaf75478b19b Digital cinema compliance for 4K chosen by "-cinema4K" option. Modification in image_to_j2k.c. 2007-04-04T13:40:32Z Parvatha Elangovan p.elangovan@intopix.com 2007-04-04T13:40:32Z urn:sha1:dd18811600365adc935a5f72d985bac43a01377f Bit rate limitation for each color component. Modification in image_to_j2k.c, t2.c. Modified and tested Progression order change "-POC" option. Modification in image_to_j2k.c, j2k.c, pi.c. Function j2k_check_poc_val() to check for possible loss of packets in case of wrong POC declaration. Modification in j2k.c. Structure T2_MODE. This tells if the t2_encode_packets() is called during Threshold calculation or in Final pass. Modification in j2k.h, tcd.c Modification of the context numbers, to reflect what has been specified in standard. 2007-01-23T11:41:16Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-01-23T11:41:16Z urn:sha1:521b9bef33551960086a5abae0f544640faf5bfc Copyright update 2007-01-15T09:55:40Z Francois-Olivier Devaux fodevaux@users.noreply.github.com 2007-01-15T09:55:40Z urn:sha1:ed3aec55fdc1a598981823d7e40d078d5b08610b OpenJPEG version 1.1 2005-12-08T09:38:47Z Antonin Descampe antonin@gmail.com 2005-12-08T09:38:47Z urn:sha1:95bc884365deb41c357583874c23d82eac7cad2d openjpeg version 1.0 (previous version still available with tag opj0-97) 2005-12-02T13:34:15Z Antonin Descampe antonin@gmail.com 2005-12-02T13:34:15Z urn:sha1:f61cda9b7d83e0202cbaa15bac45d358e9b3652e
