openjpeg, branch t1_optim_attempt_refpass_4_at_context16 Fork of openjpeg library for JPEG2000 encoding and decoding https://git.carlh.net/cgit/openjpeg/atom?h=t1_optim_attempt_refpass_4_at_context16 2017-05-22T11:27:27Z T1: (failed) optimization attempt for low bit planes in refpass (#932) 2017-05-22T11:27:27Z Even Rouault even.rouault@spatialys.com 2017-05-22T11:27:27Z urn:sha1:dcf013db288db8712010648d378a293bb91a0eb7 In the lowest bit plane in 6 to 8% of the cases, the 4 samples in a column in the zig-zag pattern are in context 16 of the refpass. So let's add a dedicated function for this. However the (best) timings show that it is actually slower. With this special case: 50205 ms vs 49570 ms originally on MAPA_005.jp2 reencoded with default options. MQC: remove disabled MQC_PERF_OPT mode, which brings no performance improvements (see #923) 2017-05-15T12:11:47Z Even Rouault even.rouault@spatialys.com 2017-05-15T12:11:47Z urn:sha1:83d7a6d4a44833e78321bfd367dc0f822a8d0945 Add comments about non successfull attempt of implementing alternate INITDEC, DECODE and BYTEIN procedures (refs #921) 2017-05-15T12:09:51Z Even Rouault even.rouault@spatialys.com 2017-05-15T12:09:51Z urn:sha1:4431fa72657b6c4a92c3cf29cfc5c8df69424a0e Merge pull request #926 from rouault/reformat_h_files 2017-05-15T11:08:03Z Even Rouault even.rouault@mines-paris.org 2017-05-15T11:08:03Z urn:sha1:f7a126af61877cd4623327142521d82a0c19430d Reformat: apply reformattin on .h files (#128) Reformat: apply reformattin on .h files (#128) 2017-05-15T10:21:30Z Even Rouault even.rouault@spatialys.com 2017-05-15T10:21:30Z urn:sha1:3c2972f924857016bb454201c7e92f25de9105ee Merge pull request #919 from rouault/reformat 2017-05-15T10:09:45Z Even Rouault even.rouault@mines-paris.org 2017-05-15T10:09:45Z urn:sha1:28d2eabca79d06378843d1e94fecfb4a5e22178d Add mechanisms to reformat and check code style, and reformat whole codebase (#128) perf_test.py: implement -i option 2017-05-11T18:18:42Z Even Rouault even.rouault@spatialys.com 2017-05-11T18:18:42Z urn:sha1:0ecac46a1db911cbe340c4467000e91cea82c96d astyle.options: use non deprecated option name 2017-05-11T09:21:37Z Even Rouault even.rouault@spatialys.com 2017-05-11T09:21:37Z urn:sha1:cde210be392d60fbcd8a3e7cacfa62660a95e8d9 Reformat whole codebase with astyle.options (#128) 2017-05-09T18:46:20Z Even Rouault even.rouault@spatialys.com 2017-05-09T13:44:46Z urn:sha1:563bd8499e63db976ca8358216138647593354bc Add mechanisms to reformant and check code style (#128) 2017-05-09T18:46:16Z Even Rouault even.rouault@spatialys.com 2017-05-09T13:28:09Z urn:sha1:d4e54e9f35d532062533f1d369c159810b01d224 Use an internal version of astyle (astyle 3.0).
