| 2017-06-21 | IDWT 5x3: generalize SSE2 version for AVX2 | Even Rouault | |
| Thanks to our macros that abstract SSE use, the functions can use AVX2 when available (at compile time) This brings an extra 23% speed improvement on bench_dwt in 64bit builds with AVX2 compared to SSE2. | |||
| 2017-06-21 | dwt.c: small cleanup | Even Rouault | |
| 2017-06-20 | Enable __SSE__ / __SSE2__ with Visual Studio | Even Rouault | |
| 2017-06-20 | Improve performance of inverse DWT 5x3 (#953) | Even Rouault | |
| * Use single-pass lifting inverse wavelet transform. * For vertical pass, use SSE2 when available so as to process 8 columns in parallel. This is the most beneficial improvement, since the vertical pass involves a lot of cache trashing. With the bench_dwt utility with default arguments (16383x16383 image), time goes from 4.064 s to 1.212 s. | |||
| 2017-06-20 | Add bench_dwt program (compiled only if BUILD_BENCH_DWT=ON) | Even Rouault | |
| 2017-06-17 | Remove OPJ_NOSANITIZE in opj_bio_read() and opj_bio_write() (#761) | Even Rouault | |
| Commit 29313eb5 introduced those flags to avoid issues with -fsanitize=unsigned-integer-overflow However it is better just to rewrite the loop to avoid such condition to occur. | |||

| (small optimization) | |||
| 2017-06-12 | Encoder: fix packet writing of empty sub-bands (#891, #892) | Even Rouault | |
| There are situations where, given a tile size, at a resolution level, there are sub-bands with x0==x1 or y0==y1, that consequently don't have any valid codeblocks, but the other sub-bands may be non-empty. Given that we recycle the memory from one tile to another one, those ghost codeblocks might be non-0 and thus candidate for packet inclusion. | |||
| 2017-06-09 | T1: fix BYPASS/LAZY, TERMALL/RESTART and PTERM/ERTERM encoding modes. (#674)fix_bypass_pterm_termall | Even Rouault | |
| There were a number of defects regarding when and how the termination of passes had to done and the computation of their rate. | |||
| 2017-06-02 | opj_t1_dec_sigpass_raw/opj_t1_dec_refpass_raw: harmonize style with mqc methods | Even Rouault | |
| 2017-06-02 | MQC/RAW decoder: use an artificial 0xFF 0xFF terminating marker. | Even Rouault | |
| This saves comparing the current pointer with the end of buffer pointer. This results at least in tiny speed improvement for raw decoding, and smaller code size for MQC as well. This kills the remains of the raw.h/.c files that were only used for decoding. Encoding using the mqc structure already. | |||
| 2017-06-02 | Fix documentation of opj_t1_decode_cblks() | Even Rouault | |
| 2017-06-02 | Simplify VSC handling: instead of masking out bits when reading the 4th row. | Even Rouault | |
