2014-10-06Add SSE2 code and unit test for VP9 denoiser.JackyChen
This SSE2 is based on VP8 denoiser's SSE2 code. In VP8, there are only 16x16 blocks in denoiser, while in VP9, there are 13 different block sizes. By adding this SSE2 code, the improvement of encoder speed is around 20%(using C code vs using SSE2 code), vary for different clips. The unit test for VP9 denoiser is to confirm that the SSE2 code is bit-exact with the C code. The unit test covers all block size. Change-Id: Ic8d8ac26db4ea40a5f146b5678a065af07eaaa3d
2014-09-29Fix a bug in calculating delta in VP9 denoiser.JackyChen
When calculating delta in VP8 denoiser, since the block size is fixed to 16x16, the divisor is 256, which is the number of the pixel. But in VP9, the block size varies, the divisor should correspond to the block size. Change-Id: Ibdc1e5d23ba8c788b0d0dc6d406bcdfc34c1b142
2014-09-19Remove mi_grid_* structures.hkuang
mi_grid_* are arrays of pointer to pointer. They save the pointers that point to the MIs in cm->mi. But they are unnecessary and complicated. The original goal was to remove MODE_INFO_t copy. But with an extra MODE_INFO_t pointer inside MODE_INFO_t, same goal could be achieved. This commit totally removes the mi_grid_* structures. But there are still many dummy MODE_INFO_t inside cm->mi which are a waste of memory. Next commit will do on-demand MODE_INFO_t allocation in order to save these memories.

2014-09-10Fix the bug which made VP8 denoiser not bit-exact between C code and SSE code.JackyChen
This issue is found when the denoising mode is set to kDenoiserOnYUVAggressive. Updated the C code to make it the same with SSE version. I also changed several lines in VP9 denoiser for the code style. Change-Id: I640d48cf946fe8c6a400e6e252107501d1e226d3
2014-09-04Map motion magnitude in VP9 denoiser.JackyChen
This is to keep the same with VP8 denoiser. If motion magnitude is small, make denoiser more aggressive. Change-Id: I942a6e2f2ed9aec6f0c4c1f9e5fa47066cadcc0c
2014-09-04Update the condition when COPY_BLOCK is chosen.JackyChen
The change is just to keep the condition the same with VP8. Change-Id: I9662b40996126605945dd853c0cbe8916c1ce578
2014-09-04Fix a bug in VP9 denoiser.JackyChen
When the first try of denoising turns out to be too much, we will use a softer filter by adopting an adjustment to make the result closer to original pixel (as in VP8 denoiser). The old code made the adjustment in the wrong direction. Change-Id: I84e28fa9e01eef47c5a37d5a2e6d3d378a06786b
2014-09-02Adds config opt for highbitdepth + misc. vpxDeb Mukherjee
Adds config parameter vp9_highbitdepth, to support highbitdepth profiles. Also includes most vpx level high bit-depth functions. However encode/decode in the highbitdepth profiles will not work until the rest of the code is in place. Change-Id: I34c53b253c38873611057a6cbc89a1361b8985a6

2014-07-18VP9 denoiser fix: ref frames now updated properlyTim Kopp
The ALT_REF_FRAME is now updated in the case of a KEY_FRAME in the VP9 denoiser. Change-Id: Idf9a9772706f50e774fb240afcc01db38841043c
2014-07-15VP9 Denoiser denoises after mode/bsize searchTim Kopp
In vp8, statistics are collected about the different modes as they are searched. This process is more complicated due to the variable block size. Fields were added to the PICM_MODE_CONTEXT struct to hold this information for each point in the search. The information is then taken from the appropriate part of the tree during denoising.

2014-07-08Vp9 denoiser MC bugfixTim Kopp
In the previous version, only certain buffers in the macroblockd were saved and the restored. In this version, all of the buffers are saved and restored. The code was then rolled into a loop for readability. Also contains a tiny fix for when the -DOUTPUT_YUV_DENOISED flag is used. Change-Id: Id925ef8b3fa122ae88acfa1d9a1e4df45df83518
2014-07-02VP9 denoiser implemented FILTER_BLOCK caseTim Kopp
Renamed updating_running_avg() to filter(). Extended function with the rest of the filter procedure. Made all of the empirically-determined constants used in VP8 into functions so they can be tweaked more easily. Change-Id: I41730c8c92370c76885950a43742347477ca4e7e
2014-07-02VP9 denoising enabled by noise_sensitivity paramTim Kopp
As in VP8. Currently, this parameter is set with the VP8E_SET_NOISE_SENSITIVITY flag. The flag was not renamed so that we don't break the interface for webrtc. This should probably be changed at some point in the future. Change-Id: Ic73fcb0dde9d1d019e9d042050b617333ac65472
