2019-03-06vp9-denoiser: Bias to last for golden long termMarco Paniconi
If golden referene is selected as long-term reference, bias the denoiser filter to use last reference. Fixes visual artifact. And reduce the thresh_svc_golden, which was used to reduce the artifact occurrence. Change-Id: I08f24160ca11bd8f5f70acaefe989d5f92988132
2019-02-27vp9-rtc: Change init level of denoiser & noise levelMarco Paniconi
Change to init/reset level of the denoiser from kDenLow to kDenMedium, and the init noise level to kLow. This affects the denoiser level during the initialization stage of the noise estimation. Improves denoising for noisy content during init stage of noise estimation, with little effect for low noise/clean content. Change-Id: I247a17b0f01f646fc2e91a4a070ad69bdb788cae

2018-12-04vp9: force refresh of long term ref when denoiser reset.Jerome Jiang
This will allocate extra frame buffer if long term temporal reference is used and denoiser is enabled on non-key frame. Add test. Change-Id: I0e8d1fdb9a2d697a8eed7fe6206bcb362e69f1c8
2018-11-28vp9 denoiser: force copy block when last not a reference.Jerome Jiang
Last reference doesn't always exist when SVC layers changed dynamically. When last is not a reference for current layer, copy block directly on denoiser. Change-Id: I9d98c4d6fdcfa25ba707db3333712761b5cf9ab8

2018-06-29vp9: copy source on sync frame in denoiser.Jerome Jiang
Refresh all denoiser buffers on sync frame. Add sync frame test with denoiser enabled. Change-Id: I562a5ef5614b92a97565e6181a79eda51d9aeb99
2018-06-11vp9 svc: Denoise golden when it's a temporal ref.Jerome Jiang
When golden was the inter-layer reference, a block that selected the golden ref would not be denoised. But when golden is used as a second temporal reference then we should denoise blocks that select the golden reference. This changes allows for that.

2017-12-11vp9 svc: Allow denoising next to highest resolution.Jerome Jiang
Denoise 2 spatial layes at most. Add noise sensitivity level 2 for vp9 such that applications can control whether to denoise the second highest spatial layer. Add tests to cover this case. Change-Id: Ic327d14b29adeba3f0dae547629f43b98d22997f

2017-08-15Clean up writing YUV files for debug purpose.Jerome Jiang
Change legacy vp8/9_write_yuv_frame to vpx_write_yuv_files. Delete some flags that can be enabled during build. To enable writing denoised YUV, use the following command line: CFLAGS='-DOUTPUT_YUV_DENOISED' ./configure --enable-vp9-temporal-denoising For skinmap, use CFLAGS='-DOUTPUT_YUV_SKINMAP' Change-Id: I236974ac8b3cf279d20c4dc7f6162d8b480b6528

2017-08-10vp9 SVC: Fix the denoiser frame buffer management.Jerome Jiang
Change the denoiser frame buffer management for SVC to more generally handle the layer patterns in SVC (where last is not always refreshed). This change is only for SVC with denoising and is bitexact. Change-Id: Ic2b146a924cdf6e7114609158afa3d4880fe3fae
2017-07-30vp9: Fix denoising condition when pickmode partition is used.Marco
When the superblock partition is based on the nonrd-pickmode, we need to avoid the denoising. Current condition was based on the speed level. This change is to make the condition at the superblock level, as the switch in partitioning may be done at sb level based on source_sad (e.g., in speed 6). Change-Id: I12ece4f60b93ed34ee65ff2d6cdce1213c36de04
2017-07-18vp9: Allocate alt-ref in denoiser for SVC.Jerome Jiang
When SVC is used, allocate alt-ref in denoiser. Change-Id: I1b17221b55b9444cd23b97d481b54ff8d296d857
2017-07-11vp9: Fix to SVC and denoising for fixed pattern case.Marco
For fixed pattern SVC: keep track of denoised last_frame buffer for base temporal layer, and if alt_ref is updated on middle/upper temporal layers, force an update to denoised last_frame buffer. This allows for improved denoising on top temporal layers. Change-Id: Icbd08566027d4d2eabc024d3b7a0d959d2f8c18b
2017-07-10vp9: Remove alt-ref from denoiser.Jerome Jiang
Denoiser is used in real-time mode which does not use alt-ref. Reduce memory usage when denoiser is enabled. Change-Id: I54ba3bcaeeb1818bbdf718ef90e97d4897ff793d
2017-05-11vp9: SVC: Increase the partiiton and acskip thresholdsMarco
Increase the partition and acskip thresholds for temporal enhancement layers. ~1-2% speedup, with negligible loss in quality. Change-Id: Id527398a05855298ad9ddac10ada972482415627
2017-05-10vp9: Fix ubsan failure in denoiser.Jerome Jiang

2017-04-24vp9; Reduce artifact in non-rd pickmode for lighting changes.Marco
Add a low-variance high-sumdiff to the superblock content state and use it to limit the mv and bias some decisions in non-rd pickmode. Only affects speed >= 6. Reduces artifact for lighting changes. Small/no difference in metrics on RTC set. Change-Id: Ic84b2379fe0ae3fa71ae826ee6bae3eaf551a25b
2017-04-06vp9; Move the denoising condition for speed 5.Marco
Move the condition for effectively disabling the denoising for speed 5 into the vp9_denoiser_denoise(). This is cleaner, and also moving the condition into vp9_denoiser_denoise will keep the denoiser buffer updated with the current source. This allows for more consistent behavior if speed is changed midstream. Change-Id: Ia001f591c56e454bf724c3ae73c024badb183ef8
2017-03-31vp9: SVC: Fix issue with artifact for svc-denoising.Marco
Issue/bug happens for denoising with spatial layers, where the golden (spatial) reference is used in pickmode, but denoising is only done wrt to last (temporal). Fix is to make sure set_ref_ptrs is set before build predictors in denoiser. Change-Id: I793cf441341edf7c4a88b8ab1e1b22b3cb0eb508
2017-03-29vp9: SVC: fix to allow output of denoised result.Marco

2017-03-15vp9: Fix some issues with denoiser and SVC.Marco
Fix the update of the denoiser buffer when the base spatial layer is a key frame. And allow for better/lower QP on high spatial layers when their base layer is key frame. Change-Id: I96b2426f1eaa43b8b8d4c31a68b0c6d68c3024a2
2017-02-21vp9: Incorporate source sum_diff into non-rd partition thresholds.Marco
Increase the variance partition thresholds for superblocks that have low sum-diff (from source analysis prior to encoding frame). Use it for now only for speed >= 7 or for denoising on. Small change on metrics for rtc set: less than ~0.1 avgPNSR decrease on RTC set, for both speed 7 and 8. Change-Id: I38325046ebd5f371f51d6e91233d68ff73561af1
2017-02-07vp9: Denoiser speed-up: increase partition and ac skip thresholds.Marco
Add factor to increase varianace partition and ac skip thresholds, under certain conditions (noise level and sum_diff), to increase denoiser speed. Change-Id: I7671140ef3598bf5f114a72623d68792bcd7b77b
2017-01-25vp9-denoiser: Modify skip denoising condition for small blocks.Marco
Skip denoising for blocks < 16x16, and for block = 16x16 skip denoising for low noise levels and width > 480 for now. Allow for some speed-up in denoiser. Change-Id: Ib46cefe4741962d145fa08775defea3a9c928567
2017-01-10vp9: Make the denoiser work with spatial SVC.Marco
If enabled denoiser will only denoise the top spatial layer for now. Added unittest for SVC with denoising. Change-Id: Ifa373771c4ecfa208615eb163cc38f1c22c6664b

2016-04-25vp9: Fix a bug where best_sse_mv is not set properly.JackyChen
In VP9 internal denoiser, motion magnitude is computed from best_sse_mv, which should be set to 0 at the begining. This bug may cause visual aritifact in denoiser. Also, delete two improper comments. Change-Id: I8710d2acba23320bc85cf72af17d65245c19438b
2016-04-25vp9-denoiser: Bugfix and some adjustments for high noise case.Marco
Need to check that sse for non-zero mv has been set for the current block (i.e., check that nonzero-mv is tested as a mode, so newmv_sse != UINT_MAX) before forcing to not use zero-mv for denoising. Also increase some thresholds (sse and sse_diff) for high noise case, and use shift operaton instead of multiplication on a threshold computation. Change-Id: Iae7339475d57240316b7fa8b887c4ee3c0d0dbec

2016-04-22vp9: Move consec_zero_mv from cyclic refresh to cpi struct.Marco
So it can be used even with aq-mode=3 not enabled. Also cleans up some code in the places where its used. No change in behavior. Change-Id: Ib6b265308dbd483f691200da9a0be4da4b380dbc
2016-04-04vp9-denoiser: Avoid copy-block when denoising is at LowLow level.Marco
Avoid copy-block when denoising is at LowLow level (i.e., no denoising is done). Instead, don't enter denoiser at all, and when level goes back up over kLowLow do a reset in denoiser. Change-Id: I0544adf58f4dd51ecc4a4607fcb0353bfbbb7a59

2016-04-04vp9-noise estimation: Increase threshold for Low-level.Marco
This make it more likely clean/low-noise content will be set as LowLow, and hence no denoising will be done. Also set early exit on denoising for small blocks. Change-Id: I4a72bba3e6c5e2d523d304c39deacc9c39bf216c
2016-04-04vp9-denoiser. Code cleanup and bugfix.Marco
Some cleanup and bugfix: pass mi_row/mi_col (not mv_col/mv_row) to build_inter_predictors. This only affects case where the frame is resized, but since denoising is not done on resized frames, the fix has not effect currently. Change-Id: I36617a7f0b43b6f49976745f15d400977e6ffa46
