Increase the partition and acskip thresholds for temporal
enhancement layers.
~1-2% speedup, with negligible loss in quality.
Change-Id: Id527398a05855298ad9ddac10ada972482415627
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
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.

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
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
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
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
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
If enabled denoiser will only denoise the top spatial layer for now.
Added unittest for SVC with denoising.
Change-Id: Ifa373771c4ecfa208615eb163cc38f1c22c6664b
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
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
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
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
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
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
More aggresive on avoiding denoising on skin.
May supplement this later by adding condtion onn consec_zeromv.
Change-Id: Ied92b332f9b24e821d2009f81d1565758588d9a5
Add function to compute skin map for a given block, as its
used in several places (cyclic refresh, noise estimation, and denoising).
Change-Id: Ied622908df43b6927f7fafc6c019d1867f2a24eb
Under certain denoising conditons, check for re-evaluation of
zero_last mode if best mode was golden reference.
Change-Id: Ic6cdfd175eef2f7d68606300c7173ab6654b3f6e
For denoising, and for noise level above threshold, re-evaluate
ZEROMV for mode selection after denoising.
Current change only does this check if selected best mode (before denoising)
was intra.
Change-Id: I4b1435b68d26c78f7597b995ee7bff0ddd5f9511
Source noise level estimate is also useful for
setting variance encoder parameters (variance thresholds,
qp-delta, mode selection, etc), so allow it to be used also
if denoising is not on.
Change-Id: I4fe23d47607b4e17a35287057f489c29114beed1
Adjust variance threshold, delta-qp, and intra penalty cost,
based on estimated noise level in source.
Replace denoising_on with a level value=L/M/H.
Change-Id: I0c017dae75a5d897367d2c42dec26f2f37e447c1
Periodically estiamte noise level in source, and only denoise
if estimated noise level is above threshold.
Change-Id: I54f967b3003b0c14d0b1d3dc83cb82ce8cc2d381
The artifact occurs periodically when VP9 denoiser is on and
refresh_golden_frame happen. When refresh_golden_frame happen,
we should copy the frame buffer instead of swapping the pointers.
Change-Id: Ib3204c4b04db28ecf439c6d9e61f3d146f04196d
Temporary fix to denoiser when dynamic resizing is on.
-Reallocate denoiser buffers on resized frame.
-Force golden update on resized frame.
-Don't denoise resized frame, and copy source into denoised buffers.
