2013-05-30Patch to remove implicit segmentation.Paul Wilkins
This patch removes the implicit segmentation experiment from the code base as the benefits were still unproven as of the bitstream deadline. Change-Id: I273b99d8d621d1853eac4182f97982cb5957247e

2013-05-29Residual coding to cache energy class of tokens.Sami Pietila
Proposal for tuning the residual coding by changing how the context from previous tokens is calculated. Storing the energy class of previous tokens instead of the token itself eases the critical path of HW implementations. Change-Id: I6d71d856b84518f6c88de771ddd818436f794bab

Adding API to read/write uncompressed frame header bits (it is not final yet). Separate functions to read/write uncompressed header. Moving clr_type, error_resilient_mode, refresh_frame_context, frame_parallel_decoding_mode, frame_context_idx from compressed partition to uncompressed frame header.

2013-05-27a few clean-upsYaowu Xu
1. remove prediction mode conversion 2. unified bmode, same for key and non-key frame 3. set I4X4_PRED count for pdf to 0, as I4X4_PRED is no longer coded ever. It is determined by ref_frame and block partition Change-Id: If5b282957c24339b241acdb9f2afef85658fe47d

2013-05-27Reduce bmi buffer length from 16 to 4Jingning Han
This commit removes the use of bmi_ in the first-pass encoding by forcing encode_intra4x4block_ to use DC_PRED, followed by DCT_DCT only, as John suggested. This makes the need for bmi buffer only up to 4 entries, instead of 16. Change-Id: I3410007dfae789ee46a09ae20c39d3ce3c7954aa

2013-05-23Change txfm_type decisionYaowu Xu
The changing in intra coding to base on transform block, i.e. pred-> txfm->quant->dequant-itxfm->recon, made all blocks within a prediction unit behave consistently, there is no longer a need to handle blocks differently based on the position within a predicitn block. So this commit simplifies the decision of transform type to be based on prediction mode only. Change-Id: If96cb72386f2e9186126ace88afa35ef085b6c96

2013-05-22changes intra coding to be based on txfm blockYaowu Xu
This commit changed the encoding and decoding of intra blocks to be based on transform block. In each prediction block, the intra coding iterates thorough each transform block based on raster scan order. This commit also fixed a bug in D135 prediction code. TODO next: The RD mode/txfm_size selection should take this into account when computing RD values. Change-Id: I6d1be2faa4c4948a52e830b6a9a84a6b2b6850f6

2013-05-21Make the intra rd search support 8x4/4x8Jingning Han
This commit allows the rate-distortion optimization of intra coding capable of supporting 8x4 and 4x8 partition settings. It enables the entropy coding of intra modes in key frame using a unified contextual probability model conditioned on its above/left prediction modes. Coding performance: derf 0.464% Change-Id: Ieed055084e11fcb64d5d5faeb0e706d30268ba18

The API is not final yet and can be changed. Actual layout of uncompressed frame part will be finalized later. Right now moving clr_type, error_resilient_mode, refresh_frame_context, frame_parallel_decoding_mode from first compressed partition to uncompressed frame part.

2013-05-21Refinements on modelcoef expt to reduce storageDeb Mukherjee
Uses more aggrerssive interpolation to reduce storage for the model tables by almost more than half. Only 48 lists of probs are stored (as opposed to 128 before), corresponding to ONE_NODE probabilities of: 1, 3, 7, 11, ..., 115, 119, 127, 135, ..., 247, 255. Besides, only 1 table is used as opposed to 2 before. So the overall memory needed for the tables is just 48 * 8 = 384 bytes. The table currently used is based on a new Pareto distribution with heavier tail than a generalized Gaussian - which improves results on derf by about 0.1% over a single table Generaized Gaussian. Results overall on derfraw300 is -0.14%. Change-Id: I19bd03559cbf5894a9f8594b8023dcc3e546f6bd
2013-05-20Updating the model coef experimentDeb Mukherjee
Cleans up the experiment. Actually uses reduced counts for backward updates, and reduced number of probabilities in the context. No change in bitstream when the experiment is on. Between expt on and off: derfraw300 is down only -0.062% (which is better than when expts were run previously). Change-Id: I55285a049a0c22810bdb42914212ab5a4f8521b5
2013-05-20WIP: 4x4 idct/recon mergeScott LaVarnway
This patch eliminates the intermediate diff buffer usage by combining the short idct and the add residual into one function. The encoder can use the same code as well. Change-Id: I296604bf73579c45105de0dd1adbcc91bcc53c22
2013-05-19Enable bit-stream support to 8x4 and 4x8 partitionJingning Han
The recursive partition type search is enabled down to 4x4, 4x8 and 8x4, followed by the corresponding rate-distortion optimization for the per-partition encoding mode decisions. The bit-stream writing/reading synchronized in supporting the rectangular partition of 8x8 block. This provides above 1% coding performance gains on derf. To do next: 1. re-design the rate-distortion loop for inter prediction below 8x8. 2. re-design the rate-distortion loop for intra prediction below 4x4. 3. make the loop-filter aware of rectangular partition of 8x8 block. 4. clean the unused probability models. 5. update default probability values.
