Change Log

(06/10/2016) [1.0.1]

Fixed bugs:

  • Fix feature while looping by moving feof to after read_image.
  • Fix issue #2 use hashed string for log filename and result filename to avoid file names getting too long.

New features:

  • Add SsimFeatureExtractor and MsSsimFeatureExtractor with intermediate features (luminence, contrast, structure).

(06/16/2016) [1.0.2]

New features:

  • Refactor feature code to expose ssim/ms-ssim, speed up ssim/ms-ssim.

(07/20/2016) [1.0.3]

New features:

  • Add base class NorefFeatureExtractor for any feature extractor that do not use a reference video.
  • Add MomentNorefFeatureExtractor subclassing NorefFeatureExtractor as an example implementation.

(07/21/2016) [1.0.4]

Fixed bugs:

  • Fix a series of numerical issues in VMAF features, increment VmafFeatureExtractor version number.
  • Retrain VmafQualityRunner after feature update, increment version number.

(08/20/2016) [1.0.5]

New features:

  • Add LocalExplainer class.
  • Add show_local_explanation option to run_vmaf script.

(08/20/2016) [1.0.6]

New features:

  • Add DisYUVRawVideoExtractor and related classes.
  • Add NeuralNetworkTrainTestModel base class that integrates TensorFlow.
  • Add example class ToddNoiseClassifierTrainTestModel.

(08/20/2016) [1.0.7]

New features:

  • Update VmafFeatureExtractor to 0.2.2b with scaled ADM features exposed (adm_scale0-3).

(09/07/2016) [1.0.8]

New features:

  • Generalize read_dataset to allow specifying width, height and resampling method on which to calculate quality.
  • Add bicubic to SUPPORTED_RESAMPLING_TYPES for Asset.
  • Update Asset rule with resampling_type in str to avoid duplicates in data store.

(09/09/2016) [1.0.9]

Fixed bugs:

  • Move VmafQualityRunnerWithLocalExplainer to quality_runner_adhoc to resolve multiple instances of VMAF found when calling QualityRunner.find_subclass.

New features:

  • Add custom_clip_0to1 to TrainTestModel.

(09/28/2016) [1.1.0]

New features:

  • Update wrapper/vmafossexec: 1) it now takes pkl model file as input, so that slopes/intercepts are no longer hard-coded; 2) it now takes multiple YUV input formats; 3) add flag to enable/disable VMAF score clipping at 0/100; 4) allow customly running PSNR/SSIM/MS-SSIM; 5) allow customly outputing XML/JSON
  • Add SSIM/MS-SSIM option in run_testing.

(09/29/2016) [1.1.1]

New features:

  • Update command lines run_vmaf, run_psnr, run_vmaf_in_batch, run_cleaning_cache, run_vmaf_training and run_testing.

(10/5/2016) [1.1.2]

Fixed bugs:

  • Make ptools work under Mac OS.
  • Update SklearnRandomForestTrainTestModel test with sklearn 0.18.

(10/6/2016) [1.1.3]

New features:

  • Generalize dataset format to allow per-content YUV format.

(10/7/2016) [1.1.4]

Fixed bugs:

  • Issue #29: Make ptools build under Fedora.

(10/8/2016) [1.1.5]

(10/14/2016) [1.1.7]

Fixed bugs:

  • Issue #36: SSIM and MS-SSIM sometimes get negative values.
