(2021-01-13) [v2.1.1]

This is a minor release to address a few last minute items for the initial AOM CTC.

  • Fixes a SSIM/MS-SSIM precision bug where a lossless comparison did not always result in a perfect 1.0 score. (#796).
  • Adds feature extractor options to clip the dB scores for both PSNR/SSIM. --aom_ctc v1.0 has been updated to use these clipping options according to the AOM CTC. (#802).

(2020-12-30) [v2.1.0]

This is a minor release for the initial AOM CTC. Support has been added for templated feature names. While this is a general purpose software feature, templated feature names are immediately useful for simultaneous computation of VMAF and VMAF NEG since the two metrics rely on slightly different VIF/ADM variations. Global feature overrides via the --feature flag are no longer supported, instead individual models can have their features overloaded individually, the syntax for which is as follows:

--model version=vmaf_v0.6.1:vif.vif_enhn_gain_limit=1.0:adm.adm_enhn_gain_limit=1.0

New features:

  • Per-model feature overloading via new API vmaf_model_feature_overload().
  • Multiple unique configurations of the same feature extractor may be registered run at the same time.
  • --aom_ctc v1.0 preset, encompassing all metrics specified by the AOM CTC.

(2020-12-4) [v2.0.0]

This is a major release with an updated and overhauled libvmaf API. The vmafossexec command line tool has been deprecated and replaced with the more flexible and powerful vmaf tool. For an introduction to the libvmaf v2.0.0 API as well as an explanation of the new vmaf tool, please see the following README files: libvmaf, vmaf. Also part of this release is a new fixed-point and x86 SIMD-optimized (AVX2, AVX-512) implementation that achieves ~2x speed up compared to the previous floating-point version.

New features:

  • Add PSNR-HVS and CIEDE2000 metrics.
  • ci/actions: upload linux/macos artifacts (#738)
  • libvmaf/feature: deprecate daala_ssim (#735)
  • libvmaf: remove support for pkl models
  • libvmaf/psnr: rewrite using integer types, 2x speedup
  • vmaf: if no model is specified, enable v0.6.1 by default (#730)
  • libvmaf/x86: add AVX2/AVX-512 optimizations for adm, vif and motion
  • ci/actions: add xxd to build dependencies for Windows
  • libvmaf: add support for built-in models
  • libvmaf/integer_vif: use symmetrical mirroring on edges
  • Fix log2 by replacing log2f_approx with log2f
  • libvmaf_rc: provide a backwards compatible compute_vmaf(), link vmafossexec with libvmaf
  • libvmaf: add framework support for json models
  • libvmaf/libsvm: update libsvm to version 324
  • libvmaf/motion: add motion_force_zero to motion fex
  • return sha1 if Asset string is longer than 255
  • Add CID/iCID Matlab source code
  • build: unbreak x86 builds (Fixes: #374)
  • Add 12bit and 16bit support for python YUV reader; add tests.
  • Add PypsnrFeatureExtractor
  • Add processes to FeatureAssembler. (#662)

Fixed bugs:

  • fix motion flush for single frame input
  • Fixing the perf_metric for a single entry list input
