Changelog

0.14: January 25, 2021

Changed:

  • Default value of ConfigurationOptions::smallestFaceHeight has been increased from 20px to 40px.

  • Downloadable model file formats have changed. You will need to re-run the model download scripts if upgrading from an older SDK version.

  • Changed sample app images.

Fixed:

  • Fixed bug which impacted Faceprint feature vector integrity with calls to jsonToFaceprint and faceprintToJson when ConfigurationOptions::frVectorCompression was set to true. The format of serialized Faceprint feature vectors (generated with frVectorCompression = true) has changed and therefore old serialized Faceprints which were generated and saved cannot be used with new versions of the SDK.

  • MXNET_CUDNN_AUTOTUNE_DEFAULT environment variable is now properly read by the GPU SDK. MXNET_CUDNN_AUTOTUNE_DEFAULT=0 should be set when variable-sized input images are used.

0.13: January 15, 2021

Removed:

  • Removed functions which were marked as deprecated in release 0.11.

Fixed:

  • Fixed bug in python bindings function identify_top_candidates.

0.12: January 4, 2021

Added:

  • Added Windows SDK to downloads page.

Fixed:

  • Cap similarityMeasure at 1.f, previously could sometimes exceed 1 due to rounding errors.

  • Improved 1 to N identification sample apps, better demonstrate how to select high quality enrollment images. Improved 1 to N identification documentation.

  • Fixed getFaceFeatureVectors function when running GPU SDK with enableGPU set to false.

0.11: December 23, 2020

Changed:

  • Function prototype changed for removeByIdentity. Now returns the number of Faceprints which were deleted from the collection.

  • enrollTemplate has been deprecated, use enrollFaceprint instead.

  • getLargestFaceFeatureVector(Faceprint&) has been deprecated, use getLargestFaceFeatureVector(Faceprint&, bool&) instead.

Fixed:

  • Fixed bug with logger.

0.10: December 11, 2020

New features and enhancements:

  • Face recognition template generation speed improvements on x86 CPU (both LITE and FULL model template generation nearly twice as fast). The RAM usage has also increased, the FULL model now using 2Gb RAM (previously 1.1Gb), and the LITE model using 55Mb RAM (previously 35Mb).

Changed:

  • SDK now supports CPUs which have AVX instruction set and don’t have AVX2 instruction set (previously our SDK required AVX2 CPUs). SDK uses runtime dispatching and will run significantly faster on CPUs supporting AVX2.

  • faceprintToJson no longer adds newline to json elements.

0.9: November 20, 2020

New features and enhancements:

  • Python3.7 bindings for AArch64 and Arm32 SDK (previously only python3.6).

  • Added setImage overload which accepts buffer to encoded JPG, PNG, or TIFF image

Changed:

  • Changed scripts for downloading runtime model files. They are now located in the download_models directory.

Fixed:

  • Fixed bug with GPU face detector where smallestFaceHeight parameter was not being used.

  • Bug in spoof code which was producing incorrect results. Spoof function prototype has also been changed, must provided the FaceBoxAndLandmarks of the face to be analyzed.

Changed:

  • Function prototype changed for isLicensed function. Now returns how many days are remaining for the license token.

0.8: November 9, 2020

New features and enhancements:

  • All Python classes have a __repr__ method.

  • Python bindings for AArch64 and Arm32 SDK.

  • Log number of days remaining for license.

  • Can use images residing in CUDA memory for face detection and recognition.

  • Added PostgreSQL DatabaseManagementSystem support.

  • Added faceprintToJson and jsonToFaceprint functions for deserializing / serializing Faceprint objects as strings.

  • Improved sample apps.

  • Environment variable for setting log level.

  • Improved documentation.

Changed:

  • Version number can be obtained from python bindings using tfsdk.SDK.get_version()

0.7: August 14, 2020

New features and enhancements:

  • Added detectGlasses API for detecting eye glasses

  • Added detectMask API function for detecting face masks

  • Added glasses detection sample codes (C++ and python).

  • Added mask detection sample apps (C++ and python).

  • Spoof model improvements.

  • Reduce SDK size.

  • No longer need to register all the GPUs in a machine in order to use one GPU with the SDK.

Changed:

  • Changed TRUEFACE_LICENSE to TRUEFACE_TOKEN in python bindings sample apps.

  • Spoof score has been inverted, 1 indicates real, 0 indicates fake.

  • detectMask now takes 1 additional parameter, maskScore.

0.6: July 7, 2020

New features and enhancements:

  • Face mask detection (currently on the CUDA engine only).

  • Setting smallestFaceHeight to -1 adjusts the face detection scale range from image-height/32 to image-height.

  • Read license token from environment variable in python sample apps.

Method signature changes:

  • Renamed createCollection to createLoadCollection.
