Changelog

Note

The changelog is written with respect to the C++ SDK and therefore references C++ functions and data types. However, the same changes apply to the python bindings SDK and the corresponding functions and data types - the two SDKs are kept in sync.

v0.17: March 11, 2021

Changed:

  • Trueface::SDK::detectGlasses() now returns glasses confidence score.

  • Improved python bindings documentation to provide more information regarding function parameters and return values.

Fixed:

  • Fixed bug with Trueface::SDK::getFaceFeatureVectors() when using CPU inference with GPU SDK.

Deprecated:

  • Marked Trueface::SDK::detectSpoof(), Trueface::SDK::detectBlink(), and Trueface::SDK::getFaceLandmarks() as deprecated due to suboptimal performance.

v0.16: February 25, 2021

Added:

  • New face recognition model Trueface::FacialRecognitionModel::TFV5. We have deprecated the Trueface::FacialRecognitionModel::FULL model (TFv4) but will continue to support it for clients with existing collections. More details on the FAQ page

  • Added download_face_recognition_tfv5_cpu.sh and download_face_recognition_tfv5_gpu.sh which must be run in order to use TFv5 (use the respective script for your target platform).

Changed:

  • Trueface::FacialRecognitionModel::FULL face recognition model download scripts have been changed from download_face_recognition_cpu.sh and download_face_recognition_gpu.sh to download_face_recognition_tfv4_cpu.sh and download_face_recognition_tfv4_gpu.sh.

  • Trueface::FacialRecognitionModel::FULL face recognition model (TFv4) is not longer embedded in the SDK and must be downloaded by running download_face_recognition_tfv4_cpu.sh. This has reduced the SDK binary size by about 230Mb.

Removed:

  • Removed ARM C++ lite downloads from main downloads page. These builds are now redundant as the FULL model is no longer embedded in the SDK.

v0.15: February 16, 2021

Changed:

  • Can choose to run inference on GPU for individual modules using Trueface::EnableGPU configuration option.

  • Changed identification.cpp, identification.py, and identification_live_streaming.py sample code to demonstrate usage of new collection metadata functions.

Added:

  • Trueface::SDK::createCollection(), Trueface::SDK::loadCollection(), and Trueface::SDK::deleteCollection() API functions. Calling Trueface::SDK::createCollection() then subsequently Trueface::SDK::loadCollection() is equivalent to calling Trueface::SDK::createLoadCollection().

  • Trueface::SDK::getCollectionNames() API function returns a list of the names of all the collections in the database.

  • Trueface::SDK::getCollectionMetadata() API function returns the metadata for the specified collection in the database, loaded or unloaded.

  • Trueface::SDK::getCollectionIdentities() API function returns a map of identities and UUIDs for the specified collection in the database, loaded or unloaded.

  • Trueface::CollectionMetadata API struct, returned by Trueface::SDK::getCollectionMetadata().

v0.14: January 25, 2021

Changed:

  • Default value of Trueface::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 Trueface::SDK::jsonToFaceprint() and Trueface::SDK::faceprintToJson() when Trueface::ConfigurationOptions.frVectorCompression was set to true. The format of serialized Faceprint feature vectors (generated with Trueface::ConfigurationOptions.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.

v0.13: January 15, 2021

Removed:

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

Fixed:

  • Fixed bug in python bindings function Trueface::SDK::identify_top_candidates().

v0.12: 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 Trueface::SDK::getFaceFeatureVectors() function when running GPU SDK with Trueface::enableGPU set to false.

v0.11: December 23, 2020

Changed:

  • Function prototype changed for Trueface::SDK::removeByIdentity(). Now returns the number of Faceprints which were deleted from the collection.

  • Trueface::SDK::enrollTemplate() has been deprecated, use Trueface::SDK::enrollFaceprint() instead.

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

Fixed:

  • Fixed bug with logger.

v0.10: December 11, 2020

New features and enhancements:

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

  • Trueface::SDK::faceprintToJson() no longer adds newline to json elements.

v0.9: November 20, 2020

New features and enhancements:

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

  • Added Trueface::SDK::setImage(const std::vector<uint8_t>&) 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.

  • Function prototype changed for Trueface::SDK::isLicensed() function. Now returns how many days are remaining for the license token.

Fixed:

  • Fixed bug with GPU face detector where Trueface::ConfigurationOptions.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 Trueface::FaceBoxAndLandmarks of the face to be analyzed.

v0.8: 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 Trueface::SDK::faceprintToJson() and Trueface::SDK::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()

v0.7: August 14, 2020

New features and enhancements:

  • Added Trueface::SDK::detectGlasses() API for detecting eye glasses

  • Added Trueface::SDK::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.

  • Trueface::SDK::detectMask() now takes 1 additional parameter, maskScore.

v0.6: July 7, 2020

New features and enhancements:

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

  • Setting Trueface::ConfigurationOptions.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 Trueface::SDK::createCollection() to Trueface::SDK::createLoadCollection().
