TFace

TFace: A trusty face recognition research platform developed by Tencent Youtu Lab. It provides a high-performance distributed training framework and releases our efficient methods implementation.

This framework consists of several modules: 1. various data augmentation methods, 2. backbone model zoo, 3. our proposed methods for face recognition and face quality, 4. test protocols of evalution results and model latency.

Getting Started

Train Data

The training dataset is organized in tfrecord format for efficiency. The raw data of all face images are saved in tfrecord files, and each dataset has a corresponding index file(each line includes tfrecord_name, trecord_index offset, label).

The IndexTFRDataset class will parse the index file to gather image data and label for training. This form of dataset is convenient for reorganization in data cleaning(do not reproduce tfrecord, just reproduce the index file).

1. Convert raw image to tfrecords, generate a new data dir including some tfrecord files and a index_map file

   python3 tools/img2tfrecord.py --img_list=${img_list} --pts_list=${pts_list} --tfrecords_name=${tfr_data_name}

2. Convert old index file(each line includes image path, label) to new index file

   python3 tools/convert_new_index.py --old=${old_index} --tfr_index=${tfr_index} --new=${new_index}

3. Decode the tfrecords to raw image

   python3 tools/decode.py --tfrecords_dir=${tfr_dir} --output_dir=${output_dir}

Augmentation

Data Augmentation module implements some 2D-based methods to generated some hard samples, e.g., maks, glass, headscarf. Details see Augmentation

Train

Modified the DATA_ROOTandINDEX_ROOTin ./tasks/distfc/train_confing.yaml, DATA_ROOT is the parent dir for tfrecord dir, INDEX_ROOT is the parent dir for index file.

bash local_train.sh
