The journal of Open Source Software (currently being reviewed)},\n year = {submission in progress}\n}\n```\n\nHave a look to sibling project [inaSpeechSegmenter](https://github.com/ina-foss/inaSpeechSegmenter).\n\n\n## Installation\n`inaFaceAnalyzer` requires Python version between 3.7 and 3.9.\nPython 3.10 is not yet supported due to `onnxruntime-gpu` dependency.\n\n### Installing from sources\n```\napt-get install cmake ffmpeg libgl1-mesa-glx\ngit clone https://github.com/ina-foss/inaFaceAnalyzer.git\ncd inaFaceAnalyzer\npip install .\n./test_inaFaceAnalyzer.py # to check that the installation is ok\n```\n### Installing from pypi on ubuntu\n```\n# for GPU support, cuda, cudnn and nvidia drivers should be already installed\napt-get install cmake ffmpeg libgl1-mesa-glx\npip install inaFaceAnalyzer\n```\n\n### Using docker image\n```\n# download latest docker image from dockerhub\ndocker pull inafoss/inafaceanalyzer\n# run docker image. setting --gpu argument allows to take advantage of\n# GPU acceleration (non mandatory)\ndocker run -it --gpus=all inafoss/inafaceanalyzer /bin/bash\n# lauch unit tests (non mandatory but recommended)\npython test_inaFaceAnalyzer.py\n# use any program or API\nina_face_analyzer.py -h\n```\n\n\n## Using inaFaceAnalyzer command line programs\nSeveral scripts are provided with the distribution:\n* ina_face_analyzer.py : can perform the most common processings provided by the framework\n* ina_face_analyzer_webcam_demo.py : a demo script using webcam\n* ina_face_analyzer_distributed_server.py and ina_face_analyzer_distributed_worker : a set of scripts allowing to perform distributed analyses on a heterogeneous cluster.\n\nA detailed listing of all the options from the command line programs is available using the -h argument. We guess you don't want to read the whole listing at this point, but you can have a look at it later 😉.\n\n### Displaying detailed manual\n\n```bash\nina_face_analyzer.py -h\n```\n### Process all frames from a list of video (without tracking)\nVideo processing uses the video engine and requires a list of input video paths, together with a directory used to store results in CSV.\nProgram initialization time requires several seconds, and we recommend using large list of files instead of calling the program for each file to process.\n```bash\n# directory storing result must exist\nmkdir my_output_directory\n# -i is followed by the list of video to analyze, and -o is followed by the name of the output_directory\nina_face_analyzer.py --engine video -i ./media/pexels-artem-podrez-5725953.mp4 -o ./my_output_directory\n# displaying the first 2 lines of the resulting CSV\nhead -n 2 ./my_output_directory/pexels-artem-podrez-5725953.csv \n>> frame,bbox,detect_conf,sex_decfunc,age_decfunc,sex_label,age_label\n>> 0,\"(945, -17, 1139, 177)\",0.999998927116394,8.408014,3.9126961,m,34.12696123123169\n# using remote urls is also an option\nina_face_analyzer.py --engine video -i 'https://github.com/ina-foss/inaFaceAnalyzer/raw/master/media/pexels-artem-podrez-5725953.mp4' -o ./my_output_directory\n```\n\nThe resulting CSV contains several columns:\n* frame: frame position in the video (here we have 5 lines corresponding to frame 0 - so 5 detected faces)\n* bbox: face bounding box\n* detect_conf: face detection confidence (dependent on the detection system used)\n* sex_decfunc and age_decfunc: raw classifier output. Can be used to smooth results or ignored.\n* sex_label: m for male and f for female\n* age_label: age prediction\n\n\n### Faster processing of a video\nIf computation time is an issue, we recommend using --fps 1 which will process a single frame per second, instead of the whole amount of video frames. When using GPU architectures, we also recommend setting large batch_size values.\n```bash\n# here we process a single frame per second, which is 25/30 faster than processing the whole video\nina_face_analyzer.py --engine video --fps 1 --batch_size 128 -i ./media/pexels-artem-podrez-5725953.mp4 -o ./my_output_directory\n```\n### Using Tracking\nTracking allows to lower computation time, since it is less costly than a face detection procedure.\nIt also allows to smooth prediction results associated to a tracked face and obtain more robust estimates.\nIt is activated with the videotracking engine and requires to define detect_period, the time period (in frames) at which the face detector will be applied.\n```bash\n# Process 5 frames per second, use face detection for 1/3 and face tracking for 2/3 frames\nina_face_analyzer.py --engine videotracking --fps 5 --detect_period 3 -i ./media/pexels-artem-podrez-5725953.mp4 -o ./my_output_directory\n# displaying the first 2 lines of the resulting CSV\nhead -n 2 ./my_output_directory/pexels-artem-podrez-5725953.csv\n>> frame,bbox,face_id,detect_conf,track_conf,sex_decfunc,age_decfunc,sex_label,age_label,sex_decfunc_avg,age_decfunc_avg,sex_label_avg,age_label_avg\n>> 0,\"(945, -17, 1139, 177)\",0,0.999998927116394,,8.408026,3.9126964,m,34.12696361541748,8.391026,3.8831162,m,33.831162452697754\n```\nResulting CSV will contain additional columns with _avg suffixes, corresponding to the smoothed estimates obtained for each tracked face. It will also contain a face_id with a numeric identifier associated to each tracked face.\n\n### Exporting results\nResults visualization allows to validate if a given processing pipeline is suited to a specific material.\n--mp4_export generate a new video with embedded bounding boxes and classification information.\n--ass_subtitle_export generate a ASS subtitle file allowing to display bounding boxes and classification results in vlc or ELAN, and which is more convenient to share..\n\n```bash\n# Process 10 frames per second, use face detection for 1/2 and face tracking for 1/2 frames\n# results are exported to a newly generated MP4 video and ASS subtitle\nina_face_analyzer.py --engine videotracking --fps 10 --detect_period 2 --mp4_export --ass_subtitle_export -i ./media/pexels-artem-podrez-5725953.mp4 -o ./my_output_directory\n# display the resulting video\nvlc ./my_output_directory/pexels-artem-podrez-5725953.mp4\n# display the original video with the resulting subtitle files\nvlc media/pexels-artem-podrez-5725953.mp4 --sub-file my_output_directory/pexels-artem-podrez-5725953.ass \n```\n\n### Processing list of images\nThe processing of a list of images requires to use the image engine.\nA single resulting CSV will be generated with entries for each detected faces, together with a reference to their original filename.\n```bash\n# process all images stored in directory media, outputs a single csv file\nina_face_analyzer.py --engine image -i media/* -o ./myresults.csv\n# display first 2 lines of the result file\nhead -n 2 myresults.csv\n>> frame,bbox,detect_conf,sex_decfunc,age_decfunc,sex_label,age_label\n>> media/1546923312_7cc94957e8_o.jpg,\"(57, 104, 435, 483)\",1.0,14.436495,3.5770981,m,30.770981311798096\n```\n\n### Distributing analyses over a network\n\nWe provide two scripts allowing to perform distributed large-scale analyses.\n\nina_face_analyzer_distributed_server.py is in charge of distributing a list of documents to analyze to workers distributed over the network, and to define analysis options (fps, tracking, etc..).\nThe server requires 2 positional arguments: its host name (or IP) and the path to a CSV containing one line per file to process together with the destination path of the results.\nWorkers need to have writing permissions in the destination paths (mounted with NFS, sshfs, ...). Output directories are created on the fly if they don't exist. Jobs order is randomized before being distributed to the workers. When a destination file already exists, the corresponding analysis is skipped.\n\n```bash\n# a sample job list csv with 2 records and 4 columns\n# source_path (mandatory input file path or url)\n# dest_csv (mandatory output csv)\n# dest_ass: to be used for exporting results to ass subtitles\n# dest_mp4: to be used for exporting incrusted MP4 video\ncat test.scv\n>> source_path,dest_csv,dest_ass,dest_mp4\n>> /home/ddoukhan/git_repos/inaFaceAnalyzer/media/pexels-artem-podrez-5725953.mp4,/tmp/csv/test1.csv,/tmp/ass/test1.ass,/tmp/mp4/test1.mp4\n>> https://github.com/ina-foss/inaFaceAnalyzer/raw/master/media/pexels-artem-podrez-5725953.mp4,/tmp/csv/test2.csv,,\n# the server define an analysis procedure at 1 FPS\n# after initialization, it display a network adress to be passed to the workers\nina_face_analyzer_distributed_server.py blahtop.ina.fr test.csv --engine video --fps 1\n>> parsing joblist test.csv\n>> Total number of files to process: 2\nProvide the following objet URI to remote ina_face_analyzer_distributed_workers: PYRO:obj_4c027f06be5b40e7bcf2f3f1e235b68c@blahtop.ina.fr:33825\n```\n\nina_face_analyzer_distributed_worker.py is in charge of computing analyses and writing results to a centralized storage directory.\nIt requires the network adress displayed by the server in order to communicate. A good practice is to launch one worker per available GPU and set CUDA_AVAILABLE_DEVICES. Several workers can process the list of the server in parallel.\n```bash\n# CUDA_AVAILABLE_DEVICES=2 is non mandatory and tells the worker\n# to use a single GPU with id 2.\n# the PYRO:obj_ adress is displayed when lauching the server and\n# should copy/pasted when launching the worker\nCUDA_AVAILABLE_DEVICES=2 ina_face_analyzer_distributed_worker.py PYRO:obj_4c027f06be5b40e7bcf2f3f1e235b68c@blahtop.ina.fr:33825\n>> received job https://github.com/ina-foss/inaFaceAnalyzer/raw/master/media/pexels-artem-podrez-5725953.mp4 /tmp/test2.csv nan nan\n>> received job /home/ddoukhan/git_repos/inaFaceAnalyzer/media/pexels-artem-podrez-5725953.mp4 /tmp/test1.csv /tmp/test1.ass /tmp/test1.mp4\n>>all jobs are done\n```\n\n## Using inaFaceAnalyzer API\n\n`inaFaceAnalyzer`'s API documentation is based on several tutorial notebooks stored in directory [`tutorial_API_notebooks`](https://github.com/ina-foss/inaFaceAnalyzer/tree/master/tutorial_API_notebooks):\n\nWe provide below a brief description of these notebooks, together with links allowing to run them remotely in Google's colab platform.\nWhen using colab platform, we recommend to [take advantage of GPU acceleration](https://www.tutorialspoint.com/google_colab/google_colab_using_free_gpu.htm).\n\n* [Video Analysis Quick-Start](https://colab.research.google.com/github/ina-foss/inaFaceAnalyzer/blob/master/tutorial_API_notebooks/quick_start.ipynb): inaFaceAnalyzer is used to process video with default analysis parameters and export results to CSV, rich ASS subtitles and incrusted MP4. We also introduce FPS runtime argument allowing to speed-up analyses.\n* [Image Analysis Quick-Start](https://colab.research.google.com/github/ina-foss/inaFaceAnalyzer/blob/master/tutorial_API_notebooks/quick_start-image.ipynb): inaFaceAnalyzer is used to process image files. Final and intermediate results are displayed and exported to CSV.\n* [Advanced tutorial](https://colab.research.google.com/github/ina-foss/inaFaceAnalyzer/blob/master/tutorial_API_notebooks/advanced_tutorial.ipynb): define a custom analysis pipeline by defining 3 core parametric elements: face detection, face classification and image or video processing engine.\n\n## CREDITS\nThis work has been partially funded by the French National Research Agency (project GEM : Gender Equality Monitor : ANR-19-CE38-0012) and by European Union's Horizon 2020 research and innovation programme (project [MeMAD](https://memad.eu) : H2020 grant agreement No 780069).\n\nWe acknowledge contributions from [Zohra Rezgui](https://github.com/ZohraRezgui) who trained first models and wrote the first piece of code that lead to inaFaceAnalyzer during her internship at INA.\n```bibtex\n@techreport{rezgui2019carthage,\n type = {Msc.
