Snapshot from the Face Video Segmentation Editor.

This project contains a collection of tools for semi-supervised gathering of ground truth face segmentation data from videos. A stable hierarchy of regions with temporal coherence is computed from dense optical flow using the method of [2]. Facial landmarks, extended to also include the forehead, are then used to extract the face contour. Regions are classified as belonging to the face segment according to their overlap with the face contour. The regions can then be further processed using a simple interface which allows browsing the entire video and manually classifying the regions using simple mouse clicks.

| Library | Minimum Version | Notes |
|---|---|---|
| Boost | 1.47 | |
| OpenCV | 3.0 | |
| find_face_landmarks | 1.1 | |
| video_segment | 1.0 | |
| protobuf | 3.0.0 | |
| Qt | 5.4.0 |
- Use CMake and your favorite compiler to build and install the library.
- Add face_video_segment/bin to path.
- Add face_video_segment/interfaces/matlab to Matlab's path.
- Download the landmarks model file.
For using the library's C++ interface, please take a look at the Doxygen generated documentation.
Before running the pipeline please prepare an input directory with all the face videos for processing, and an output directory that will contain all the experiment data. To execute the entire automatic pipeline use the following Matlab code:
inDir = 'videos'; % Input videos directory
outDir = 'fvs_expr'; % Output directory
landmarksFile = 'shape_predictor_68_face_landmarks.dat'; % Landmarks model file
face_video_seg_batch(inDir, outDir, landmarksFile);Now we have 4 directories in "fvs_expr":
- seg_trees - Containing the all the video segmentations hierarchies for each video.
- landmarks - Containing all the landmarks for each video.
- fvs_files - Containing all the classified regions for each video.
- output - Containing all the keyframe images and segmentations for each video in a separate directory.
For additional manual processing go to the "fvs_files" directory and edit the appropiate file with the fvs_editor.
fvs_editor video_name.fvs
On Windows you can right click the .fvs file, select open with... and point to the fvs_editor.
To regenerate the output images and segmentations you can either use fvs_write_keyframes.m:
fvsFile = 'fvs_expr/fvs_files/video_name.fvs'; % Edited fvs file
outDir = 'fvs_expr/output/video_name'; % Output directory for the specific video
face_video_seg_batch(fvsFile, outDir);Or you can delete the corresponding video directories in "fvs_expr/output" and re-run the automatic pipeline (existing files will not be overwritten).
To convert the generated ground truth to a dataset in PASCAL VOC format, do the following: Create an empty trainval.csv file:
fvs_init_trainval('fvs_expr/output', 'fvs_expr/output/trainval.csv');Fill the "target" column in the trainval.csv file with "train" for training, "val" for valuation, or leave empty for ignoring the video. Then to produce the dataset:
produce_pascal_voc_db('fvs_expr/output', 'fvs_expr/pascal_voc_db');Use "add_pascal_voc_db.m" to add additional images and segmentations to the dataset.
