Tensorflow Face Detector

A mobilenet SSD(single shot multibox detector) based face detector with pretrained model provided, powered by tensorflow object detection api, trained by WIDERFACE dataset.

Features

Speed, run 60fps on a nvidia GTX1080 GPU.

Memory, requires less than 364Mb GPU memory for single inference.

Robust, adapt to different poses, this feature is credit to WIDERFACE dataset, I manually cleaned the dataset to balance the precision and recall trade off.

Parallel, multiple process video processing, can inference multiple input simultaneously, I tested to process 4 videos on a single GPU card at the same time, the speed is still competitive, and there's still room to accommodate more processes.

Dependencies

Tensorflow > 1.2

Tensorflow object detection api (Please follow the official installation instruction, otherwise, I cannot guarantee that you can run the code)

OpenCV python

Usage

Effect

Click Youtube to view the effect or Youku.

Prepare pre-trained model

Click here to download the pre-trained model from google drive. Put the model under the model folder.

Prepare video

Put your test video (mp4 format) under the media folder, rename it as test.mp4.

Run video detection

At the source root

python inference_video_face.py

After finished the processing, find the output video at media folder.

Run detection from usb camera

You can see how this face detection works with your web camera.

usage:inference_usbCam_face.py (cameraID | filename)

Here is an example to use usb camera with cameraID=0.

python inference_usbCam_face.py 0

Note: this script does not save video.

Known Issue

Please view that issue here if your output video is blank. A brief reminder is: check the input codec and check the input/output resolution, since this part is irrelevant to the algorithm, no modification will be made to master branch.
