# Object-Detector-App

A real-time object recognition application using [Google's TensorFlow Object Detection API](https://github.com/tensorflow/models/tree/master/research/object_detection) and [OpenCV](http://opencv.org/).

## Getting Started

1. `conda env create -f environment.yml`

2. `python object_detection_app.py` / `python object_detection_multithreading.py`

    Optional arguments (default value):

    * Device index of the camera `--source=0`

    * Width of the frames in the video stream `--width=480`

    * Height of the frames in the video stream `--height=360`

    * Number of workers `--num-workers=2`

    * Size of the queue `--queue-size=5`

    * Get video from HLS stream rather than webcam '--stream-input=http://somertmpserver.com/hls/live.m3u8'

    * Send stream to livestreaming server '--stream-output=--stream=http://somertmpserver.com/hls/live.m3u8'

## Tests

```

pytest -vs utils/

```

## Requirements

- [Anaconda / Python 3.5](https://www.continuum.io/downloads)

- [TensorFlow 1.2](https://www.tensorflow.org/)

- [OpenCV 3.0](http://opencv.org/)

## Notes

- OpenCV 3.1 might crash on OSX after a while, so that's why I had to switch to version 3.0. See open issue and solution [here](https://github.com/opencv/opencv/issues/5874).

- Moving the `.read()` part of the video stream in a multiple child processes did not work. However, it was possible to move it to a separate thread.
