MobileNet SSD model intended for use with Motion software

MobileNet SSD model for Motion software

MobileNet SSD model here is intended for use with Intel's Movidius Neural Compute Stick and Motion software.

Upstream Motion software currently does not support Movidius yet, but if you are looking to try out Motion with Movidius support, head to my movidius branch.

How to install and run my movidius branch motion software

1. Install Movidius NCSDKv2. Follow the installation manual. Note that the NCSDKv2 may screw up your existing libraries, so I recommend trying this on a sacrificial machine. Alternatively, you could try installing just the API by running sudo make api (I have not tested this one).
2. Git clone the movidius branch into any directory you like.
   • git clone -b movidius https://github.com/jasaw/motion.git
3. Go into the directory and run:
   • autoreconf -fiv
   • ./configure
   • make
   • sudo make install
4. Download the MobileNet SSD graph file.
5. Add MVNC related configuration items to thread-1.conf file.
   • mvnc_enable on : This will bypass the original motion detection algorithm and use MVNC instead.
   • mvnc_graph_path MobileNetSSD.graph : Path to MobileNetSSD graph. Other neural net models are not supported.
   • mvnc_classification person,cat,dog,car : A comma separated classes of objects to detect.
   • mvnc_threshold 75 : This is confidence threshold in percentage, which takes a range from 0 to 100 as integer. A detected person is only considered valid if the neural net confidence level is above this threshold. 75 seems like a good starting point.

Pre-trained MobileNet SSD files

I downloaded the pre-trained MobileNet SSD files from https://github.com/chuanqi305/MobileNet-SSD and compiled them into a graph file.

• Caffe model was from here: https://drive.google.com/open?id=0B3gersZ2cHIxRm5PMWRoTkdHdHc
• Prototxt file was from here: https://raw.githubusercontent.com/chuanqi305/MobileNet-SSD/923b3128f25262b5010cef67e4fb9e4b6728ae7b/voc/MobileNetSSD_deploy.prototxt

To generate the MobileNet SSD graph file, go to motion directory and run:

make MobileNetSSD.graph
