Object Detection - SSD-MobileNet

• Learn about MobileNets and separable depthwise convolutions.
• The SSD (Single Shot Detection) architecture used for object detection
• Use pretrained TensorFlow object detection inference models to detect objects
• Use different architectures and weigh the tradeoffs.
• Apply an object detection pipeline to a video.

Open the notebook and work through it!

Requirements

Install environment with Anaconda:

conda env create -f environment.yml

Change TensorFlow pip installation from tensorflow-gpu to tensorflow if you don't have a GPU available.

The environment should be listed via conda info --envs:

# conda environments:
#
carnd-advdl-odlab        /usr/local/anaconda3/envs/carnd-advdl-odlab
root                  *  /usr/local/anaconda3

Resources

• TensorFlow object detection model zoo
• Driving video

Future Work

• Experiment with Fast-R-CNN / Faster-R-CNN and compare its performance with SSD on the same * Driving video
