BinaryCoP

Binary Neural Network-based COVID-19 Face-Mask Wear and Positioning Predictor on Edge Devices

XOHW Team Number: xohw21-142

High Performance (Multi-Gate/Camera)	Low Power (Single Gate/Camera)

Our Goal

Deploy accurate, unbiased image classification algorithms, which can be used at entrances or speed-gates to check correct mask wear and positioning, with all processing on low-power, cheap, edge hardware to preserve privacy of passing users. Alt text

Example Notebook and Documentation

Example Jupyter notebook to test a prototype of BinaryCoP on a standard PYNQ-board.
Docs contains extended report and slides.
Other Utils:
- Script to generate Grad-CAM interpretability results from trained networks.
- DSP-BitPacking script to rewire XNOR operations through DSP blocks.

Requirements and Dependencies

PYNQ-Z1 with PYNQ 2.5 image.
DSP-BitPacking synthesis tested on Vivado 2018.1 with BNN-PYNQ.
