Low-Resource-QR-Code-Reader

Overview

Topic : QR Code Reader Optimization for Low Resource Embedded System

Purpose : The purpose of the project is to develop a QR code reader with low memory usage and short execution time for a AR glass based on a low resource embedded system. The AR glass make people examine the decode result of a QR code.

Program Version Comparison

The program is run on Raspberry 4 2GB, and the memory usage is estimated by Valgrind
