You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
I publish a brand new Computer Vision, Deep Learning, and OpenCV tutorial every Monday at 10AM EST. Here you'll find my most recent tutorials and guides.
Today’s post is a followup to a previous (extremely popular) article on detecting barcodes in images using Python and OpenCV. In the previous post we explored how to detect and find barcodes in images. But today we are going to…
