How do I use OpenCV with GPU on Colab?
Run OpenCV’s “dnn” on Google Colab using its NVIDIA GPU. OpenCV’s ‘Deep Neural Network’ (dnn) module is a convenient tool for computer vision, it is very easy to apply some techniques such as Yolo and OpenPose. However, the major drawback of OpenCV was the lack of GPU support, resulting in slow inference.
