YOLOv3 - Deep Learning Based Object Detection
In this post, we will understand what is Yolov3 and learn how to use YOLOv3 — a state-of-the-art object detector — with OpenCV. YOLOv3 is the latest variant of a popular object detection algorithm YOLO – You Only Look Once. The published model recognizes 80 different objects in images and videos, but most importantly, it is super fast and nearly as accurate as Single Shot MultiBox (SSD). Starting

OpenCV on Mac OS X
OpenCV on Mac OS X Some time ago, I managed to compile Intel’s Open Computer Vision library on Mac OS X. In this article, I hope to explain how I got it to work. I’ll list the prerequisites, then explain how to compile and install OpenCV as well as a sample program to get you started. I’ll describe quirks in using OpenCV on the Mac as I stumble upon them. The description of the installation proces
