Selective Search for Object Detection (C++ / Python)

In this tutorial, we will understand an important concept called “Selective Search” in Object Detection. We will also share OpenCV code in C++ and Python. Object Detection vs. Object Recognition An object recognition algorithm identifies which objects are present in an image. It takes the entire image as an input and outputs class labels and… Read More »

Color spaces in OpenCV (C++ / Python)

In this tutorial, we will learn about popular colorspaces used in Computer Vision and use it for color based segmentation. We will also share demo code in C++ and Python. In 1975, the Hungarian Patent HU170062 introduced a puzzle with just one right solution out of 43,252,003,274,489,856,000 (43 quintillion) possibilities. This invention now known as… Read More »
