In this tutorial, we will discuss the various Face Detection methods in OpenCV, Dlib and Deep Learning, and compare the methods quantitatively. We will share code in C++ and Python for the following ...
Deep learning based Object Detection and Instance Segmentation using Mask RCNN in OpenCV (Python / C++)
A few weeks back we wrote a post on Object detection using YOLOv3. In this post we will discuss Mask RCNN in OpenCV. The output of an object detector is an array of bounding boxes around ...
Heatmap for Logo Detection using OpenCV (Python)
In this post, we will learn how to create a heatmap to analyze annotations in a video sequence. We first elaborate on why this would be useful, give a real world application, and follow up ...
Deep Learning based Object Detection using YOLOv3 with OpenCV ( Python / C++ )
In this post, we will 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. ...
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 ...
Automatic Red Eye Remover using OpenCV (C++ / Python)
In this tutorial, we will learn how to remove red eyes from a photo completely automatically. Just thinking about this problem of red-eye removal brings back memories from my childhood. I grew up ...
