Comprehensive guide to installing OpenCV 4.1.0 on Ubuntu 18.04 from source
OpenCV is an open source computer vision library which is very popular for performing basic image processing tasks such as blurring, image blending, enhancing image as well as video quality, thresholding etc. In addition to image processing, it provides various pre-trained deep learning models which can be directly used to solve simple tasks at hand. […]

Deep Learning based image colorization with OpenCV
In India, we celebrated the festival of color “Holi” last week. We celebrate the end of the winter with a splash of color because that’s what the spring will bring us in a few days. When I was young, the celebrations were sparse. It was the decade of frugal parenting. We waited for festivals so […]

Deep Learning based Edge Detection in OpenCV
In this post, we will learn how to use deep learning based edge detection in OpenCV which is more accurate than the widely popular canny edge detector. Edge detection is useful in many use-cases such as visual saliency detection, object detection, tracking and motion analysis, structure from motion, 3D reconstruction, autonomous driving, image to text […]

Case-Study: Better HAAR feature-based Eye Detector using OpenCV
Motivation behind this post: Opencv object detectors which are built using Haar feature-based cascade classifiers is at least a decade old. OpenCV framework provides a default pre-built haar and lbp based cascade classifiers for face and eye detection which are very good quality detectors. However, I had never measured the accuracy of these face and […]
