In this tutorial, you will learn how to take any pre-trained deep learning image classifier and turn it into an object detector using Keras, TensorFlow, and OpenCV. Today, we’re starting a four-part series on deep learning and object detection: Part…

In this tutorial, you will learn how to use OpenCV and the Fast Fourier Transform (FFT) to perform blur detection in images and real-time video streams. Today’s tutorial is an extension of my previous blog post on Blur Detection with…

In this tutorial, you will learn how to implement a COVID-19 social distancing detector using OpenCV, Deep Learning, and Computer Vision. Today’s tutorial is inspired by PyImageSearch reader Min-Jun, who emailed in asking: Hi Adrian, I’ve seen a number of…

In this tutorial, you will learn how to utilize Tesseract to detect, localize, and OCR text, all within a single, efficient function call. Back in September, I showed you how to use OpenCV to detect and OCR text. This method…

In this tutorial, you will learn how to perform image inpainting with OpenCV and Python. Image inpainting is a form of image conservation and image restoration, dating back to the 1700s when Pietro Edwards, director of the Restoration of the…

In this tutorial, we will learn how to apply Computer Vision, Deep Learning, and OpenCV to identify potential child soldiers through automatic age detection and military fatigue recognition. Military service is something of personal importance to me, something I consider…

In this tutorial, you will learn how to train a COVID-19 face mask detector with OpenCV, Keras/TensorFlow, and Deep Learning. Last month, I authored a blog post on detecting COVID-19 in X-ray images using deep learning. Readers really enjoyed learning…

In this tutorial, you will learn how to fine-tune ResNet using Keras, TensorFlow, and Deep Learning. A couple of months ago, I posted on Twitter asking my followers for help creating a dataset of camouflage vs. noncamouflage clothes: This dataset…

In this tutorial, you will learn how to detect and remove duplicate images from a dataset for deep learning. Over the past few weeks, I’ve been working on a project with Victor Gevers, the esteemed ethical hacker from the GDI.Foundation,…
