In this tutorial you will learn how to train a custom deep learning model to perform object detection via bounding box regression with Keras and TensorFlow. A dataset with images annotated with bounding boxes and class labels is essential for…

In this tutorial, you will learn how to perform image segmentation with Mask R-CNN, GrabCut, and OpenCV. A couple months ago, you learned how to use the GrabCut algorithm to segment foreground objects from the background. GrabCut worked fairly well…

In this tutorial, you will build a basic Automatic License/Number Plate Recognition (ANPR) system using OpenCV and Python. An ANPR-specific dataset, preferably with plates from various countries and in different conditions, is essential for training robust license plate recognition systems,…

In this tutorial, you will learn how to use the EasyOCR package to easily perform Optical Character Recognition and text detection with Python. EasyOCR, as the name suggests, is a Python package that allows computer vision developers to effortlessly perform…

Back in 2017, I asked Saideep Talari, then a PyImageSearch Gurus course graduate, to come onto the blog and share his story on how he changed his career from a security analyst to a machine learning engineer and computer vision…

In this tutorial, you will learn how to OCR a document, form, or invoice using Tesseract, OpenCV, and Python. Last week, we discussed how to accept an input image and align it to a template image, such as the following:…

In this post, I interview my former UMBC lab mate, Dr. Huguens Jean, who was just hired to work at Google’s Video AI Group as an artificial intelligence researcher. Huguens shares his inspirational story, starting from Port-au-Prince, Haiti where he…

In this tutorial, you will learn how to perform image alignment and image registration using OpenCV. Image alignment and registration have a number of practical, real-world use cases, including: Medical: MRI scans, SPECT scans, and other medical scans produce multiple…

In this tutorial, you will learn how to perform OCR handwriting recognition using OpenCV, Keras, and TensorFlow. This post is Part 2 in our two-part series on Optical Character Recognition with Keras and TensorFlow: Part 1: Training an OCR model…
