Python OpenCV Image Processing – Resize, Blend, Blur, Threshold, Convert

by

This tutorial is an introduction to the OpenCV library. Learn how to convert color channels, resize, blend, blur, and threshold images in Python. The OpenCV [1] library contains most of the functions we need for working with images. Handling images in programming requires a different intuition than handling text data. An image is made up … Read more

What are the Applications of Graphs in Computer Science?

This article is contributed by our friendly AI from InferKit that uses a deep neural network to generate text automatically. I (human) guided the AI by proposing different subheadings that may be of interest to the reader. Surprisingly, there are many unique perspectives in the article—and some totally wrong “facts”. So, enjoy this fascinating demonstration … Read more

How to Extract Text from Images in Python using OpenCV and EasyOCR

by

You can extract text from images with EasyOCR, a deep learning-based OCR tool in Python. EasyOCR performs very well on invoices, handwriting, car plates, and public signs. First released in 2007, PyTesseract [1] is the to-go library for extracting text from images. It uses classical computer vision methods to perform optical character recognition (OCR), then … Read more
