I’m writing a book on Computer Vision and the Raspberry Pi (and I need your input).

Today is a big day — I’m formally announcing that I’m writing a brand new book on Computer Vision with the Raspberry Pi. I’ve been wanting to write this book for years, arguably ever since I started playing around with the Raspberry Pi and OpenCV. But the timing never worked out quite right. I was […]

Liveness Detection with OpenCV

In this tutorial, you will learn how to perform liveness detection with OpenCV. You will create a liveness detector capable of spotting fake faces and performing anti-face spoofing in face recognition systems. Over the past year, I have authored a number of face recognition tutorials, including: OpenCV Face Recognition Face recognition with dlib, Python, and […]

Holistically-Nested Edge Detection with OpenCV and Deep Learning

In this tutorial, you will learn how to apply Holistically-Nested Edge Detection (HED) with OpenCV and Deep Learning. We’ll apply Holistically-Nested Edge Detection to both images and video streams, followed by comparing the results to OpenCV’s standard Canny edge detector. Edge detection enables us to find the boundaries of objects in images and was one of the […]

Black and white image colorization with OpenCV and Deep Learning

In this tutorial, you will learn how to colorize black and white images using OpenCV, Deep Learning, and Python. Image colorization is the process of taking an input grayscale (black and white) image and then producing an output colorized image that represents the semantic colors and tones of the input (for example, an ocean on […]

Breast cancer classification with Keras and Deep Learning

In this tutorial, you will learn how to train a Keras deep learning model to predict breast cancer in breast histology images. Back 2012-2013 I was working for the National Institutes of Health (NIH) and the National Cancer Institute (NCI) to develop a suite of image processing and machine learning algorithms to automatically analyze breast […]
