How to install dlib

Two weeks ago I interviewed Davis King, the creator and chief maintainer of the dlib library. Today I am going to demonstrate how to install dlib with Python bindings on both macOS and Ubuntu. I highly encourage you to take the time to install dlib on your system over the next couple of days. Starting next week we’ll […]

ImageNet: VGGNet, ResNet, Inception, and Xception with Keras

A few months ago I wrote a tutorial on how to classify images using Convolutional Neural Networks (specifically, VGG16) pre-trained on the ImageNet dataset with Python and the Keras deep learning library. The pre-trained networks inside of Keras are capable of recognizing 1,000 different object categories, similar to objects we encounter in our day-to-day lives with high […]

Text skew correction with OpenCV and Python

Today’s tutorial is a Python implementation of my favorite blog post by Félix Abecassis on the process of text skew correction (i.e., “deskewing text”) using OpenCV and image processing functions. Given an image containing a rotated block of text at an unknown angle, we need to correct the text skew by: Detecting the block of text in the […]

A day in the life of a Adrian Rosebrock: computer vision researcher, developer, and entrepreneur.

Ever wonder what it’s like to work as a computer vision researcher or developer? You’re not alone. Over the past few years running PyImageSearch I have received emails and inquiries that are “outside” traditional computer vision and OpenCV questions. They instead focus on something much more personal — my daily life. PyImageSearch reader Jared, asked: “What is […]

Seam carving with OpenCV, Python, and scikit-image

Easily one of my all-time favorite papers in computer vision literature is Seam Carving for Content-Aware Image Resizing by Avidan and Shamir from Mitsubishi Electric Research Labs (MERL). Originally published in the SIGGRAPH 2007 proceedings, I read this paper for the first time during my computational photography class as an undergraduate student. This paper, along with […]
