Bubble sheet multiple choice scanner and test grader using OMR, Python, and OpenCV - PyImageSearch
Getting Started Image Processing Tutorials by Adrian Rosebrock on October 3, 2016 Over the past few months I’ve gotten quite the number of requests landing in my inbox to build a bubble sheet/Scantron-like test reader using computer vision and image processing techniques. A dataset of filled-in bubble sheets is essential for this project. It allows for training a model to accurately recognize and
Self Driving RC Car
Objective Modify a RC car to handle three tasks: self-driving on the track, stop sign and traffic light detection, and front collision avoidance. System Design The system consists of three subsystems: input unit (camera, ultrasonic sensor), processing unit (computer) and RC car control unit. Input Unit A Raspberry Pi board (model B+), attached with a pi camera module and an HC-SR04 ultrasonic sens
Basic motion detection and tracking with Python and OpenCV - PyImageSearch
That son of a bitch. I knew he took my last beer. These are words a man should never, ever have to say. But I muttered them to myself in an exasperated sigh of disgust as I closed the door to my refrigerator. You see, I had just spent over 12 hours writing content for the upcoming PyImageSearch Gurus course. My brain was fried, practically leaking out my ears like half cooked scrambled eggs. And a
Find distance from camera to object using Python and OpenCV
A couple of days ago, Cameron, a PyImageSearch reader, emailed in and asked about methods to find the distance from a camera to an object/marker in an image. He had spent some time researching, but hadn’t found an implementation. I knew exactly how Cameron felt. Years ago I was working on a small project to analyze the movement of a baseball as it left the pitcher’s hand and headed for home plate.
Building image search an engine using Python and OpenCV - PyImageSearch
Examples of Image Search Engines Image Search Engine Basics Tutorials by Adrian Rosebrock on December 1, 2014 Let’s face it. Trying to search for images based on text and tags sucks. Whether you are tagging and categorizing your personal images, searching for stock photos for your company website, or simply trying to find the right image for your next epic blog post, trying to use text and keyword
Detecting Barcodes in Images with Python and OpenCV - PyImageSearch
Image Processing Tutorials by Adrian Rosebrock on November 24, 2014 UPDATE: The introduction to this post may seen a little “out there”. For some context, I had just finished watching the South Park Black Friday episodes prior to writing this post so I definitely had some inspiration regarding zombie shoppers, Black Friday chaos, and Game of Thrones. Black Friday is coming. Hordes of angry shopper
Super fast color transfer between images - PyImageSearch
Course information: 86+ total classes • 115+ hours hours of on-demand code walkthrough videos • Last updated: May 2025 ★★★★★ 4.84 (128 Ratings) • 16,000+ Students Enrolled I strongly believe that if you had the right teacher you could master computer vision and deep learning. Do you think learning computer vision and deep learning has to be time-consuming, overwhelming, and complicated? Or has to
Python/OpenCVで顔検出を利用した肌色検出 | ぱろすけのメモ帳
序論画像から肌色領域を検出する必要は、様々な場面で生じます。たとえば指や腕などをうまく切り分けることができればジェスチャーの認識が容易になります。肌色領域検出によって画像から人を検出するタスクも難易度が下がるでしょう。肌色領域検出は水玉コラを自動生成に役立つなど、愉快なアプリケーションも多くあります。というわけで本記事では画像から肌色領域の検出をする手法を提案し、その実装を示し、実験により性能を検証します。修士論文書かなきゃなあと思いながらブログを書くと、構成が自然と論文風になってしまいますね。関連研究関連研究を述べます。Elgammal による肌色検出のチュートリアル [Encyclopedia of Biometrics, 2009] では、肌色領域の検出の方法について説明しています。そこでは、あらかじめ「こういう色が肌色です」と定義しておいて、それをもとに画像から肌色領域を検出すると
Extracting images from scanned book pages
I work on a project which has placed a number of books online. Over the years we've improved server performance and worked on a fast, responsive viewer for scanned books to make our books as accessible as possible but it's still challenging to help visitors find something of interest out of hundreds of thousands of scanned pages. Trevor and I have discussed various ways to improve the situation an
So I Suck At 24: Automating Card Games Using OpenCV and Python | Arnab Nandi
So I Suck At 24: Automating Card Games Using OpenCV and Python Disclaimer: My area of research is databases. This post is about computer vision, something that I am not an expert at. Please consider this an amateur for-fun-only post! A friend introduced me to the game 24, a simple game you can play with a deck of playing cards. Over the course of playing the game, I realized that either my friend
Face Tracking with OpenCV and a USB Missile Launcher - AlexNisnevich.blog
Check out Sentinel for Linux, Windows, and OS X on GitHub I recently got my roommate a Dream Cheeky Thunder USB missile launcher. It was fun to play around with for a bit, but the included software was very limited in its functionality. Just when I was ready to dismiss it as an overpriced toy, my roommate came up with a great idea: could we mount a camera to the turret and make it automatically ai
