IPipeline: a development framework for image processing pipelines. Abstract : Developing an image processing or computer vision application typically involves the sequencing of a number of elementary operations on images.
Some operations can be simple image processing, other operations will be arithmetic and others will be more advanced function. In most cases, a tool like OpenCV ( provide optimized and efficient implementations, but in some cases, specialized functions also need to be implemented. During the development phases, it can sometimes be useful to visualize all the intermediary output and input, or even to create some debugging visualizations that require creating temporary images. An additional requirement of the development phase is to design modules that can very clearly check if their input correspond to their expectations in terms of size, color depth, pixel format.
Seib2016ARS. Donkey Car - Home. MonsterBorg - The Ultimate Raspberry Pi Robot. Our latest Kickstarter success has finally arrived in our store!
The MonsterBorg is a beast of a kit designed to be taken off road or driven autonomously, it's also our primary racing robot for Formula Pi. The MonsterBorg can be programmed as a self-driving robot, used for education about self-driving systems, or raced around the garden as an RC off-roader. It also makes a great platform for hacking about with robots by adding extra sensors or servos. Features: Up to three hours runtime!

There is a lot of satisfaction you can obtain if you can get a robot to perform simple tasks or even the process of constructing them. Although it may seem like you will need immense amount of studying to create your own robot, thankfully there are robot kits that allow you to build them even without much knowledge about robots. These kits are great if you have a hobby of building things or even if you are looking for project ideas to do your final year project in your college engineering degree.
It is also a great learning experience as you will be able to understand the basic principles and parts used in building robots. Here are a few of the best robot kits that you can purchase. 1. New robot kit series - STEM / DIY educational programmable electronic robot kit. Global Shutter Camera Board. Most of the DSLR cameras and mobile phone’s cameras are using Rolling Shutter technology including Canon, Nikon and iPhones, while industry cameras are using Global Shutter technology.
Why cameras are so different, let’s take a look at the facts of these two kind of technology. Rolling Shutter, usually found in CMOS sensors is a method of capturing image that does not expose the entire sensor pixels simultaneously, actually it exposures line by line from top to bottom. Rather than the rolling shutter camera, global shutter camera exposures all pixels at the same time. The shutter opens at a certain of time then closed, blocking the light enter into the sensor.

Snap! (Build Your Own Blocks) 4.0. Poppy Project - Open source robotic platform. Lego permet aux enfants de contrôler leurs robots depuis un smartphone. CES 2016 - La célèbre marque de jouets lance une nouvelle version de son kit de robotique à destination des écoliers et de leurs enseignants.
Pas besoin de tournevis ou ni de boulons pour construire de véritables robots. À l'occasion du CES, le salon de l'électronique grand public qui se tient chaque année à Las Vegas, Lego a dévoilé la dernière version de WeDo, un kit de robotique spécialement dédié aux écoliers. Outre les briques colorées classiques, il comprend un petit moteur, des capteurs et un bloc intelligent qui relie la machine à une tablette ou un ordinateur (iOS, Android, PC ou Mac) grâce à une connexion Bluetooth. Ses utilisateurs peuvent construire un robot selon des instructions ou leur imagination, puis leur faire réaliser un certain nombre de tâches. Javascript Accelerometer Demo and Source. IOS 4.2 (with new Safari Mobile) has the possibility to read sensor data like accelerometer and gyroscope directly from Javascript.
New Javascript objects and event handler From javascript point of view, we have: new handler window.ondevicemotionnew event object: event.accelerationGravity, with x, y, z attributesevent.accelerationIncludingGravity, with x, y, z attributesevent.rotationRate, with alpha, beta, gamma attributes Code Snip window.ondevicemotion = function(event) { var accelerationX = event.accelerationIncludingGravity.x; var accelerationY = event.accelerationIncludingGravity.y; var accelerationZ = event.accelerationIncludingGravity.z; }
How to capture webcam video with HTML5. HTML5 is fast becoming the developer tool of choice, moving away from heavy Flash apps, and switching to a fast, lightweight solution.
A new generation of web interaction is coming, where users are able to play full games in their browser without a hint of Flash. Typically, interacting with a user’s webcam required a third-party application or a Flash component, but now we can access this data via the cutting-edge HTML5 technology known as getUserMedia. As with anything this new and exciting there are bound to be some teething problems, the main one is the cross-browser compatibility of getUserMedia. It is recommended that you use the latest version of Chrome as most other browsers simply won’t work. Introducing TCP Listen, a new API for Chrome packaged apps. Chrome packaged apps aim to deliver an app experience with the appearance and capabilities of native apps, but built using the growing capabilities of HTML5.
These apps can access APIs for better filesystem handling, direct access to hardware devices, raw network communication and many others. One of the new APIs that just landed in an experimental state is TCP Listen, which allows an app to accept incoming TCP connections. Advancements In Connecting To ROS Via Web With The Rosbridge Suite. During his internship at Willow Garage, Jonathan Mace from Brown University worked on building an industrial strength successor to rosbridge, a popular ROS package for connecting to ROS from a Web browser.
His internship concluded with the release of the rosbridge suite, a robust and extensible collection of packages that facilitate Web-based and non-ROS connection to ROS. Web browsers are a compelling choice for writing front ends to robot applications. In particular, they offer a ubiquitous, interoperable platform for robot interaction. WebTCP: Making TCP connections from Browser - Artem Yankov. The problem There is no simple way to create TCP sockets in Javascript on a browser side. Although solutions like Websockets allow to create something that resemble sockets, you can use them to connect only to servers that support Websockets.
Not to any random servers that know nothing about HTTP. Why bother.
