Computer Vision: Algorithms and Applications

Computer Vision: Algorithms and Applications
© 2010 Richard Szeliski Welcome to the Web site ( for my computer vision textbook, which you can now purchase at a variety of locations, including Springer (SpringerLink, DOI), Amazon, and Barnes & Noble. The book is also available in Chinese and Japanese (translated by Prof. Toru Tamaki). This book is largely based on the computer vision courses that I have co-taught at the University of Washington (2008, 2005, 2001) and Stanford (2003) with Steve Seitz and David Fleet. You are welcome to download the PDF from this Web site for personal use, but not to repost it on any other Web site. The PDFs should be enabled for commenting directly in your viewer. If you have any comments or feedback on the book, please send me e-mail. This Web site will also eventually contain supplementary materials for the textbook, such as figures and images from the book, slides sets, pointers to software, and a bibliography.

Understanding Convolution in Deep Learning Convolution is probably the most important concept in deep learning right now. It was convolution and convolutional nets that catapulted deep learning to the forefront of almost any machine learning task there is. But what makes convolution so powerful? How does it work? Sebastian Thrun's Homepage Sebastian Thrun and Lorien Y. Pratt Kluwer Academic Publishers Over the past three decades, research on machine learning and data mining has led to a wide variety of algorithms that induce general functions from examples.

Nicolas Burrus Homepage - Kinect Calibration Calibrating the depth and color camera Here is a preliminary semi-automatic way to calibrate the Kinect depth sensor and the rgb output to enable a mapping between them. You can see some results there: It is basically a standard stereo calibration technique ( the main difficulty comes from the depth image that cannot detect patterns on a flat surface.

Python Numpy Tutorial This tutorial was contributed by Justin Johnson. We will use the Python programming language for all assignments in this course. Python is a great general-purpose programming language on its own, but with the help of a few popular libraries (numpy, scipy, matplotlib) it becomes a powerful environment for scientific computing. We expect that many of you will have some experience with Python and numpy; for the rest of you, this section will serve as a quick crash course both on the Python programming language and on the use of Python for scientific computing. Some of you may have previous knowledge in Matlab, in which case we also recommend the numpy for Matlab users page. Table of contents:

Open source code chat bots Powered by Translate Open source chat bots Windows Kinect Driver/SDK - CL NUI Platform Preview Hi Alex, and thank you for your work, was waiting for something like that, I installed the sdk and demo. If anybody is goin to run into problems like described below, maybe you have installed previoulsy another version of NUI devices, so You need to remove all the software, then, from device manager, unistall and remove driver software for all the 3 NUI devices, reinstall CL sdk, and have fun :D // Crash case When starting the application I got a crash, if i do not stop the application i can see the GUI, control the motors&led and read accelerometer values, but i got black textures. it stops with this message :

Where to Learn Deep Learning – Courses, Tutorials, Software Deep Learning is a very hot Machine Learning techniques which has been achieving remarkable results recently. We give a list of free resources for learning and using Deep Learning. By Gregory Piatetsky, @kdnuggets, May 26, 2014. Deep Learning is a very hot area of Machine Learning Research, with many remarkable recent successes, such as 97.5% accuracy on face recognition, nearly perfect German traffic sign recognition, or even Dogs vs Cats image recognition with 98.9% accuracy. Imperial Computer Vision and Learning Lab EE462, EE9SO25, EE9CS728: Machine Learning for Computer Vision Course Aims • The course aims to introduce the concepts, theories and state-of-the-art algorithms for visual learning and recognition. The first half of the module, for formulations and theories of machine learning techniques, consists of clustering, discriminative classifier learning, and probabilistic generative models. The latter half leads to the topics of visual recognition by the machine learning techniques learnt, including object detection/categorisation, segmentation, face and pose recognition.

Creating a Chat Bot — Free Code Camp Human interaction has always fascinated me: social awkwardness, communication style, how knowledge is transferred, how relationships are built around trust, story telling and knowledge exchange. What if a machine invoked an emotional response? First the back story I want to write about a project I have been working on, and how it has engulfed the last few years of my life, but ultimately, this post is about creating a real chat bot. Kinect - OpenSource [News] - amazing work created within a few days.. #of There have been a number of exciting developments in the last few days related to XBox Kinect. For those that may not be aware of what it is, it’s a brand new interface to their Microsoft XBox games console. Kinect brings games without using a controller. By using projected infra-red light, the device is able to map the environment and via xbox built in software recognise gestures of any kind (see video below). Only few hours after the worldwide release of Kinect, guys at NUI Group, who posted results first, planed to only release the driver as open source once their $10k donation fund was filled up.

Caffe Tutorial Caffe is a deep learning framework and this tutorial explains its philosophy, architecture, and usage. This is a practical guide and framework introduction, so the full frontier, context, and history of deep learning cannot be covered here. While explanations will be given where possible, a background in machine learning and neural networks is helpful. Philosophy
