Tutorial: OpenCV haartraining (Rapid Object Detection With A Cascade of Boosted Classifiers Based on Haar-like Features) - Naotoshi Seo. Tutorial: OpenCV haartraining (Rapid Object Detection With A Cascade of Boosted Classifiers Based on Haar-like Features) Objective The OpenCV library provides us a greatly interesting demonstration for a face detection.
Furthermore, it provides us programs (or functions) that they used to train classifiers for their face detection system, called HaarTraining, so that we can create our own object classifiers using these functions. It is interesting. However, I could not follow how OpenCV developers performed the haartraining for their face detection system exactly because they did not provide us several information such as what images and parameters they used for training. My working environment is Visual Studio + cygwin on Windows XP, or on Linux. Adam Harvey Explains Viola-Jones Face Detection. Adam Harvey is an artist, designer, and programmer in New York.
Facerec_python.pdf (application/pdf-object) Blog:fisherfaces [ Some time ago I have written a post on Linear Discriminant Analysis, a statistical method often used for dimensionality reduction and classification.
It was invented by the great statistician Sir R. A. Fisher, who successfully used it for classifying flowers in his 1936 paper "The use of multiple measurements in taxonomic problems" (The famous Iris Data Set is still available at the UCI Machine Learning Repository.). But why do we need another dimensionality reduction method, if the Principal Component Analysis (PCA) did such a good job? Well, the PCA finds a linear combination of features that maximizes the total variance in data. This was also recognized by Belhumeur, Hespanha and Kriegman and so they applied a Discriminant Analysis to fae recognition in their paper "Eigenfaces vs. You seldomly see something explained with code and examples, so I thought I'll change that. I've put all the code under a BSD License, so feel free to use it for your projects. Algorithmic Description. Blog:gender_classification [ My last post was very long and I promise to keep this one short.
In this post I want to do gender classification on a set of face images and find out which are the specific features faces differ in. Dataset I have used the celebrity dataset from my last post and downloaded images for Emma Watson, Naomi Watts and Jennifer Lopez. So the database has 8 male and 5 female subjects, each with 10 images. Guo's Publications. Gender Classification with OpenCV — OpenCV v2.4.9 documentation. Introduction A lot of people interested in face recognition, also want to know how to perform image classification tasks like: Gender Classification (Gender Detection)Emotion Classification (Emotion Detection)Glasses Classification (Glasses Detection)...

PAMI10Guo.pdf (application/pdf-object) Facial Age Estimation. Facial Age Estimation Age estimation is the determination of a person’s age based on biometric features.
Although age estimation can be accomplished using different biometric traits, this article is focused on facial age estimation that relies on biometric features extracted from a person’s face. The main issues presented in the article involve typical applications where facial age estimation can be used, problem and challenges associated with facial age estimation, typical approaches reported in the literature and future research directions. Problem Definition The appearance of a human face is affected considerably by aging (see Figure 1). Perceptual Computing SDK. Computer Vision:Algorithms and Applications (draft) OpenCV. Opencvsharp - OpenCV wrapper for .NET Framework. Emgu CV: OpenCV in .NET (C#, VB, C++ and more) * Multiple face detection and recognition in real time.
Download FaceRecPro Optimized Version: Source code, Demo: All binaries references, algorithm enhanced - 6.5 MB Introduction The facial recognition has been a problem very worked around the world for many persons; this problem has emerged in multiple fields and sciences, especially in computer science, others fields that are very interested In this technology are: Mechatronic, Robotic, criminalistics, etc.
In this article I work in this interesting topic using EmguCV cross platform .Net wrapper to the Intel OpenCV image processing library and C# .Net, these library’s allow me capture and process image of a capture device in real time. The main goal of this article is show and explains the easiest way how implement a face detector and recognizer in real time for multiple persons using Principal Component Analysis (PCA) with eigenface for implement it in multiple fields.
Background Traditional text taken from  Kinect + Emgu « Geek-Press. Sorry about the inactivity but having and a daytime job and girlfriend sometimes leaves us without time. Started to play with Computer Vision and Kinect, didn't done a big thing but I was completly unaware of how CV works and after reading a while about it I hear that Emgu is a great wrapper for openCV library.
In fact you can do some face detection without any worries at all. So let's do a hands-on on this library For this example you need. Level 3c - How To Improve Face Detection. QUESTION: "Face detection result is not up to my expectations/needs! How do I improve the detection results?! "Simple Solution: Is your problem something like: not all faces are being detected ? SERVOMagazine Series, Seeing with OpenCV. How Face Detection Works. OpenCV's face detector uses a method that Paul Viola and Michael Jones published in 2001. Usually called simply the Viola-Jones method, or even just Viola-Jones, this approach to detecting objects in images combines four key concepts: Simple rectangular features, called Haar features An Integral Image for rapid feature detection The AdaBoost machine-learning method A cascaded classifier to combine many features efficiently The features that Viola and Jones used are based on Haar wavelets. Haar wavelets are single wavelength square waves (one high interval and one low interval).
Face Recognition with OpenCV — OpenCV v2.4.2 documentation. Introduction OpenCV (Open Source Computer Vision) is a popular computer vision library started by Intel in 1999. The cross-platform library sets its focus on real-time image processing and includes patent-free implementations of the latest computer vision algorithms. In 2008 Willow Garage took over support and OpenCV 2.3.1 now comes with a programming interface to C, C++, Python and Android. OpenCV is released under a BSD license so it is used in academic projects and commercial products alike. OpenCV 2.4 now comes with the very new FaceRecognizer class for face recognition, so you can start experimenting with face recognition right away.
Alexandre Alahi - FREAK. - What is the problem? A large number of vision applications rely on matching keypoints across images. The last decade featured an arms-race towards faster and more robust keypoints and association algorithms: SIFT, SURF, and more recently BRISK to name a few. These days, the deployment of vision algorithms on smart phones and embedded devices with low memory and computation complexity has even upped the ante: we need to make descriptors faster to compute, more compact while remaining robust to scale, rotation and noise. - What is our solution? We propose a novel keypoint descriptor inspired by the human visual system and more precisely the retina, coined Fast Retina Keypoint (FREAK). AForge.NET.

OpenCL. CLBenchmark - High-performance compute benchmark for OpenCL 1.1 environment. CUDA. CUDA (Compute Unified Device Architecture) is a parallel computing platform and programming model created by NVIDIA and implemented by the graphics processing units (GPUs) that they produce. CUDA gives program developers direct access to the virtual instruction set and memory of the parallel computational elements in CUDA GPUs.
Using CUDA, the GPUs can be used for general purpose processing (i.e., not exclusively graphics); this approach is known as GPGPU. Unlike CPUs, however, GPUs have a parallel throughput architecture that emphasizes executing many concurrent threads slowly, rather than executing a single thread very quickly. CUDA provides both a low level API and a higher level API. The initial CUDA SDK was made public on 15 February 2007, for Microsoft Windows and Linux. Example of CUDA processing flow 1. Background The GPU, as a specialized processor, addresses the demands of real-time high-resolution 3D graphics compute-intensive tasks. Advantages Limitations eMotion - Facial Expression Recognition.
Finally A TV Ad That Encourages Hand Gestures: Brainient Taps Kinect For Interactive TV Ads. European online video startup, Brainient, whose BrainRolls system enables advertisers to incorporate interactive elements into online video adverts to boost brand engagement and recognition — such as clickable Facebook Like buttons and photo galleries — is tapping into Microsoft’s Xbox Kinect gesture-based controller to push into the connected TV space. Brainient already sells its BrainRolls product for viewing video ads on computers, smartphones and tablets — its system automatically tailors the ad to the type of screen it’s being viewed on, and can therefore offer advertisers the ability to run what is effectively the same campaign across a variety of devices. Today it’s opening a new front with the launch of an interactive video ad that taps up Kinect gestures to extend interactive video ads to connected TVs.
