PII: S0262-8856(02)00136-1 - TCASM.pdf. Bioidiap/bob.ip.flandmark. Software. Face Analysis SDK. This section outlines the non-rigid face registration program face-fit.

Face Analysis SDK

This program can perform fitting on a single image, a sequence of images or video. An important detail of the fitting algorithm is that it relies on a frontal face detector to initialize the non-rigid fitting component. Once initialized, it falls back to the frontal face detector only when the fitting algorithm has failed to accurately perform non-rigid registration. The following command executes the fitting algorithm on a single image and visualises the results.

Introduction. Asmlib-opencv - an ASM(Active Shape Model) implementation by C++ using opencv 2. An open source Active Shape Model library written by C++ using OpenCV 2.0 (or above), no other dependencies.

Thanks to CMake, the library has been successfully compiled in following environments: Linux (both 32 and 64 bits) Windows(both VC and MinGW) Mac OS X Android Both training and fitting codes are provided. For Windows users, a binary demo is available for download. The library implements ASM and BTSM(Bayesian Tangent Shape Model). I think its result is good for most frontal faces. With the code provided, you can also train your own model all by yourself (see BuildModel).

Codes are in the SVN repository, click "Source" to check them out. If you have questions, please either file a issue or contact me directly (cxcxcxcx, gmail). Cascade Classifier. Goal In this tutorial you will learn how to: Use the CascadeClassifier class to detect objects in a video stream.

Facial feature detection

It does however require you to give it a bounding box of the face so you will probably have to use the Viola Jones face detector in OpenCV (or any other method) to locate the face first, which you are already doing. I've compiled the code on Ubuntu and it works very well, provided the bounding box you give it is "just right".

Instead of scanning an image or image region for the location of a facial point, it can use every location in a point's neighbourhood to predict where the target point is relative to that location. This considerably speeds up point detection. A comparative study on illumination preprocessing in face recognition.

Asked Jul 12 '12 coredumped3 ● 1 ● 2 Hello, I'm currently doing some work in face recognition with small training data samples (typically only one per person).

videofacerec.py example help

I was initially trying to do face recognition with eigenfaces but getting terrible results, and was guided to use Local Binary Patterns Histograms by this stack overflow post: I started to study the libfacerec as suggested and tried to use the facerec_lbph.cpp example which uses the Local Binary Patterns Histograms to recognize faces. However, my results were still very poor. I must admit, I'm quite new to python, and the fact that there isn't much documentation on this particular example, I'm having trouble making it work. Currently if I try running it in its original code (The only thing I changed was making so instead of capturing frames from a video file, it captures from a live camera feed) it simply does not detect any faces..

Whitening - Ufldl. From Ufldl Introduction We have used PCA to reduce the dimension of the data.

Whitening - Ufldl

There is a closely related preprocessing step called whitening (or, in some other literatures, sphering) which is needed for some algorithms. If we are training on images, the raw input is redundant, since adjacent pixel values are highly correlated. The goal of whitening is to make the input less redundant; more formally, our desiderata are that our learning algorithms sees a training input where (i) the features are less correlated with each other, and (ii) the features all have the same variance.

C++ - Facial Feature Points Detection using OpenCV. Visual Information Processing and Learning. Research topic #5: Lighting Preprocessing Lighting preprocessing aims at achieving illumination-insensitive face recognition by removing uneven illumination (e.g. shadow, underexposure, and overexposure) that appears in face images. Our work on lighting preprocessing includes four main approaches: 1) Image enhancement based methods.

UFLDL Tutorial - Ufldl. From Ufldl Description: This tutorial will teach you the main ideas of Unsupervised Feature Learning and Deep Learning. By working through it, you will also get to implement several feature learning/deep learning algorithms, get to see them work for yourself, and learn how to apply/adapt these ideas to new problems. This tutorial assumes a basic knowledge of machine learning (specifically, familiarity with the ideas of supervised learning, logistic regression, gradient descent). If you are not familiar with these ideas, we suggest you go to this Machine Learning course and complete sections II, III, IV (up to Logistic Regression) first.

Google's Secretive DeepMind Start-up Unveils A "Neural Turing Machine" One of the great challenges of neuroscience is to understand the short-term working memory in the human brain.

At the same time, computer scientists would dearly love to reproduce the same kind of memory in silico. Today, Google’s secretive DeepMind startup, which it bought for $400 million earlier this year, unveils a prototype computer that attempts to mimic some of the properties of the human brain’s short-term working memory. The new computer is a type of neural network that has been adapted to work with an external memory. The result is a computer that learns as it stores memories and can later retrieve them to perform logical tasks beyond those it has been trained to do.

Deep Learning, NLP, and Representations - colah's blog. LUO, Ping (羅平) Cvpr12_facealignment.pdf. Aligning face images. Some people have asked me how I've aligned the face images in my articles. Giving people my ImageMagick hack is embarrassing for me, so I've decided to rewrite it into a Python script.

You don't need to copy and paste it, as the script comes with the source folder of my Guide on Face Recognition: crop_face.py. The code is really easy to use. To scale, rotate and crop the face image you just need to call CropFace(image, eye_left, eye_right, offset_pct, dest_sz), where: eye_left is the position of the left eyeeye_right is the position of the right eyeoffset_pct is the percent of the image you want to keep next to the eyes (horizontal, vertical direction)dest_sz is the size of the output image If you are using the same offset_pct and dest_sz for your images, they are all aligned at the eyes.

Next, let's derive the backward propagation algorithms for these two layer types. Convolutional Layers Let's assume that we have some error function, E, and we know the error values at our convolutional layer.

What, then, are the error values at the layer before it, and what is the gradient for each weight in the convolutional layer? Note that the error we know and that we need to compute for the previous layer is the partial of E with respect to each neuron output (∂E∂yℓij). Let's first figure out what the gradient component is for each weight by applying the chain rule. Neural networks [9.3] : Computer vision - parameter sharing.
