Face Subspace Learning (Face Image Modeling and Representation) (Face Recognition) Part 3. Related Works Applying the idea of manifold learning, that is, exploring local geometry information of data distribution, into semisupervised or transductive subspace selection leads to a new framework of dimension reduction by manifold regularization.
One example is the recently proposed manifold regularized sliced inverse regression (MRSIR) . Sliced inverse regression (SIR) was proposed for sufficient dimension reduction. In a regression setting, with the predictors X and the response Y, the sufficient dimension reduction (SDR) subspace B is defined by the conditional independency Y±X | BTX. Under the assumption that the distribution of X is elliptic symmetric, it has been proved that the SDR subspace B is related to the inverse regression curve E(X | Y).

You give it an image of a face and it returns the positions of the facial features. Stasm is designed to work on front views of faces with neutral expressions. It performed very well in an independent 2013 comparative study. Active Shape Models with Stasm. TCASM.pdf. Nonparametric Context Modeling of Local Appearance for Pose- and Expression-Robust Facial Landmark Localization. Abstract We propose a data-driven approach to facial landmark localization that models the correlations between each landmark and its surrounding appearance features.
At runtime, each feature casts a weighted vote to predict landmark locations, where the weight is precomputed to take into account the feature's discriminative power.

A group sparse learning method is proposed to automatically select the optimized anchor points. We set up weights for each landmark patch in the part mixture model indicating the likelihood of choosing these parts. By regularizing the weights group sparse, maximizing the margin over positive and negative training samples generates effective weights to simplify the mixtures of parts. Publication X.

In this tutorial we will describe a simple benchmark for this competition, written entirely in R.
R is a free software programming language, used widely for statistical computing. It is available for Windows, OS X, Linux and other platforms, and is a favorite amongst Kaggle competitors tools. The competition The goal of the competition is to locate specific keypoints on face images. You should build an algorithm that, given an image of a face, automatically locates where these keypoints are located. Download and extract the data First you'll need to get the data. Reading the data into R If you haven't done so yet, install R. Now launch R. Computer Vision Source Code. Matthias Dantone, computer vision.

Matthias Dantone, Juergen Gall, Gabriele Fanelli, Luc van Gool Abstract lthough facial feature detection from 2D images is a well-studied field, there is a lack of real-time methods that estimate feature points even on low quality images. Here we propose conditional regression forest for this task. While regression forest learn the relations between facial image patches and the location of feature points from the entire set of faces, conditional regression forest learn the relations conditional to global face properties.
Images and Video video [14 MB, DivX Movie] Face Detection Matlab Code. We present a unified model for face detection, pose estimation, and landmark estimation in real-world, cluttered images.
Our model is based on a mixtures of trees with a shared pool of parts; we model every facial landmark as a part and use global mixtures to capture topological changes due to viewpoint. We show that tree-structured models are surprisingly effective at capturing global elastic deformation, while being easy to optimize unlike dense graph structures. We present extensive results on standard face benchmarks, as well as a new "in the wild" annotated dataset, that suggests our system advances the state-of-the-art, sometimes considerably, for all three tasks.
