| The release 1.2.0 of the Bob signal-processing and machine learning toolbox is available . Bob provides both efficient implementations of several machine learning algorithms as well as a framework to help researchers to publish reproducible research.
The previous release of Bob was providing: * image, video and audio IO interfaces such as jpg, avi, wav, * database accessors such as FRGC, Labelled Face in the Wild, and many others, *mage processing: Local Binary Patterns (LBPs), Gabor Jets, SIFT, * machines and trainers such as Support Vector Machines (SVMs), k-Means, Gaussian Mixture Models (GMMs), Inter-Session Variability modeling (ISV), Joint Factor Analysis (JFA), Probabilistic Linear Discriminant Analysis (PLDA), Bayesian intra/extra (personal) classifier, The new release of Bob has brought the following features and/or improvements, such as: * Unified implementation of Local Binary Patterns (LBPs), * Histograms of Oriented Gradients (HOG) implementation, * Total variability (i-vector) implementation, * Conjugate gradient based-implementation for logistic regression, * Improved multi-layer perceptrons implementation (Back-propagation can now be easily used in combination with any optimizer -- i.e L-BFGS), * Pseudo-inverse-based method for Linear Discriminant Analysis, * Covariance-based method for Principal Component Analysis, * Whitening and within-class covariance normalization techniques, * Module for object detection and keypoint localization (bob.visioner), * Module for audio processing including feature extraction such as LFCC and MFCC, * Improved extensions (satellite packages), that now support both Python and C++ code, within an easy to use framework, * Improved documentation and add new tutorials, * Support for Intel's MKL (in addition to ATLAS), * Extend supported platforms (Arch Linux). This release represents a major milestone in Bob with plenty of functionality improvements (>640 commits in total) and plenty of bug fixes. • Sources and Documentation • Binary packages: • Ubuntu: 10.04, 12.04, 12.10 and 13.04 • For Mac OSX: works with 10.6 (Snow Leopard), 10.7 (Lion) and 10.8 (Mountain Lion) For instructions on how to install pre-packaged version on Ubuntu or OSX, consult our quick installation instructions (N.B. OS X macport has not yet been upgraded. This will be done very soon. cf. https://trac.macports.org/ticket/39831 ).
