| Dlib is a general purpose cross-platform C++ library designed using contract programming and modern C++ techniques. It is open source software and licensed under the Boost Software License. The introduction contains everything you need to know to get started using the library. However, if you have any questions, comments, or complaints feel free to email me or post in the sourceforge Forums. Major FeaturesDocumentationUnlike a lot of open source projects, this one provides complete and precise documentation for every class and function. There are also debugging modes that check the documented preconditions for functions. When this is enabled it will catch the vast majority of bugs caused by calling functions incorrectly or using objects in an incorrect manner. Lots of example programs are provided I consider the documentation to be the most important part of the library. So if you find anything that isn't documented, isn't clear, or has out of date documentation, tell me and I will fix it. High Quality Portable Code Good unit test coverage. The ratio of unit test lines of code to library lines of code is about 1 to 4. The library is tested regularly on MS Windows, Linux, and Mac OS X systems. However, it should work on any POSIX system and has been used on Solaris, HPUX, and the BSDs. No other packages are required to use the library. Only APIs that are provided by an out of the box OS are needed. There is no installation or configure step needed before you can use the library. See the How to compile page for details. All operating system specific code is isolated inside the OS abstraction layers which are kept as small as possible. The rest of the library is either layered on top of the OS abstraction layers or is pure ISO standard C++. Threading The library provides a portable and simple threading API A message passing pipe for inter-thread and inter-processcommunication A timer object capable of generating events that are regularly spaced in time Threaded objects Threaded functions Parallel for loops A thread_pool with support for futures Networking The library provides a portable and simple TCP sockets API An object to help you make TCP based servers iostream and streambuf objects that enables TCP sockets to interoperate with the C++ iostreams library A simple HTTP server object you can use to embed a web server into your applications A message passing pipe for inter-thread and inter-processcommunication A tool used to implement algorithms using the Bulk Synchronous Parallel (BSP) computing model Graphical User Interfaces The library provides a portable and simple core GUI API Implemented on top of the core GUI API are numerous widgets Unlike many other GUI toolkits, the entire dlib GUI toolkit is threadsafe Numerical Algorithms A fast matrix object implemented using the expression templates technique and capable of using BLAS and LAPACK libraries when available. Numerous linear algebra and mathematical operations are defined for the matrix object such as the singular value decomposition, transpose,trig functions, etc. General purpose unconstrained non-linear optimization algorithms using the conjugate gradient, BFGS, and L-BFGS techniques Levenberg-Marquardt for solving non-linear least squares problems Box-constrained derivative-free optimization via the BOBYQA algorithm An implementation of the Optimized Cutting Plane Algorithm Several quadratic program solvers Combinatorial optimization tools for solving optimal assignment andmin cut/max flow problems as well as the CKY algorithm for finding the most probable parse tree A big integer object A random number object Machine Learning Algorithms Conventional SMO based Support Vector Machines for classification andregression Reduced-rank methods for large-scale classification and regression Relevance vector machines for classification and regression General purpose multiclass classification tools A Multiclass SVM A tool for solving the optimization problem associated with structural support vector machines.

Radial Basis Function Networks Multi layer perceptrons Graphical Model Inference Algorithms Join tree algorithm for exact inference in a Bayesian network. Gibbs sampler markov chain monte carlo algorithm for approximate inference in a Bayesian network. Routines for performing MAP inference in chain-structured, Potts, orgeneral factor graphs. Image Processing Routines for reading and writing common image formats. Automatic color space conversion between various pixel types Common image operations such as edge finding and morphological operations Implementations of the SURF, HOG, and FHOG feature extraction algorithms. Tools for detecting objects in images including a frontal face detector. Data Compression and Integrity Algorithms A CRC 32 object MD5 functions Various abstracted objects representing parts of data compressionalgorithms. Many forms of the PPM algorithm are included. Testing A thread safe logger object styled after the popular Java logger log4j A modular unit testing framework Various assert macros useful for testing preconditions General Utilities A type-safe object to convert between big and little endian byte orderings A command line parser with the ability to parse and validate command lines with various types of arguments and options An XML parser An object that can perform base64 conversions Many container classes Serialization support Many memory manager objects that implement different memory pooling strategies |
