The toolbox is designed to meet the needs of researchers by reducing development time and e􀀎ciently processing data. Firstly, Bob provides a researcher-friendly Python environment for rapid development. Secondly, e􀀎cient processing of large amounts of multimedia data is provided by fast C++ implementations of identi􀀌ed bottlenecks. The Python environment is integrated seamlessly with the C++ library, which ensures the library is easy to use and extensible. Thirdly, Bob supports reproducible research through its integrated experimental protocols for several databases. Finally, a strong emphasis is placed on code clarity, documentation, and thorough unit testing. Bob is thus an attractive resource for researchers due to this unique combination of ease of use, e􀀎ciency, extensibility and transparency. Bob is an open-source library and an ongoing community e􀀋ort.  \nCategories and Subject Descriptors  \nI.5 [Pattern Recognition]: General; I.4 [Image Processing and Computer Vision]: General  \nGeneral Terms  \nAlgorithms  \nKeywords  \nOpen Source, Signal Processing, Machine Learning, Computer Vision, Pattern Recognition, Biometrics  \nPermission to make digital or hard copies of all or part of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.

INTRODUCTION  \nThe software requirements of researchers are quite unique. Firstly, to perform e􀀋ective research requires a software development environment that allows for rapid prototyping and testing of experimental ideas. Yet at the same time, the implementation of the software must be fast enough to allow the researcher to run experiments on massive amounts of data. This is especially true in research covering the 􀀌elds of multimedia and its applications. Finally, for research, the code needs to be clear and self-explanatory, with minimal dependence on other libraries that obfuscate the details of the implementation.  \nThis paper presents Bob, a free signal processing (SP) and machine learning (ML) toolbox that is designed to meet the needs of researchers described above. Bob provides a researcher-friendly Python environment for rapid development, yet remains e􀀎cient for processing large amounts of multimedia data through the use of fast C++ implementations of identi􀀌ed bottlenecks. Bob is designed with reproducible research in mind, and currently provides an APIto easily query and interface with several database protocols. In particular, several protocols for well-known biometric databases are integrated with the aim of improving the reproducibility and comparability of scienti􀀌c publications. A strong emphasis is placed on code clarity, documentation, and thorough unit testing, with readability and maintainability always preferred over aggressive optimisation.  \nBob has a broad scope in terms of SP that is intended to cover both computer vision and audio processing. In ML, it already includes many tools for dimensionality reduction, clustering, generative modelling, and discriminative classi􀀌cation.
