Core library functionality concerned with general programming problems rather than multimedia specific functionality. Includes I/O utilities, randomisation, hashing and type conversion.

Core definitions of images, pixels and connected components. Also contains interfaces for processors for these basic types.

Methods for the extraction of local features. Local features are descriptions of regions of images (SIFT, ...) selected by detectors (Difference of Gaussian, Harris, ...).

Implementations of various image, pixel and connected component processors (resizing, convolution, edge detection, ...).

Reusable wrappers and helpers to access and create sequence-files and map-reduce jobs.

Mathematical implementations including geometric, matrix and statistical operators.

Various video processing algorithms, such as shot-boundary detection.

A port of Stan Birchfield's Kanade-Lucas-Tomasi tracker to OpenIMAJ. See http://www.ces.clemson.edu/~stb/klt/.

Various clustering algorithm implementations for all primitive types including random, random forest, K-Means (Exact, Hierarchical and Approximate), ...

Core support for the Resource Description Framework (RDF), including object-rdf mapping.

Implementations of various audio processors (e.g. multichannel conversion, volume change, ...).
