Orfeo Toolbox (OTB) is a high resolution remote sensing image processing library. It contains a set of algorithmic components which allow the user to capitalize on methodological know how, and therefore use an incremental approach to profit from the results of methodological research. OTB is made of a set of basic elements (a C++ class API) and utilities (independent programs built upon the base API).
SIP provides image processing, pattern recognition, and computer vision routines for SciLab, a Matlab-like matrix-oriented programming environment. SIP is able to read/write images in almost 90 major formats, including JPEG, PNG, BMP, GIF, FITS, and TIFF. It includes routines for filtering, segmentation, edge detection, morphology, curvature, fractal dimension, distance transforms, multiscale skeletons, and more.
SILVERCODERS OCR Server is a server-based optical character recognition (OCR) and PDF conversion solution for enterprises. It is able to perform conversion of printed documents to editable and searchable formats like plain text, RTF, PDF, and HTML, providing highly accurate recognition in 189 languages. It is available as a Linux application or a stand-alone machine, with a fully documented API, very good performance, and flexible licensing rules. It has been designed specifically for the purpose of cooperation with document management systems such as SILVERCODERS DocStorage.
CVL is a library for image and data processing using graphics processing units (GPUs). It is suitable as a base for GPGPU applications. Cvtool is a general-purpose computer vision tool that is based on the CVL library. It works as a filter by reading streams of data from standard input and writing manipulated data and/or analysis results to standard output. Complex analysis tasks can easily be realized in scripts. Many image and video manipulation and analysis functions are included, as well as some advanced computer vision techniques.
The LIRE (Lucene Image REtrieval) library provides a simple way to create a Lucene index of image features for content-based image retrieval (CBIR), which allows searching for similar images. The used features are taken from the MPEG-7 standard: ScalableColor, ColorLayout, and EdgeHistogram. Furthermore, methods for searching the index are provided.
impr is a small and fast image processing library with a simple API. Its functions work mostly on 8-bit image channels, which means that main type is just (u8 *) or (b8 *) for grey and binary images respectively. It was intended for use in real-time processing, so functions are optimized for speed. It supports segmentation (4 and 8-connected), flood fill, filling object holes, downscaling and upscaling (with linear interpolation) by an integer factor, generic implementations of dilate and erode (+image open and close), color space conversions between HSVRGB and YRGRGB, convolutions with Roberts and 2x2 low-pass filters, and common binary image operations.
VXL is a set of portable C++ libraries designed for computer vision research and implementation. Numerics, imaging, and geometry are provided by stand-alone core libraries, with easy to use APIs and sophisticated processing algorithms. Other libraries provide stereo, video, structure from motion, probability modeling, GUI design, classification, robust estimation, feature tracking, topology, 3d imaging, and much more. It is written and used by an international team from academia and industry.
