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.
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.
Engauge Digitizer is digitizing software that converts an image showing a graph or map into numbers. The image file can come from a scanner, digital camera, or screenshot. The numbers can be read on the screen, and written or copied to a spreadsheet. Highlights for beginners include an intuitive interface and extensive context-sensitive documentation. Highlights for experts include compensation for image distortion, cartesian and polar coordinates, linear and logarithmic coordinates, automatic scanning, graphical previews, and browser help.
Autopano-SIFT is a helper program for panorama image generation. It automatically generates control point information for a number of image files for use with the hugin panorama generation software. To do this, it utilizes the SIFT (Scale-Invariant Feature Transform) algorithm, a sophisticated image feature matching algorithm.
Moron (Method for Object Recognition of Obscure Nature) is a tool to classify given images based on their content. Technically, it combines feature extraction and machine learning. The classes recognized depend on the version. A typical Moron version tries at least to separate drawn content from photographs (pron) and thus could be adapted as a spam filter for cartoon newsgroups.
ImLib3D is a C++ library and visualization system for 3D (volumetric) image processing. It contains most basic image processing algorithms, as well as some more sophisticated ones. Its images are STL-compliant templated containers. It inculdes a viewer that features multiplanar views, interactive image processing, animations, vector field views, and 3D (OpenGL) multiplanar. Its main application is medical image processing.
