libCVD is a very portable and high performance C++ library for computer vision, image, and video processing. The emphasis is on providing simple and efficient image and video handling and high quality implementations of common low-level image processing function. The library is designed in a loosely-coupled manner, so that parts can be used easily in isolation if the whole library is not required. The video grabbing module provides a simple, uniform interface for videos from a variety of sources (live and recorded) and allows easy access to the raw pixel data. Likewise, the image loading/saving module provides simple, uniform interfaces for loading and saving images from bitmaps to 64 bit per channel RGBA images. The image processing routines can be applied easily to images and video, and accelerated versions exist for platforms supporting SSE.
The main goal of the Cognitive Vision project is to improve the results of artificial intelligence. The current scope is to equip the abilities of the AIBO (robot dog of the Sony) to explore its environment and to recognize the local position (e.g. navigation in a room). The first trial is to use and develop image processing methods with a single webcam and to apply these techniques with AIBO.
Qastrocam is a capture program that can work with any video4linux device. Its main purpose is to do astrophotography. It can control a telescope to do guiding with the images received from the video device. It can also control the extended features of a webcam modified to do long exposure (several seconds) captures.
GL2PS is a C library providing high quality vector output for any OpenGL application. It uses sorting algorithms capable of handling intersecting and stretched polygons, as well as non manifold objects. It provides advanced smooth shading and text rendering, culling of invisible primitives, mixed vector/bitmap output, and much more. It can currently create PostScript (PS), Encapsulated PostScript (EPS), Portable Document Format (PDF), and Scalable Vector Graphics (SVG) files, as well as LaTeX files for the text fragments.
unicap is a library to access different kinds of capture devices. Device drivers are loaded with a plugin system so that new drivers can be easily added. Currently, it has support for video-4-linux, video-4-linux-2, IIDC cameras, and video-to-firewire converters, and provides GTK widgets for live video display and access to device properties.
Qtpfsgui is an open source graphical user interface application that aims to provide a workflow for HDR imaging. Supported operations include: creations of a HDR file from a set of images of a scene taken at different exposure settings, tone-mapping an HDR image into a common LDR image format (e.g JPEG or PNG), and loading, saving, and rotating existing HDR images.
EZFB is a polymorphic, object oriented Linux frame buffer API written in C, designed to adapt at run time to control any properly configured Linux frame buffer video system. It offers independent, simultaneous control of multiple video cards within a single system, exceptional control of colors, the ability to display all or portions of bitmap files anywhere on the screen, automatic color depth conversion, the ability to capture to bitmap files, an 8x8 bitmapped font, routines to draw points, lines, outlined and filled rectangles, signal trapping for automatic screen clean-up at process termination, and much more. The demonstration applications include a bitmap viewer, screen capture utility, screen saver, and a touch screen calibration utility and an application for generating, viewing, transforming, and saving files according to The International Laser Display Association's ILDA file format.
