Contours

• Segmentation of Skin-Cancer Images Implementation of an algorithm for segmenting images of skin cancer and other pigmented lesions (see Image and Vision Computing, January 1999, pp. 65-74).
  An automatic method for segmention of images of skin cancer and other pigmented lesions is implemented. This method first reduces a color image into an intensity image and approximately segments the image by intensity thresholding. Then, it refines the segmentation using image edges. Double thresholding is used to focus on an image area where a lesion boundary potentially exists. Image edges are then used to localize the boundary in that area. A closed elastic curve is fitted to the initial boundary and is locally shrunk or expanded to approximate edges in its neighborhood in the area of focus. Segmentation results from twenty randomly selected images show an average error that is about the same as that obtained by four experts manually segmenting the images. (by L. Xu, M. Jackowski, A. Goshtasby, C. Yu, D. Roseman, S. Bines, A. Dhawan, A. Huntley / Intelligent Systems Laboratory / Wright State University)

• Gandalf Gandalf is a computer vision and numerical algorithm library, written in C, which allows you to develop new applications that will be portable and run FAST. Includes many useful vision routines, including camera calibration, homographies, fundamental matrix computation, and feature detectors (includes source code).

MoKey performs automatic inpainting of moving objects over an image sequence, and can also be used to compute an accurate alpha matte or outline of an object. Gandalf currently contains four packages: 1) Common package of simple structures and routines used by the other packages, such as memory allocation, linked lists and error handling; 2) Linear algebra package with a large number of routines for matrix and vector manipulations; 3) Image package defining a general purpose image structure and low-level image manipulation routines; 4) Vision package containing a number of standard image processing, computer vision and numerical routines. The major design features of Gandalf are: (i) Efficient use of memory through dynamically reconfigurable structures; (ii) Emphasis on support of numerical algorithms, especially optimisation; (iii) A very flexible and efficient internal image representation, (iv) A comprehensive set of matrix/vector operations, incorporating implicit matrix transpose & inverse, and in-place computation where appropriate; Exploitation of the computational and compilation speed advantages of C over C++ in reducing the number of layers of abstraction over the raw data, an approach we believe is appropriate for simple objects such as matrices, vectors and images. The documentation for Gandalf comes in two parts. There is a LaTex tutorial with examples available also in HTML (via Latex2html). Reference documentation for Gandalf has also been generated using ObjectOutline, ( by Philip McLauchlan)

• Modular Flow Scheduling Middleware - An open source, windows-based framework for developing programs with good software engineering qualities. It has been used for developing real-time vision applications.
  Modular Flow Scheduling Middleware is an open source implementation of a generic, modular, extensible software architecture for dataflow processing of datastreams. It provides a framework for the implementation of algorithms and development of applications with desirable software engineering qualities, such as efficiency, scalability, extensibility, reusability, interoperability.

• PicDB - an image database system with query by image content capabilities.
• Real-time Head Tracking - automatic real-time head-tracking in video images. ( vision pearls GbR)
• Renoir - 3D reconstruction from photos - 3D reconstruction from photos. 3D photomontage. ($$ payware $$ - free demo version available). Mainly useful for computer graphics, but uses some computer vision techniques
  Model of an object is created manually from parametric blocks. Corresponding edges are marked on images and model. Camera and model parameters are reconstructed through minimization of distance between projected edges of model and corresponding edges, marked on photos. (by Ildar Valiev / Integra, Inc.)
• RRCapture - a video capture program used to capture uncompressed image sequences using a PC configured with a 1 to 3 Bitflow RoadRunner digital frame grabbers. (by Ross Cutler / Computer Vision Lab / University of Maryland)
• Verifinger - Fingerprint processing and recognition - SDK for fingerprint processing and recognition ( Neurotechnologija Ltd.)
• VisualMouse - Our software translates user's head motion into the motion of the cursor on the screen, by processing the image from a web cam
• Zaxel 3D Imaging Systems - Zaxel's 3D Imaging Systems create an infinite number of virtual cameras around the object or moving subject from a limited number of real camera inputs.
