Computes the fundamental matrix from 8 or more matching points in a stereo pair of images using the normalized 8 point algorithm. The normalized 8 point algorithm given by Hartley and Zisserman is used. To achieve accurate results it is recommended that 12 or more points are used. The code uses the normalise2dpts.m file also provided.

Please note that the code requires OpenCV version 1.0 (April Edition) to be installed on the target system. The package includes sample stereo images together with the correspondence points.

The EDISON system contains the image segmentation/edge preserving filtering algorithm described in the paper Mean shift: A robust approach toward feature space analysis and the edge detection algorithm described in the paper Edge detection with embedded confidence. There is also Matlab interface for the EDISON system at the below link.

The KDE class is a general matlab class for k-dimensional kernel density estimation. It is written in a mix of matlab ".m" files and MEX/C++ code. Thus, to use it you will need to be able to compile C++ code for Matlab. The kernels supported are Gaussian, Epanetchnikov and Laplacian. There is a detailed instruction about how to use it at http://www.ics.uci.edu/~ihler/code/kde.html
The goodness of this code is that it provides the options, such as 'distance measure', 'emptyaction', and 'onlinephase'. It is quit slow when dealing with large datasets and sometimes memory will be overflow.
This code uses the JIT acceleration in Matlab, so it is much faster than k-means in the Statistics Toolbox. It is very simple and easy to read.
This code calls the c code of k-means. It is the fastest one among these three and can deal with large dimensional matrix.
You can find the code for data clustering and image segmentation at http://www.cis.upenn.edu/~jshi/software/, wich was provided by Jianbo Shi.
For instructions on using the code please refer to the readme.txt file included in the zip package. Note the code requires OpenCV and fltk (an open source window toolkit) to be installed on the target system.

Brox and Sand Methods (matlab)
This code implements a variation of
the paper "High accuracy optical flow using a theory for warping", presented
at ECCV 2004. Details of implementation, especially the numerics, have been
adapted from the PhD thesis of Dr. Thomas Brox. Extension to different color
channels, and the concept of a local smoothing function, has been adopted
from the PhD thesis of Dr. Peter Sand.

There have been various changes made to the code since the initial publication. Some subtle, some not so subtle. The most significant change is the use of a tessellation method to calculate the orientation bins. Our testing has shown improved results; however, currently rotational invariance has not been re-implemented. Rotational invariance is useful in certain applications, however it is useless in others, for this reason we have focused our time elsewhere. Another noteable change is the elimination of some points due to lack of descriptive information (multiple gradient orientations). This is a change which has a flag, and can therefore be turned on or off, however I suggest leaving it on and writing your frontend in such a way that allows 3DSIFT to refuse points, as this too has proven very effective in our testing.
Please see the README file for more detailed and up-to-date information.

SPatiotemporal REgularity Flow (SPREF) is a new spatiotemporal feature that represents the directions in which a video or an image is regular, i.e., the pixel appearances change the least. It has several application, such as video inpainting and video compression. For more detail, please refer to our project page SPREF section.
Fast Registration of Aerial Image SEquences (FRAISE) is a lightweight OpenCV based software system written in C/C++ to register a sequence of aerial images in near-realtime. A demo test video video sequence and an image sequence with corresponding FRAISE alignment are included.
