03 Feb 2012 Fundamental Matrix Computation This package, implements the 3 standard algorithms for the computation of the fundamental matrix. Author: Omid Aghazadeh

Fundamental matrix estimation is equivalent to estimating the image of the other camera in the other one; therefore if the view points of the cameras wrt eachother change, different fundamental matrices will describe the relation between the two cameras. See http://en.wikipedia.org/wiki/Epipolar_geometry.

Hi Ran,
It seems that what you're looking for is a method to compute the Essential matrix. Fundamental matrix will allow uncalibrated reconstruction which would have a projective ambiguity. For a metric reconstruction with scale ambiguity, you will need calibrated cameras and the Essential matrix.
Hope it helped,
Omid

you need to get the size of the original image and not that of the result.
15 Jul 2010 Nonlinear Coupled Diffusion This package implements isotropic nonlinear scalar valued/ coupled vector/matrix valued diffusion. Author: Omid Aghazadeh

I encountered the same problem in linux. It seems that gcc is sensitive to the signiture of the mexFunction having a const for the prhs parameter:
in the mex file, change the header to :

void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
....
}

The mex function is as simple as it gets, a few multiplications and additions and I'm sure that it compiles using Microsoft Visual Studio 2008 c++ compiler. I'm not sure what the problem is but it might be the lcc compiler. Maybe you can try gnu compiler or MSVC c++ compiler.

08 May 2013 Nonlinear Coupled Diffusion This package implements isotropic nonlinear scalar valued/ coupled vector/matrix valued diffusion. Author: Omid Aghazadeh Xizhi

It works well despite of low speed. I am trying to figure out the way to de-noise color image using edge enhancing diffusion while the referenced literature are a bit confusing to me.

15 Nov 2012 Fundamental Matrix Computation This package, implements the 3 standard algorithms for the computation of the fundamental matrix. Author: Omid Aghazadeh Sarhat

Why the x1 and x2 vector is 3XN (cause iam confused in this I have a mtaching points from both images (x1,y1 and x2 y2) there is no z with the matching points. except if I want to include the focal length in that case I will put in z component 1 if it is not available. Do I am right or not?
