09 Apr 2012 The INface toolbox v2.0 for illumination invariant face recognition Photometric normalization techniques used for achieving illumination invariant face recognition. Author: Vitomir Struc SasiKanth

Great toolbox. However, I think the many normalization and hist-equalization steps in the demos are making the results worse. Maybe you can do away with them.

@Hasheem: There is no specification to the king of image you need to use as feature matching takes place on gray images.

@Diogo: RandStream is a function in the newer versions of MATLAB. Why don't you replace it with the function that is present in the version you are using?

@Sean: You are referring to a function called 'imtransform' which transforms images based on a provided transformation matrix. Affine is only one case where as you said, the last column needs to be 0 0 1. however, you may even provide a full projective 3x3 matrix and pass the argument 'projective' to the function 'maketform'.

Hey Hashem,
That is the reason given by the MATLAB error minimization function for exiting the iterative algorithm. In case it is exiting in the very 1st loop itself, there is something wrong with the input you might be giving.

10 Jan 2011 Modified Hausdorff Distance This function computes the Modified Hausdorff Distance (MHD) as per Dubuisson et al. Author: SasiKanth SasiKanth

An elementary correction has been made to the code in the last line where a 'min' instead of a 'max' has been submitted. Please note the correction.

Nice code and well commented to!

Which version of MATLAB do you use?

An updated version of the file has been submitted with the ~'s replaced. It should be up soon.

Hey,

The '~' is a feature in MATLAB 2010 where you need not specify a variable when you do not need it. You can replace all such instances with any arbitrary variable (say 'tmpx') and the code will run. Be careful not to replace wrong instances of '~' (such as in '~isNaN').

Hope this helps.

02 Oct 2010 Hough Transform for circle detection An optimized Hough transform for circle detection. Author: Peter Bone SasiKanth

Works neatly! Although, wish the program was better commented!
