24 Oct 2014 Visualisation/verification of two-view geometries GUI tool to visualise homography, epipolar geometry, etc., to verify their accuracy. Author: Karel Lebeda

On version 2014b, the epipolar lines are invisible. Don't know why, for some reason the images are shown ABOVE the lines. There's a fix for this, in function showImage, add the following line to the end:
set(lHandle, 'ZData', [1 1]);
That should ensure that the line is visible above the image every time it's not NaN.

There's a known bug, when you try to open an image file which is not in your current directory, it fails to load it. I am sorry, I am working on it... :-(

Hi, no, no extensions so far... There didn't seem to be any interest by anyone, so I left it for now.

26 Sep 2013 Vectorized FIND with 'FIRST' option Find the first non-zero element(s) along row/column - or any other dimension Author: Bruno Luong

Your comment is incorrect, on the 7th line should be:
B=zeros(1,size(A,2));

Position is in format [x;y] and they're by default coordinates of the upper left corner; that can be changed by alignment options. Currently, the only font format it takes is my 'special' one... I thought about making it load some common type, or at least create some font(s) in this format (100 characters is not so much...).

Btw, if raster format with fixed font size is enough for you, I can recommend this: http://www.mathworks.co.kr/matlabcentral/fileexchange/26940-render-rgb-text-over-rgb-or-grayscale-image

Interesting script. Have you developed the simple font any further?
