Vision Code

I'm working on making more of my code available, but at the moment I've only released an initial version of my estimation package and the code for FNS and CFNS for Phil Torr's Structure and Motion Toolkit in Matlab. FNS in a method for doing MLE estimation of projective parameters (i.e. parameter vectors that are defined only up to a scale factor). CFNS is the same but allows the incorporation of a constraint on the values that the parameters may take. For a full description of the methods see my parameter estimation page, and please note that this is experimental code, so the comments may not fully match what happens and things like that. Also note that this isn't the code that I actually work with, so I won't find the problems unless you let me know.

 

FNS and CFNS for Phil Torr's Structure and Motion Toolkit

So the code I have is as follows

  • The FNS estimator - in ant_fns.m, just needs to be added to a directory somewhere in your path, Version 1.0
  • The CFNS estimator - in ant_cfns.m, Version 1.0
  • The utility files vectorise.m and froNormalise.m
  • The updated torr_estimateF.m with the two new estimators included. This replaces the old version, but then you may have a newer version than I do, in which case it's not hard to see how to make the changes to your new version by looking at what's in this file. Version 1.0
  • The updated torr_compF_sc.m to test it all (updated meaning the same as for the one above). Version 1.0
  • I'm also working on loading and saving data in XML with Phil's toolkit which means that I've come up with a new version of the torr_tool (the code for which you'll find on the XML code page)

This code is still developing, however, so let me know if you have any problems, and check back every now and again to see that you're still using the latest version. Note that you do need to install Phil's package for any of this to work.

 

Anton's Parameter Estimation Toolkit

This is some of the code I've been writing to test the optimisation algorithms that Wojtek Chojnacki, Mike Brooks, Darren Gawley and I have been working on for the last few years. Please see my parameter estimation page for details about the methods, but for an explanation of the code (and to download it) you need the to go to the toolkit page.

 

Image set data in XML

I'm working on an XML application to store information associated with sets of images in XML. The code to read XML from Matlab is on the help page but it's worth reading the main page for the project to get an idea of what's going on.
