Letter 1

This book chapter describes the system we've had about 2 years ago. Still, most of the components should be similar in terms of general functionality.

This chapter looks at the spatial modeling subsystem.

And if you'd like to know more about the place classification algorithm we used there, look at this:

Regarding the portable device project, I forgot to say that I wanted to try both the device produced by Mårten's brother and Android phones as the sensors for the system and "simulate" robot's sensors by using the camera, compass and accelerometer. To learn more about this idea see:

The place map project (topological mapping) is very very roughly described here:

Letter 2

David G. Lowe, "Distinctive image features from scale-invariant keypoints," International Journal of Computer Vision, 60, 2 (2004), pp. 91-110.

For both, there are binaries as well, so feel free to download it, grab some images and apply the code to the images to see the detected features!

There is an example code in Matlab, you can play with it and actually classify something with BOW.

One of the early papers on BOW could be this, skip all the pLSA, LDA talk.
