Research Related Information

Research, being the number one cause of creating a better world so far, is the noble activity Jonas spends his working time pursuing. Research topics covered so far include:

Help Make the World a Better Place!

Since human languages are very loosely defined and hard to get a handle on, one can rarely prove that one's research is correct. This leads to the need for evaluating if humans think your program is working or not. This is annoying, but necessary. If you have time and interest, there might be evaluation projects going on that you as a human can take part in. Stuff I have had evaluated so far include:

Kindhearted and helpful people can go to the evaluations page

Master's Thesis, 2001

I did my masters project at CVAP (Computer Vision and Active Perception Laboratory), which is a part of Nada, KTH. My thesis is available in pdf (gzipped) (2 Mb), though everything except the abstract is in Swedish. Since it is about computer vision, there are a lot of pictures, though. I studied how you can use the extra information in colour images (compared to the grey scale images normally used) when detecting features in images. I concentrated on blob (circles) and ridge (ellipses) detection, in a scale space model (so you can find all sizes of blobs/ridges).

The two main things you can use colour for (that I found) is better contrast (the contrast can be high in one colour channel while still being low in the grey scale image) and filtering irrelevant features if they have the wrong colour.

It was tested in an application which did hand following and gesture recognition. The finger tips and palm are blobs (though on very different scales) and the fingers are ridges, anything that is not skin coloured is probably not a part of the hand. There used to be a video (13 Mb) of the hand recognizer running on input from my feature detection program. Last time I checked, it was still there.

Here are my student essays in Japanology. With only three weeks allotted for doing research, writing and attending endless amounts of seminars, no stunning results were achieved. Everyting is written in Swedish.
