Where are we?

I learned this week the breadth of coordinate systems that are used to geolocate a “point” on the surface of the earth. A very nice archeological survey was done of the Skalanes peninsula about 10 years ago (as near as I can tell, it is in Icelandic). The locations of the features they catalog are given in eastings and northings from a point that I have not found documented yet. It appears to be UTM but when you use 28 W, the UTM grid zone for eastern Iceland you get kind-of-sort-of close, say within a couple of Km, but nowhere no exact. The survey team used a differential GPS, if we can obtain a copy of their database we should be able to figure-out how to convert from their coordinate system.

In other news Gail and I have finished making the hostel, ferry, and car reservations. Next up is exploring bulk airfare.

What do our computer eyes see?

Ive begun stepping into the world of machine learning algorithms, Kellan has been helping with some of the mathematical aspects which has made debugging a breeze. This post is going to be a bit image heavy so take it easy and look through some of the results!

This first two images are SIFT based implementations. With the Lupin plant targeted in the

The next is based on SURF and is targeting the rocks in the image. Parts of the bridge is ‘found’ but mostly due to the similarities in pixel colours. This can be worked out eventually.

We’re back…

After a bit of a break from blogging we’re back. Nic and I have been puddling along with image analysis, LiDAR and the ambiance platform over the past couple of months. Recently Kellan joined us working on machine learning/feature extraction (she is also a part of the group that will be traveling to Iceland with us). Gail and I have been busy on the logistics side, we have van & car reservations, ferry tickets to Heimaey, and a few of our hostel reservations done. We have also been working with Oli on the details related to Skalanes and Gummi (Colder Climates) about the glacier work and a hike to the Laki craters.
