dc.description.abstract
We describe an image-comparison technique of Heidemann and Ritter [4,5] that
uses image compression, and is capable of: (i) detecting novel textures in a
series of images, as well as of: (ii) alerting the user to the similarity of a
new image to a previously-observed texture. This image-comparison technique
has been implemented and tested using our Astrobiology Phone-cam system, which
employs Bluetooth communication to send images to a local laptop server in the
field for the image-compression analysis. We tested the system in a field site
displaying a heterogeneous suite of sandstones, limestones, mudstones and
coalbeds. Some of the rocks are partly covered with lichen. The imagematching
procedure of this system performed very well with data obtained through our
field test, grouping all images of yellow lichens together and grouping all
images of a coal bed together, and giving a 91% accuracy for similarity
detection. Such similarity detection could be employed to make maps of
different geological units. The novelty-detection performance of our system
was also rather good (a 64% accuracy). Such novelty detection may become
valuable in searching for new geological units, which could be of
astrobiological interest. By providing more advanced capabilities for
similarity detection and novelty detection, this image-compression technique
could be useful in giving more scientific autonomy to robotic planetary
rovers, and in assisting human astronauts in their geological exploration.
