Parallel Implementation of Dianthus XStream Forwarding Optimization
We have now parallel implemented our Forwarding Optimization, making it more than twice as fast. On a typical logging tract, we have now reduced the computation time to 20 seconds. Our XStream Forwarding Optimization is accessible from our Skogskartor REST API and can directly contribute to reducing driving damage in the terrain, as well as enabling you to immediately obtain very accurate values for the current terrain transport work.
Our Forwarding Optimization is inspired by Skogforsk's Bestway but has been developed from the ground up by us at Dianthus in collaboration with SCA. Professor Emerita at Uppsala University, Gunilla Borgefors, laid the foundation for our computation core through her ingenious digital distance transform. As one of Borgefors' first PhD graduates at the Centre for Image Analysis (SLU), Fredrik Walter has, since Dianthus' founding nearly 25 years ago, frequently applied and further developed Borgefors' distance transform.
"We use Borgefors' distance transform in all our services and products. We use it to calculate distances, find the nearest path—weighted and with restrictions, measure widths, thin and grow objects and regions, and much more. It is somewhat of our Swiss Army knife, which in its simplicity is very ingenious and very computationally fast."
Borgefors' distance transform has thus, behind the scenes, provided significant benefits to Swedish forestry for over 25 years.
Gunilla Borgefors holds a Doctor of Technology degree and worked at the Swedish Defence Research Agency in Linköping from 1982-1993. There, Borgefors became the research director for computer vision and head of the information systems division. In 1993, she transitioned to a professorship at the Swedish University of Agricultural Sciences, where she led the Center for Image Analysis in Uppsala. In 2005, she began a guest professorship at Uppsala University and, in 2012, transitioned to a full-time professorship there.
