A novel method of road centerline extraction based on image space clustering using PSO

What is it about?

Nowadays, automatic road centerline vectorization for road database updating is considered a challenging issue. in this paper an automatic road vectorization method based on PSO clustering of road pixels in the image space is proposed.

Why is it important?

Automatic road extraction plays an important role in road map updating prcedure. Extracting them automatically is much more time and cost efficient and decrease dependency on human operators.
