I would like to do some reasearch job relating to automatic objects extraction along the road, like road markings, pole-like objects.

I have to pre-process the original data before applying my own algorithm, including segmentation of huge datasets, filtering of road poins, and feature image generation. What tools or opensource lib can I use?

I'm a freshman in this area and I'll appreciate it if you could give me any suggestions on this.

Good luck!
