Subject: Re: [ros-users] Detecting Glass Walls
Yeah, plus they heavily depend on how the light reflects, angles, etc. Reflections are evil ;) I haven't seen too much
work on actually getting stereo from that. Is there any work on artificially generating reflections by manipulating
light (a PR2 with a flashlight moving around would be cool :) )?

Cheers,
Radu.
