<div dir="ltr">Carl, that was a very helpful and thorough response.<div><br></div><div>We've been using a tool called ImagePlay. <a href="http://imageplay.io/">http://imageplay.io/</a> It's open source and based on OpenCV. The team used it to create a pipeline that has some potential to help navigation in this year's challenge. Since it's open source, once you have a pipeline, you can figure out the calls to it makes to opencv to construct the stages. It's based on the C++ implementation so the team has to translate that to java for their Android controllers. It has a very nice pipeline editor that supports branching. The downside is that it is very unstable and doesn't have anywhere near the number of filters and algorithms that RoboRealm supports.</div><div><br></div><div>We did ask RoboRealm for a license and they responded positively last week! It took them a while to verify that we were a FIRST robotics team - they support individual FIRST teams with licenses. It's much easier to experiment with and they have great documentation so now have an improved pipeline. It's going to take more work to figure out how to implement that pipeline in OpenCV. We can't use the RoboRealm capabilities directly. But as a tool for learning different aspects of computer vision, RoboRealm rocks. Thanks for your original presentation posted to the DPRG youtube channel - it helped us get up to speed quickly.</div><div><br></div><div>Peace,</div><div><br></div><div>Karim</div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Oct 5, 2017 at 7:36 AM, Carl Ott <span dir="ltr"><<a href="mailto:carl.ott.jr@gmail.com" target="_blank">carl.ott.jr@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Yes - <div><br></div><div>I noticed the dramatic change in RoboRealm price structure a couple months ago when I went to renew. $50 or a little per year is a good level - the steady stream of updates and community forum is well worth it. But commercial only licenses bumped to $500 - which is too high for my learning purposes. I found some indication in the forums that a pricing structure like this was tried some years back, so maybe educational pricing will return like it appeared to before. I really wish they'd offer price tiers based on support, where the educational price level remains available but perhaps with limited or no official support beyond other users in the community forum.</div><div>Anyhow, I've greatly appreciated the author, who has been very responsive and helpful with every request I've made.
