last year I made a resolution to do daily code sketches for fun: https://www.instagram.com/zach.lieberman/ I have learned a great deal from the act of daily coding and treating cod…

thanks!

I just saw this thread... I wrote this article (and made the sketches here: https://www.instagram.com/zach.lieberman/ ) -- happy to answer any questions! also if it's helpful to an…

I'll take a look - thanks! note that we do limit the line somewhat since the best matches are curves, lines, etc and self intersecting lines don't match very well.. The best kinds …

sorry! this is a bug based on how many events the mouse is firing and I've open an issue for it -- I will take a look at the app with a gaming mouse and work on a fix.

thanks -- do you know what graphics card that is? also you can try enabling "Override software rendering list" in chrome://flags/ -- I don't have a great handle on what gpus are bl…

I'm not on the data arts team (I collaborated with them on this) but I'll ping them to answer. This was a passion project, they approached me with a set of data -- satellite images…

fixed! thanks!

thanks! I am using a metric from the dollar gesture recognizer http://depts.washington.edu/madlab/proj/dollar/index.html which gives a value for how close to polylines are (it norm…

I think that's a great idea... I will take a look at that. here's a hack in the meantime someone put together for doing that: https://gist.github.com/spite/90e3dbf8e117660f6788a574…

no it's a really good question! I think this just has to do with the line detection algorithm and it tending to find more curves than sharp angle lines -- this is what the matches …

the matching is based on the input (lines from the line detection) and we do some tricks to try to get better matches if the results aren't great. One trick is for matches that are…

there's actually no backend! the matching is done client side. here's a technical write up: https://developers.google.com/web/showcase/2016/land-lines the trick for making it fast …

sorry to hear that! can you provide more info about your platform? this app uses webgl and we check for webgl support when the page loads.

this is a write up of a year of doing code based sketches -- last year I started to do a sketch per day here: https://www.instagram.com/zach.lieberman/ I am happy to answer any que…

also another tip -- you can click on the city name in the left corner to load the same view in google earth (if you are curious about what you are looking at!)

thanks! that's great to hear

the line is limited to a certain lengths since simpler lines (curves, etc) provide better matches

also if it's helpful, there's a technical write up here: https://medium.com/@zachlieberman/land-lines-e1f88c745847#.k... and overview video: https://www.youtube.com/watch?v=w6-LK9B…

I helped make this (with the google data arts team), happy to answer any questions about it.

thanks! -- I didn't know the history. these notes are from 2008 (long after opencv was open sourced) but it's clear from his linkedin page that he was a part of the founding team a…

He wrote the Learning OpenCV book but I'm not sure it's accurate to say he created openCV... It was created by intel internally (by a ton of folks like Vadim Pisarevsky) and later …
