This brings a new challenge of how to monitor and enforce social distancing when everyone is back on the roads.</div><div><br></div><div>CCTVs would be crucial in monitoring and enforcing social distancing in public places and in workplaces; The manual overhead in doing it is very high, fortunately if there's one thing which AI has proven itself as more capable than human beings it's computer vision.</div><div><br></div><div>But, since average CCTVs don't have depth perception, have different views and people are not in the same plane of axis; judging the distance between two people from video footage is a hard problem. Fortunately, Andrew Ng's company has released a tool to do just this and has released how the procedure works - <a href=""></a>.</div><div><br></div><div>It solves the problem of calculating distance by using homography to get top-down view of the image from video, using a manual calibration tool. Unfortunately, none of this has been open-sourced as of writing and hence a need gap for this to be released as an open-source tool for any govt. or workplace to make use of.</div><div><br></div><div>Such a tool can also be used on open CCTV feeds from Shodan, Insecam to analyse social distancing in countries around the world.</div> 3 points posted by Abishek Muthian /problems/111-automatic-monitoring-of-social-distance-via-cctv-artificialintelligence-socialdistancing 111 Fri, 17 Apr 2020 16:52:00 +0000 Democratisation of AI/ML/DL hardware #ArtificialIntelligence #Hardware Organisations like <a href="">OpenAI</a> are doing a commendable job in democratising Artificial Intelligence software stack i.e. opensource AI tools accessible to anyone and not just the big firms. But democratisation of hardware required for Machine Learning or Deep Learning is nowhere in sight.<div><br></div><div>GPU is already a big bottleneck for an individual/startup from a poor economic region. Considering, even entry level Software Engineering jobs now expect the candidates to know ML; it is imposing a huge disadvantage over a large sector of students from poor countries. AI accelerator hardware like TPU, Graphcore AI available to only big cloud companies would further worsen this.</div><div><br></div><div>This issue has largely to do with how semiconductor industry by itself is structured. With only handful of fabrication plants capable of mass producing semiconductors of this nature and they being integral part of 'soft power' in Geo-politics; it's hard for a startup to enter this space and when they do, they have no option to tie-up with these cloud companies.<br></div><div><br></div><div>Not only 'AI powered end product' will increase the inequality; but the ML education/research already has.</div> 3 points posted by Abishek Muthian /problems/50-dl-hardware-artificialintelligence-hardware 50 Mon, 18 Nov 2019 03:48:00 +0000
