[{"_id":"project:233","_type":"project","abstract":{"en":"In this project we will construct different looking tags for various purposes including to mark physical locations, e.g. on skirting boards along the bottom of the walls discretely,  such that  all tags can be produced, identified as well as located efficiently and reliably by help of  joint image synthesis and analysis techniques. The aim is to enable  intelligent service robots in factories, hospitals, as well as in homes of  senior citizens, so that  they can  navigate reliably   to contribute to a more efficient functioning of  the society, sooner than later. The project will, by mathematical methods, optimize orientations of  visual curves that can survive harsh environmental conditions, from object to camera and then will  optimize  methods for error-free readings resulting in automatic decisions,  for example, to emit the choice of  control instructions moving a robot.  Simply stated, it amounts  to make a visual alphabet that offers two functions simultaneously: location and identity of symbols, and to provide for optimal methods to locate and decode the symbols of the alphabet by cameras. The project will primarily study to  embed the payload (location and identity) in  angle transitions  of  curves rather than their contrast, an idea that is inspired by FM radio (phase modulation) and that has revolutionized radio communication, which used amplitude modulation (AM) before."},"project_id":"2011-05819_VR","identifier_short":"2011-05819","dates":{"start_date":"2011-01-01","end_date":"2013-12-31"},"organizations":[{"funding":[{"_id":2,"id":"202100-5208","sv":"Vetenskapsrådet","en":"Swedish Research Council"}]},{"coordinating":[{"_id":2804,"id":"202100-3203","sv":"Högskolan i Halmstad","en":"Halmstad University"}]}],"people":[{"project_leaders":[{"_id":"authority-person:49705","orcid":"0000-0002-4929-1262","name":"Bigun, Josef","role":"principal_investigator","affiliation":[{"_id":13650,"sv":"CAISR Centrum för tillämpade intelligenta system (IS-lab)","en":"CAISR - Center for Applied Intelligent Systems Research","parent":[{"_id":3938,"sv":"Halmstad Embedded and Intelligent Systems Research (EIS)","en":"Halmstad Embedded and Intelligent Systems Research (EIS)","parent":[{"_id":16904,"sv":"Akademin för informationsteknologi","en":"School of Information Technology","parent":[{"_id":2804,"sv":"Högskolan i Halmstad","en":"Halmstad University"}]}]}]}]}]},{"other_personnel":[]}],"tags":[{"_id":11516,"id":"10207","sv":"Datorseende och robotik (autonoma system)","en":"Computer Vision and Robotics (Autonomous Systems)"},{"_id":11578,"id":"20201","sv":"Robotteknik och automation","en":"Robotics"},{"_id":11582,"id":"20205","sv":"Signalbehandling","en":"Signal Processing"}],"titles":{"sv":"Skala, orientering och belysning invariant kodning och avkodning -- En studie om invarianta visuella koder","en":"Scale, orientation and illumination invariant information encoding and  decoding-- A study on invariant visual codes"},"total_funding":"2460000","type_of_awards":{"sv":"Projektbidrag","en":"Project grant"},"publications":[],"links":[{"type":"pid","link":"https://hh.diva-portal.org/smash/api/project/swecris/project:233"}]}]
