   Författare :Sebastian Hjelm; Mattias Gustafsson; [2018]
   Nyckelord :Machine learning; Neural networks; Vehicle detection; CNN; Metadata; Bitrate; QP; Fast; Privacy; Technology and Engineering;

   Sammanfattning : The current field of object detection and image recognition is huge but not without complications. Processing large amounts of high resolution videos needs powerful hardware and also risks breaching the privacy of those who are recorded. LÄS MER

4. 23. HTTP Based Adaptive Bitrate Streaming Protocols in Live Surveillance Systems

   Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Daniel Dzabic; Mårtensson Jacob; [2018]
   Nyckelord :HLS; DASH; Adaptive Bitrate Streaming; Video Streaming; RTMP; nginx;

   Sammanfattning : This thesis explores possible solutions to replace Adobe Flash Player by using toolsalready built into modern web browsers, and explores the tradeoffs between bitrate, qual-ity, and delay when using an adaptive bitrate for live streamed video. Using an adaptivebitrate for streamed video was found to reduce stalls in playback for the client by adapt-ing to the available bandwidth. LÄS MER
