    Abstract : This thesis examines compression algorithms for time series operational data which are collected from the Controller Area Network (CAN) bus in an automotive Internet of Things (IoT) setting. The purpose of a compression algorithm is to decrease the size of a set of time series data (such as vehicle speed, wheel speed, etc. READ MORE

  6. 20. Hardware Efficient Lossless Realtime Compression of Raw Image Data

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Måns Åhlander; Axel Jonsson; [2018]
    Keywords : Compression; Realtime; Video; Encoding; Bitrate; Technology and Engineering;

    Abstract : When transmitting data it is often desired to lower the bitrate in the transmission. In video capture devices, such as video cameras, with a high resolution and high capturing rate the bitrate in the transmission is high and it is often desired to lower this bitrate. READ MORE
