  1. 1. Similarity metric for crowd trajectory evaluation on a per-agent basis : An approach based on the sum of absolute differences

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Karl Brunnberg; [2023]
    Keywords : Crowd Simulation; Trajectory; Similarity Metric; Virtual Agents; Crowd Perception; Folkmassasimulering; Färdväg; Likhetsmetrik; Virtuella Agenter; Folkmassaperception;

    Abstract : Simulation models that replicate realistic crowd behaviours and dynamics are of great societal use in a variety of fields of research and entertainment. In order to evaluate the accuracy of such models there is a demand for metrics and evaluation solutions that measure how well they simulate the dynamics of real crowds. READ MORE

  3. 2. Retrofitting analogue meters with smart devices : A feasibility study of local OCR processes on an energy critical driven system

    University essay from

    Author : Joel Andreasson; Elin Ehrenbåge; [2023]
    Keywords : Analogue meters; Energy efficiency; Internet of Things IoT ; Optical Character Recognition OCR ; Sum of Absolute Differences SAD ; Template matching;

    Abstract : Internet of Things (IoT) are becoming increasingly popular replacements for their analogue counterparts. However, there is still demand to keep analogue equipment that is already installed, while also having automated monitoring of the equipment, such as analogue water meters. READ MORE

  4. 3. Video Quality Metric improvement using motion and spatial masking

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Henrik Näkne; [2016]
    Keywords : Video Quality Metrics; Optical Flow;

    Abstract : Objective video quality assessment is of great importance in video compression and other video processing applications. In today's encoders Peak Signal to Noise Ratio or Sum of Absolute Differences are often used, though these metrics have limited correlation to perceived quality. READ MORE

  5. 4. Hardware bidirectional real time motion estimator on a Xilinx Virtex II Pro FPGA

    University essay from Institutionen för systemteknik

    Author : Rashid Iqbal; [2006]
    Keywords : Bidirectional motion estimation; FPGA; Relationally placed macro; CLB; slice; tristate buffers; comparator; pipelining; search upper; search lower; VHDL; Xilinx; block matching; MeEngine; LMC; CMC.; sum of absolute differences; systolic array; SARow; PE2X8; MeProC; 125 MHz; Virtex II Pro;

    Abstract : This thesis describes the implementation of a real-time, full search, 16x16 bidirectional motion estimation at 24 frames per second with the record performance of 155 Gop/s (1538 ops/pixel) at a high clock rate of 125 MHz. The core of bidirectional motion estimation uses close to 100% FPGA resources with 7 Gbit/s bandwidth to external memory. READ MORE

  6. 5. EC Competition Policy on Compulsory Licensing of Intellectual Property Rights

    University essay from Lunds universitet/Juridiska institutionen

    Author : Anna Oscarsson; [2002]
    Keywords : Konkurrensrätt; EG-rätt; Immaterialrätt; Law and Political Science;

    Abstract : Both competition law and intellectual property law are considered good for economic efficiency, but the interface between the two legal fields is, and probably always will be, a complex area of law, since these legal areas in one sense can be said to strive for the opposite things. Intellectual property rights are considered public goods, which mean that it is hard to prevent others from using the goods without paying for it. READ MORE
