  1. 1. Evaluation of whole-body bone scans performed using a gamma camera with Cadmium Zinc Telluride detector

    University essay from

    Author : Victor Asp; [2022-01-13]
    Keywords : Medical physics; whole-body bone scans; gamma camera; Cadmium Zinc Telluride detector;

    Abstract : The bone scan is a common nuclear medicine imaging procedure that is mainly used for evaluating several oncological patient groups. A radioactive tracer, 99mTc -labelled diphosphonate, is injected intravenously and accumulates in the skeleton. The distribution of the tracer in the body is measured with a gamma camera 3 hours post-injection. READ MORE

  2. 2. Exploiting Spatial Redundancy and Approximate Computing for Area Efficient Image Compression

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

    Author : Saurav Arjun; [2022]
    Keywords : Image Compression; VLSI; Spatial redundancy; DCT; Compression; System Verilog; Technology and Engineering;

    Abstract : Owing to the intensive computation involved in the Discrete Cosine Transform during image com- pression, the design of the efficient hardware architectures for fast computation of the transform has become imperative, especially for real-time applications. Although fast computation techniques have been able to minimise the hardware computation complexity to a certain limit, they could further extend the research to figure out the interesting approaches which can be implemented on applications where power, speed and area are crucial factors to determine the performance of the system.

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Nsioh Elvis Nkioh; [2022]
    Keywords : geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

    Abstract :      One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. READ MORE

  4. 4. Machine Vision for Quality Inspection of Rear Axle Bridges

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Rickard Frykgård; [2022]
    Keywords : Machine vision; Machine learning; Quality inspection; Rear axle bridges; Amazon Rekognition; MVTec Halcon; Dot peen markings;

    Abstract : Dot peen markings are used by Scania Ferruform to maintain a traceability of their products throughout the manufacturing. Quality inspection of the markings are performed to ensure that they are added correctly and readable. This is, however, done manually by workers, which they are looking to change. READ MORE

  5. 5. Facial recognition techniques comparison for in-field applications : Database setup and environmental influence of the access control

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

    Author : Gustav Norvik; [2022]
    Keywords : facial recognition; deep learning; machine learning; computer vision; image processing; artificial intelligence;

    Abstract : A currently ongoing project at Stanley Security is to develop a facial recognition system as access control system to prevent theft of heavy vehicles for terrorist purposes. As of today, there are several providers of facial recognition techniques and the spectrum ranges from multi dollar licenses to easy access open source. READ MORE
