  1. 1. Objective measurement of video quality

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Hugo Granström; [2023]
    Keywords : image analysis; video analysis; sharpness; colorfulness; contrast; aesthetics; video stabilization; video stability; bildanalys; videoanalys; skärpa; färgladhet; kontrast; estetiskhet; videostabilisering;

    Abstract : Automatic video quality assessment has many potential use cases in today’s video-filledsociety, for example, when trying to find highlights in a video. This thesis studies the possibilityof extracting the best segments from a video automatically based on five selected metrics:sharpness, colorfulness, contrast, stability, and aesthetics. READ MORE

  3. 2. Quality Assessment for Halftone Images

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Johnny Elmèr; [2023]
    Keywords : Image Quality; Halftoning; Subjective Image Quality Assessment; Subjective Testing; Objective Image Quality Metrics;

    Abstract : Halftones are reproductions of images created through the process of halftoning. The goal of halftones is to create a replica of an image which, at a distance, looks nearly identical to the original. Several different methods for producing these halftones are available, three of which are error diffusion, DBS and IMCDP. READ MORE

  4. 3. Fingerprint Synthesis Using Deep Generative Models

    University essay from Lunds universitet/Matematik LTH

    Keywords : Fingerprint Synthesis; Deep Generative Models; Style Transfer; Metrics; Technology and Engineering;

    Abstract : The advancements in biometric technology have amplified the need for more robust fingerprint synthesis techniques. In this thesis, we first explored the application of synthesizing normal fingerprint images in high fidelity using deep generative models (e.g. READ MORE

  5. 4. Evaluation of Convolutional Neural Networks for Image Quality Classification based on Synthetic Data

    University essay from Lunds universitet/Matematik LTH

    Author : Vendela Nigård; Joar Karlgren Gustavsson; [2022]
    Keywords : Convolutional neural networks; Machine learning; transfer learning; image quality assessment; camera production; image analysis; Mathematics and Statistics;

    Abstract : In camera production the image quality is of utter importance. Several tests during the production ensure this high quality. In this thesis the possibility of creating a final test, that classifies the image quality with the help of machine learning, specifically convolutional neural networks, was investigated. READ MORE

  6. 5. Evaluation of Methods for Image Analysis with the Purpose of Imitating Subjective Quality Assessment

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Felix Grönborg; Otto Ortega; [2021]
    Keywords : ;

    Abstract : Detta examensarbete gjordes i samarbete med Husfoto AB där syftet var att undersöka potentialen i att använda maskininlärniningsalgoritmer för att utföra automatiska klassificeringar mellan godkända och icke-godkända bilder enligt en subjektivt framställd kvalitetsstandard. Både metoder som använder maskininlärning, samt mer traditionella bildanalysmetoder användes, testades och jämfördes inom kvalitetsmåtten precision, känslighet, träffsäkerhet och balanserad träffsäkerhet.
