  1. 1. Deep Learning based Video Super- Resolution in Computer Generated Graphics

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Vinit Jain; [2020]
    Nyckelord :Deep Learning; Convolutional Neural Networks; Video Super-Resolution; Computer Generated Graphics; Gaming.; Deep Learning; Convolutional Neural Networks; Video Super-Resolution; Computer Generated Graphics; Gaming.;

    Sammanfattning : Super-Resolution is a widely studied problem in the field of computer vision, where the purpose is to increase the resolution of, or super-resolve, image data. In Video Super-Resolution, maintaining temporal coherence for consecutive video frames requires fusing information from multiple frames to super-resolve one frame. LÄS MER

  3. 2. Evaluating the Impact of V-Ray Rendering Engine Settings on Perceived Visual Quality and Render Time : A Perceptual Study

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Andreas Linné; [2019]
    Nyckelord :V-Ray; Computer-Generated Imagery; Rendering; Perception; Subjective Evaluation;

    Sammanfattning : Background. In computer graphics, it can be a time-consuming process to render photorealistic images. This rendering process, called “physically based rendering” uses complex algorithms to calculate the behavior of light. LÄS MER

  4. 3. Objective Perceptual Quality Assessment of JPEG2000 Image Coding Format Over Wireless Channel

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Bala Venkata Sai Sundeep Chintala; [2019]
    Nyckelord :Discrete Wavelet Transform DWT ; Image Coding Format; JPEG2000; Objective Perceptual Quality assessment; Quality of Experience QoE ;

    Sammanfattning : A dominant source of Internet traffic, today, is constituted of compressed images. In modern multimedia communications, image compression plays an important role. Some of the image compression standards set by the Joint Photographic Expert Group (JPEG) include JPEG and JPEG2000. LÄS MER

  5. 4. DEVELOPMENT OF AN ROI AWARE FULL-REFERENCE OBJECTIVE PERCEPTUAL QUALITY METRIC ON IMAGES OVER FADING CHANNEL

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :SRI LOHITH GOGINENI; [2016]
    Nyckelord :Visual Information Fidelity; Quality of Experience; Image; Full-Reference; Objective Perceptual Metrics; Region-of-Interest;

    Sammanfattning : In spite of technological advances in wireless systems, transmitted data suffers from impairments through both lossy source coding and transmission overerror prone channels. Due to these errors, the quality of multimedia content is degraded. LÄS MER

  7. 5. Creation & Assessment of a Video Quality Ruler

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Maya Shah; [2016]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Image quality has always been a matter of great importance for anyone working with or consuming images and videos. Images and videos are, in general, for human consumption. Thus, image quality is essentially a subjective attribute of an image. LÄS MER
