  1. 1. Gaze-based JPEG compression with varying quality factors

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Henrik Nilsson; [2019]
    Nyckelord :Perception; Compression; Eye Tracking;

    Sammanfattning : Background: With the rise of streaming services such as cloud gaming, a fast internet speed is required for the overall experience. The average internet connection is not suited for the requirements that cloud gaming require. A high quality and frame rate is important for the experience. LÄS MER

  2. 2. HOW IMAGE DOWNSCALING AND JPEG COMPRESSION AFFECTS IMAGE CLASSIFICATION PERFORMANCE - An experimental study

    Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Alexander Hjältén; [2019]
    Nyckelord :;

    Sammanfattning : th‘e quality of an image plays a role in how well it can be correctly classi€fied by an image classifying neural network. Artifacts such as blur and noise reduces classi€filability. At the same time it is oft‰en motivated to reduce fi€le sizes of images which also tends to introduce artifacts and reduce their quality.

  3. 3. A study in how to inject steganographic data into videos in a sturdy and non-intrusive manner

    M1-uppsats, KTH/Hälsoinformatik och logistik; KTH/Hälsoinformatik och logistik

    Författare :Julius Andersson; David Engström; [2019]
    Nyckelord :Steganography; Steganalysis; Watermarking; Information hiding; Cryptography; Compression; Non-intrusive; Sturdy; JPEG; Steganografi; Steganalys; Vattenmärkning; Kryptografi; Kompression; Icke störande; Stabil; JPEG;

    Sammanfattning : It is desirable for companies to be able to hide data inside videos to be able to find the source of any unauthorised sharing of a video. The hidden data (the payload) should damage the original data (the cover) by an as small amount as possible while also making it hard to remove the payload without also severely damaging the cover.

  4. 4. 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. 5. Stable Communication Over a Wireless Network Under Heavy Load

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Mattias Eklund; Carl Nilsson Nyman; [2018]
    Nyckelord :wifi; lte; h.264; jpeg; 4g; Technology and Engineering;

    Sammanfattning : For our master's thesis we have worked with a company called Uniti to help them establish a system for communicating with their autonomous vehicle during a public demonstration. This included handling a video feed from the vehicle as well as assuring low latency for said feed. For the purposes of this thesis the targeted latency was below 200ms. LÄS MER
