1. 1. Time-based Key for Coverless Audio Steganography: A Proposed Behavioral Method to Increase Capacity

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : John Alanko Öberg; Carl Svensson; [2023]
   Keywords : Coverless audio steganography; information hiding; covert communication; effective capacity; behavioral; Täcklös ljudsteganografi; informationsdöljning; hemlig kommunikation; effektiv kapacitet; beteendemässig;

   Abstract : Background. Coverless steganography is a relatively unexplored area of steganography where the message is not embedded into a cover media. Instead the message is derived from one or several properties already existing in the carrier media. This renders steganalysis methods used for traditional steganography useless. READ MORE

3. 2. Performance Analysis of a Godot Game-Agnostic Streaming Tool

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Sam Axelsson; Filip Eriksson; [2023]
   Keywords : Streaming; Game-Agnostic; State Replication; Client Simulation; Godot Game Engine; Streaming; Spel-Agnostisk; State Replication; Client Simulation; Godot Spelmotor;

   Abstract : Background. Streaming games is traditionally done with video and audio both for watching on websites like Twitch and YouTube or playing via cloud gaming services. Streaming with video and audio requires good internet speeds to be of satisfactory quality therefore compression algorithms are used. READ MORE

4. 3. A Scalability and Performance Evaluation of Precomputed Flow FieldMaps for Multi-Agent Pathfinding

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Jonathan Helsing; Alexander Bruce; [2022]
   Keywords : pathfinding; flow field; multi-agent; precomputed; dijkstra maps;

   Abstract : Background. The A* algorithm is a well-established pathfinding technique frequently used in video game development. However, a disadvantage of the A* algorithm is that it becomes computationally inefficient and impractical to utilize whenthousands of agents demand an optimal path. READ MORE

5. 4. Comparison of Video Quality Assessment Methods

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Agata Jung; [2017]
   Keywords : Video Quality Assessment; Video Quality Prediction; Video Compression; Video Quality Metrics;

   Abstract : Context: The newest standard in video coding High Efficiency Video Coding (HEVC) should have an appropriate coder to fully use its potential. There are a lot of video quality assessment methods. These methods are necessary to establish the quality of the video. Objectives: This thesis is a comparison of video quality assessment methods.

6. 5. ON BITSTREAM FEATURES BASED PERCEPTUAL QUALITY ESTIMATION OF HEVC CODED VIDEOS

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Joanna Panasiuk; Lukasz Kowalczuk; [2015]
   Keywords : Artificial Neural Network; Video Coding Standard; Video Quality Assessment; Video Quality Prediction.; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

   Abstract : ABSTRACT Context: High Efficiency Video Coding (HEVC) is a new video coding standard which combines high video quality with higher compression ratios. In order to fully use the potential of this standard, there should be created an appropriate coding tool (coder), which determines proper coding parameters to ensure the highest possible video quality while maintaining a specified bitrate.
