1. 1. Perception of variety in forests in relation to reducing polygon count : Exploring human perception in computer graphics and computer graphics education

   Uppsats för yrkesexamina på avancerad nivå, KTH/Lärande

   Författare :Amani Najimudeen; [2023]
   Nyckelord :aggregates; perception; forests; computer graphics education; aggregat; mänsklig uppfattning; skogar; datorgrafikundervisning;

   Sammanfattning : By taking human perception into account in computer graphics, time and processing power may be utilised more efficiently when modelling and rendering scenes. Exploring possibilities for reducing the complexity of forest scenes is particularly interesting because of the geometric complexity of trees, the effects of which are compounded by dense, large-scale forests.

   Sammanfattning : In recent years, texture synthesis has been a heated topic in computer graphics, and the development of advanced algorithms for generating high-quality 3D textures is an area of active research. A recently proposed model, Neural Cellular Automata, can synthesize realistic 2D texture images or videos. LÄS MER

4. 3. A Performance Comparison of Path Tracing on FPGA and GPU

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

   Författare :Anton Lilja; Markus Videfors; [2023]
   Nyckelord :;

   Sammanfattning : Ray Tracing algorithms have long been the popular choice for rendering realistic images, and in recent years they have also reached the field of real time computer graphics. Although their performance has seen great improvement, they are still very computationally costly to perform, both in terms of time and power. LÄS MER

5. 4. Applying spatially and temporally adaptive techniques for faster DEM-based snow simulation

   Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Författare :Simon Andreasson; Linus Östergaard; [2023]
   Nyckelord :Real-time simulation; DEM; GPU; Games; Computer graphics; Realtidssimulering; DEM; GPU; Spel; Datorgrafik;

   Sammanfattning : Background. Physically-based snow simulation is computationally expensive and not yet applicable to real-time applications. Some of the prime factors for this cost are the complex physics, the large number of particles, and the small time step required for a high-quality and stable simulation. LÄS MER

7. 5. Video Retargeting using Vision Transformers : Utilizing deep learning for video aspect ratio change

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

   Författare :Gil Laufer; [2022]
   Nyckelord :Video retargeting; Aspect ratio; Computer vision; Deep learning; Vision transformers.; Video retargeting; Bildförhållande; Datorseende; Djupinlärning; Vision transformers.;

   Sammanfattning : The diversity of video material, where a video is shot and produced using a single aspect ratio, and the variety of devices that can play video with screens in different aspect ratios make video retargeting a relevant topic. The process of fitting a video filmed in one aspect ratio to a screen in another aspect ratio is called video retargeting, and the retargeted video should ideally preserve the important content and structure of the original video as well as be free of visual artifacts.
