1. 1. Content Based Video Encoding Based on Spatial and TemporalInformation

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Theofanis Papakonstantinou; [2023]
   Nyckelord :;

   Sammanfattning : A significant amount of video content is produced today that needs to be stored, distributed, andstreamed globally in a cost-effective way. This relies on video compression, a process performedby encoding software that remove spatial redundancy, the similarities within a frame, andtemporal redundancy, the similarities between temporarily adjacent frames.

3. 2. Exploiting Spatial Redundancy and Approximate Computing for Area Efficient Image Compression

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

   Författare :Saurav Arjun; [2022]
   Nyckelord :Image Compression; VLSI; Spatial redundancy; DCT; Compression; System Verilog; Technology and Engineering;

   Sammanfattning : Owing to the intensive computation involved in the Discrete Cosine Transform during image com- pression, the design of the efficient hardware architectures for fast computation of the transform has become imperative, especially for real-time applications. Although fast computation techniques have been able to minimise the hardware computation complexity to a certain limit, they could further extend the research to figure out the interesting approaches which can be implemented on applications where power, speed and area are crucial factors to determine the performance of the system.

4. 3. Spatially Coupled Codes in Turbo Equalization

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

   Författare :Mgeni Makambi Mashauri; [2019]
   Nyckelord :Turbo equalization; spatial coupling; waterfall versus error floor; codes on graphs; iterative receivers; LDPC codes in turbo equalization; Technology and Engineering;

   Sammanfattning : In this thesis we investigate the application of spatial coupling in turbo equalization. We show that with spatial coupling we can have a fresh perspective on the trade-off between performance in the waterfall and error floor region often encountered in the choice of codes for turbo equalization.

5. 4. Towards Integrating Crowdsourced and Official Traffic Data : A study on the integration of data from Waze in traffic management in Stockholm, Sweden

   Master-uppsats, Uppsala universitet/Informationssystem

   Författare :Isak Eriksson; [2019]
   Nyckelord :Traffic Management Systems; Swedish Transport Administration; Waze; Crowdsourcing; Data Integration;

   Sammanfattning : Modern traffic management systems often rely on static technologies, such as sensors and CCTV-cameras, in the gathering of data regarding the current traffic situation. Recent reports have shown that this method can result in a lack of coverage in Stockholm, Sweden. LÄS MER

7. 5. Comparison of multi-temporal and multispectral Sentinel-2 and Unmanned Aerial Vehicle imagery for crop type mapping

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Stephania Zabala Ramos; [2017]
   Nyckelord :classification; Random Forest; precision agriculture; UAV; remote sensing; Micasense; GEM; Earth and Environmental Sciences;

   Sammanfattning : Precision Agriculture aims to maximize crop production and the efficiency of land use to meet the increased demand for food while minimizing environmental impact and economic cost of food production. Crop type maps are needed for Precision Agriculture applications and remote sensing techniques are an efficient way to produce this information. LÄS MER
