Generalized Architecture for a Real-time Computation of an Image Component Features on a FPGA
-
Other publication (other academic/artistic)abstract
- This paper describes a generalized architecture for real-time component labeling and computation of image component features. Computing real-time image component features is one of the most important paradigms for modern machine vision systems. Embedded machine vision systems demand robust performance, power efficiency as well as minimum area utilization. The presented architecture can easily be extended with additional modules for parallel computation of arbitrary image component features. Hardware modules for component labeling and feature calculation run in parallel. This modularization makes the architecture suitable for design automation. Our architecture is capable of processing 390 video frames per second of size 640x480 pixels. Dynamic power consumption is 24.20mW at 86 frames per second on a Xilinx Spartran6 FPGA.

Kapitel XIX. Typer och syndrom
- 2023
-
Other publication (other academic/artistic)abstract
- Kapitel XIX är ett av de avslutande kapitlen i The Authoritarian Personality. Här summerar Theodor W. Adorno de resultat som framkommit vid analysen av intervjuerna med de personer som fått högst respektive lägst poäng på den så kallade F-skalan och alltså uppvisar mest eller minst av de fördomar och auktoritära attityder som skalan mäter. De två grupperna av high scorers och low scorers grupperar Adorno sedan ytterligare i en typologi med ett större antal undergrupper. Grupperna definieras som psykologiska syndrom enligt den av freudiansk psykoanalys inspirerade teori som vägleder hela undersökningen. Gruppen med högst poäng delas upp i ytligt förbittrade, konventionella, auktoritära, rebeller eller psykopater, excentriker och manipulativa. Gruppen med lägst poäng delas upp i rigida, protesterande, impulsiva, lättsamma och genuina liberaler. Kapitlet inleds med en kritisk diskussion av typologibegreppet så som det användes vid tiden för studien i konventionell – och i nazistisk – psykologi, där Adorno redogör för sitt eget angreppssätt.Publiceringshistorik: Översättning av kapitel XIX, ”Types and syndromes”, i Theodor W.

The Plenoptic Dataset
- 2018
-
Other publicationabstract
- The dataset is captured using two different plenoptic cameras, namely Illum from Lytro (based on plenoptic 1.0 model) and R29 from Raytrix (based on plenoptic 2.0 model). The scenes selected for the dataset were captured under controlled conditions. The cameras were mounted onto a multi-camera rig that was mechanically controlled to move the cameras with millimeter precision. In this way, both cameras captured the scene from the same viewpoint.

Design of a Parallel A/D-converter System on PCB - For High-Speed Sampling and Timing Error Correction : Examensarbete - Linköpings universitet
- 2002
-
Other publication (other academic/artistic)abstract
- The goals for most of today´s receiver system are sampling at high-speed, with high resolution and with as few errors as possible. This master thesis describes the design of a high-speed sampling system with �state-of-the-art� components available on the market. The system is designed with a parallel Analog-to-digital converter (ADC) architecture, also called time interleaving. It aims to increase the sampling speed of the system. The system described in this report uses four 12-bits ADCs in parallel. Each ADC can sample at 125 MHz and the total sampling speed will then theoretically become 500 Ms/s. The system has been implemented and manufactured on a printed circuit board (PCB). Up to four boards can be connected in parallel to get 2 Gs/s theoretically. In an approach to increase the systems performance even further, a timing error estimation algorithm will be used on the sampled data. This algorithm estimates the timing errors that occur when sampling with non-uniform time interval between samples. After the estimations, the sampling clocks can be adjusted to correct the errors. This thesis is concerning some ADC theory, system design and PCB implementation. It also describes how to test and measure the system�s performance. No measurement results are presented in this thesis because measurements will be done after this project. The last part of the thesis discusses future improvements to achieve even higher performance.

Varför brinner skogen? Lokala svar på ett globalt problem
- 2022
-
Other publication (pop. science, debate, etc.)abstract
- Ett varmare och i vissa regioner torrare klimat ökar risken för omfattande skogsbränder som hotar mänsklig säkerhet. Men extrema väderhändelser leder inte nödvändigtvis till att klimatförändringarna får ökad uppmärksamhet. Vad som sätts i fokus avgörs istället av hur händelsen ramas in. Studier av de omfattande skogsbränderna i Sverige 2014 och 2018 visar att orsakerna gärna definieras inom ramen för vad man lokalt kan påverka.
