  1. 16. High Dynamic Range Image Construction and Noise Reduction Using Differently Exposed Images

    University essay from Lunds universitet/Matematik LTH

    Author : Anton Öhrn; [2014]
    Keywords : HDR; HDR construction; Noise reduction; portable device imaging; image analysis; Mathematics and Statistics;

    Abstract : This thesis discuss how to use mutual information in differently exposed images to improve noise reduction. It also investigates how one can create an high dynamic range (HDR) image from multiple differently exposed images taken with a handheld camera while simultaneously cope with the problems this approach introduces.

  3. 17. Real-time image based lighting with streaming HDR-light probe sequences

    University essay from Medie- och Informationsteknik; Tekniska högskolan

    Author : Saghi Hajisharif; [2012]
    Keywords : ;

    Abstract : This work presents a framework for shading of virtual objects using high dynamic range (HDR) light probe sequences in real-time. The method is based on using HDR environment map of the scene which is captured in an on-line process by HDR video camera as light probes [32]. READ MORE

  4. 18. Real-time image based lighting with streaming HDR-light probe sequences

    University essay from Medie- och Informationsteknik; Tekniska högskolan

    Author : Saghi Hajisharif; [2012]
    Keywords : Picture Image Generation; Image based lighting; pre-computed radiance transfer; high dynamic range video;

    Abstract : This work presents a framework for shading of virtual objects using high dynamic range (HDR) light probe sequences in real-time. The method is based on using HDR environment map of the scene which is captured in an on-line process by HDR video camera as light probes. READ MORE

  5. 19. A Matlab Toolbox for fMRI Data Analysis: Detection, Estimation and Brain Connectivity

    University essay from Datorseende

    Author : Kiran Kumar Budde; [2012]
    Keywords : fMRI; functional Magnetic Resonance Imaging; Detection of activated regions; Estimation of hemodynamic response; Brain connectivity; Bayesian estimator; RBF; NARX; Granger causality.;

    Abstract : Functional Magnetic Resonance Imaging (fMRI) is one of the best techniques for neuroimaging and has revolutionized the way to understand the brain functions. It measures the changes in the blood oxygen level-dependent (BOLD) signal which is related to the neuronal activity. READ MORE

  6. 20. Hybrid Power Control in Time Division Scheduling Wideband Code Division Multiplex Access

    University essay from KTH/Kommunikationssystem, CoS

    Author : Zhuo Cheng; [2011]
    Keywords : WCDMA; High-Speed Uplink Packet Access; Power Control; unused code GRAKE;

    Abstract : With high date rates using Enhanced Uplink (EUL), a conventional signal to interference ratio (SIR) based power control algorithm may lead to a power rush due to self interference or incompatible SIR target [2]. Time division (TD) scheduling in Wideband Code Division Multiplex Access (WCDMA) is considered to be a key feature in achieving high user data rates. READ MORE
