  1. 1. Towards Joint Super-Resolution and High Dynamic Range Image Reconstruction

    Author : Tomas Bengtsson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Super-resolution; Dynamic range; Human visual system; Inverse problem; Image reconstruction; Spatial alignment; Photometric alignment; Digital camera system;

    Abstract : The main objective for digital image- and video camera systems is to reproduce a real-world scene in such a way that a high visual quality is obtained. A crucial aspect in this regard is, naturally, the quality of the hardware components of the camera device. There are, however, always some undesired limitations imposed by the sensor of the camera.

  3. 3. Methods for Processing and Analysis of Biomedical TEM Images

    Author : Amit Suveer; Ida-Maria Sintorn; Carolina Wählby; Natasa Sladoje; Jari Hyttinen; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image analysis; image processing; deep learning; transmission electron microscopy; denoising; super-resolution reconstruction; registration; detection; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Transmission Electron Microscopy (TEM) has the high resolving capability and high clinical significance; however, the current manual diagnostic procedure using TEM is complicated and time-consuming, requiring rarely available expertise for analyzing TEM images of the biological specimen. This thesis addresses the bottlenecks of TEM-based analysis by proposing image analysis methods to automate and improve critical time-consuming steps of currently manual diagnostic procedures.

  4. 4. 3D Human Pose and Shape Estimation Based on Parametric Model and Deep Learning

    Author : Zhongguo Li; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 3D Human body; Implicit function; Deep Learning; SMPL model; Parametric model; Pose and shape estimation;

    Abstract : 3D human body reconstruction from monocular images has wide applications in our life, such as movie, animation, Virtual/Augmented Reality, medical research and so on. Due to the high freedom of human body in real scene and the ambiguity of inferring 3D objects from 2D images, it is a challenging task to accurately recover 3D human body models from images.

  5. 5. Fluorescence Properties of Quantum Dots and Their Utilization in Bioimaging

    Author : Hao Xu; Ying Fu; Hjalmar Brismar; Marina Zelenina; Mattias Goksör; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Fluorescence; Microscopy; Bioimaging; Nanomaterial; cytotoxicity; mechanism; Biological Physics; Biologisk fysik;

    Abstract : Quantum dots (QDs), especially colloidal semiconductor QDs, possess properties including high quantum yields, narrow fluorescence spectra, broad absorption and excellent photostability, making them extremely powerful in bioimaging. In this thesis, we studied the fluorescence properties of QDs and attempted multiple ways to boost applications of QDs in bioimaging field. READ MORE
