  1. 1. Salient Region Detection Methods with Application to Traffic Sign Recognition from Street View Images

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Keren Fu; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; normalized cut; traffic sign recognition; saliency propagation; color distribution; continuous conditional random field; manifold; Salient region detection; adaptive graph edge weights; color contrast; geodesics;

    Abstract : In the computer vision community, saliency detection refers to modeling the selective mechanism in human visual attentions. Outputs of saliency detection algorithms are called saliency maps, which represent conspicuousness levels of different scene areas. READ MORE

  2. 2. Signaling for color change in melanophores and a biosensor application

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Annika M. Karlsson; Linköpings universitet.; Linköpings universitet.; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; color change; melanophores; tyrosine; phosphorylations; melatonin; nitric oxide; MEDICINE; MEDICIN;

    Abstract : Melanophores are dark brown pigment cells located in the skin of fish, amphibia, reptiles, and many invertebrates. The color of the animal can change via rearrangement of pigment granules, melanosomes, in the cells. The dark melanophores can either hide colorful cells so that the animal appears dark, or let through colors from underneath. READ MORE

  3. 3. Efficient Image Retrieval with Statistical Color Descriptors

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Linh Viet Tran; Linköpings universitet.; Linköpings universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; color properties; images; statistical; content-based image retrieval CBIR ; non-parametric density estimators; image database; Kernel; Gram-Schmidt; geometry-based; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science Information technology; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap Informationsteknologi;

    Abstract : Color has been widely used in content-based image retrieval (CBIR) applications. In such applications the color properties of an image are usually characterized by the probability distribution of the colors in the image. READ MORE

  4. 4. Depth Map Upscaling for Three-Dimensional Television The Edge-Weighted Optimization Concept

    University dissertation from Sundsvall, Sweden : Mittuniversitetet

    Author : Sebastian Schwarz; Mittuniversitetet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3d video; 3DTV; video coding; capture; distribution; EWOC; depth map upscaling; time-of-flight;

    Abstract : With the recent comeback of three-dimensional (3D) movies to the cinemas, there have been increasing efforts to spread the commercial success of 3D to new markets. The possibility of a 3D experience at home, such as three-dimensional television (3DTV), has generated a great deal of interest within the research and standardization community. READ MORE
