  1. 1. Object Classification and Image Labeling using RGB-Depth Information

    Författare :Mostafa Pordel; Thomas Hellström; Ulrik Söderström; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis is part of research for the vision systems of four robots in the EU funded project, CROPS[l], where the robots should harvest apples, sweet peppers and grapes, and explore forests. The whole process of designing such a system, including the software architecture, creation of the image database, image labeling and object detection, is presented. LÄS MER

  3. 2. Controlling the Fluorescence Properties of Diarylethene-based Photochromic Systems

    Författare :Gaowa Naren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; isomerization; color change; photochromic molecules; molecular logic; intensity modulation; diarylethene; RGB; all-photonic; FRET;

    Sammanfattning : Diarylethene (DAE) photoswitches are one of the most promising families of photochromic molecules because of their outstanding photophysical/photochemical properties. This class of compounds, which can photoisomerize between an open colorless and a closed colored form, has been applied in various fields in this thesis work, spanning one-color fluorescence intensity modulation, all-photonic full-color reproduction, light-induced color changes for molecular logic gates and information processing.

  4. 3. Unsupervised construction of 4D semantic maps in a long-term autonomy scenario

    Författare :Rares Ambrus; Patric Jensfelt; John Folkesson; Andreas Nüchter; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mobile robotics; autonomous systems; perception; computer vision; RGB-D object segmentation; modelling and recognition; semantic segmentation; long-term autonomy; mapping; temporal modeling; Computer Science; Datalogi;

    Sammanfattning : Robots are operating for longer times and collecting much more data than just a few years ago. In this setting we are interested in exploring ways of modeling the environment, segmenting out areas of interest and keeping track of the segmentations over time, with the purpose of building 4D models (i.e. LÄS MER

  5. 4. Vision-based Perception For Autonomous Robotic Manipulation

    Författare :Dinh-Cuong Hoang; Todor Stoyanov; Achim Lilienthal; Per-Erik Forssén; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In order to safely and effectively operate in real-world unstructured environments where a priori knowledge of the surroundings is not available, robots must have adequate perceptual capabilities. This thesis is concerned with several important aspects of vision-based perception for autonomous robotic manipulation. LÄS MER

  7. 5. Colour Correction of Underwater Images Using Spectral Data

    Författare :Julia Åhlén; Ewert Bengtsson; Jussi Parkkinen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; Colour; Correction; Attenuation; Coefficient; Underwater; Bildanalys; Image analysis; Bildanalys; Computer science;

    Sammanfattning : For marine sciences sometimes there is a need to perform underwater photography. Optical properties of light cause severe quality problems for underwater photography. Light of different energies is absorbed at highly different rates under water causing significant bluishness of the images. LÄS MER
