  1. 1. Urban Change Detection Using Multitemporal SAR Images

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Osama Yousif; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Change detection; High resolution; Image denoising; Kittler-Illingworth; MAP-MRF; Multitemporal SAR images; Nonlocal means; Object-based; Otsu; Outlier detection; Remote sensing; SAR speckle; Urban; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Sammanfattning : Multitemporal SAR images have been increasingly used for the detection of different types of environmental changes. The detection of urban changes using SAR images is complicated due to the complex mixture of the urban environment and the special characteristics of SAR images, for example, the existence of speckle.

  2. 2. Ground Object Recognition using Laser Radar Data Geometric Fitting, Performance Analysis, and Applications

    Detta är en avhandling från Institutionen för systemteknik

    Författare :Christna Grönwall; Linköpings universitet.; Linköpings universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser radar; object detection; object recognition; performance; least squares; ICP; Cramér-Rao; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling;

    Sammanfattning : This thesis concerns detection and recognition of ground object using data from laser radar systems. Typical ground objects are vehicles and land mines. For these objects, the orientation and articulation are unknown. The objects are placed in natural or urban areas where the background is unstructured and complex. LÄS MER

  3. 3. Change Detection of the Unexpected : Enhancing change detection of the unexpected in a complex and high risk context – guiding visual attention in a digital display environment

    Detta är en avhandling från Uppsala : Institutionen för informatik och media

    Författare :Ulrik Spak; Uppsala universitet.; Försvarshögskolan.; [2015]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Människa-dator interaktion; Human-Computer Interaction; awareness; change blindness; change detection; command and control; display; feedback; human-computer interaction; inattentional blindness; monitoring; surveillance; visual cue; Ledningsvetenskap; Ledningsvetenskap;

    Sammanfattning : Change detection of objects and events in our visual surroundings is sometimes severely difficult, especially if these changes are unexpected. Such failures in change detection may cause huge malicious outcomes in contexts characterized by high levels of complexity and risk. LÄS MER

  4. 4. Detection and Tracking in Thermal Infrared Imagery

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Amanda Berg; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermal; infrared; detection; tracking;

    Sammanfattning : Thermal cameras have historically been of interest mainly for military applications. Increasing image quality and resolution combined with decreasing price and size during recent years have, however, opened up new application areas. They are now widely used for civilian applications, e.g. LÄS MER

  5. 5. Safe Robotic Manipulation to Extract Objects from Piles From 3D Perception to Object Selection

    Detta är en avhandling från Örebro : Örebro university

    Författare :Rasoul Mojtahedzadeh; Örebro universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Object Selection; Object Pose Refinement; Gravitational Support Relation; Inter-penetration Resolving; 3D Ranging Sensor Evaluation; Datavetenskap; Computer Science;

    Sammanfattning : This thesis is concerned with the task of autonomous selection of objects to remove (unload) them from a pile in robotic manipulation systems. Applications such as the automation of logistics processes and service robots require an ability to autonomously manipulate objects in the environment. LÄS MER
