  2. 1. Urban Change Detection Using Multitemporal SAR Images

    Author : Osama Yousif; Yifang Ban; Lorenzo Bruzzone; KTH; []
    Keywords : 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;

    Abstract : 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.

  4. 2. Shape-based Representations and Boosting for Visual Object Class Detection : Models and methods for representaion and detection in single and multiple views

    Author : Oscar Danielsson; Stefan Carlsson; Josephine Sullivan; Bernt Schiele; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Detection of generic visual object classes (i.e. cars, dogs, mugs or people) in images is a task that humans are able to solve with remarkable ease. Unfortunately this has proven a very challenging task for computer vision. READ MORE

  5. 3. Detection and Tracking in Thermal Infrared Imagery

    Author : Amanda Berg; Michael Felsberg; Jörgen Ahlberg; Thomas B. Moeslund; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermal; infrared; detection; tracking;

    Abstract : 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. READ MORE

  6. 4. Safe Robotic Manipulation to Extract Objects from Piles : From 3D Perception to Object Selection

    Author : Rasoul Mojtahedzadeh; Achim J. Lilienthal; Todor Stoyanov; Abdelbaki Bouguerra; Erik Schaffernicht; Patric Jensfelt; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Object Selection; Object Pose Refinement; Gravitational Support Relation; Inter-penetration Resolving; 3D Ranging Sensor Evaluation; Computer Science; Datavetenskap;

    Abstract : 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. READ MORE

  7. 5. Cost Optimization of Volumetric Surveillance for Sky Monitoring : Towards Flying Object Detection and Positioning

    Author : Hiba Alqaysi; Mattias O'Nils; Najeem Lawal; Faisal Qureshi; Fabio Poiesi; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; image processing; deep learning; YOLOv4; smart cameras;

    Abstract : Unlike surface surveillance, volumetric monitoring deals with three-dimensional target space and moving objects within it. In sky monitoring, objects fly within outdoor and often remote volumes, such as wind farms and airport runways. Therefore, multiple cameras should be implemented to monitor these volumes and analyze flying activities. READ MORE
