  2. 21. A Knowledge-based System for Automatic Image Segmentation and Object Recognition

    Author : Sören Molander; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The present thesis describes a system for automatic off-line scene analysis of individual images and image sequences. The analysis is based on the use of a priori procedural knowledge of the task and declarative knowledge of the scene to be analyzed. READ MORE

  4. 22. A new kernel method for object recognition:spin glass-Markov random fields

    Author : Barbara Caputo; Stefan Arnborg; Kalle Åström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Datalogi; Computer science; Datalogi;

    Abstract : Recognizing objects through vision is an important part of our lives: we recognize people when we talk to them, we recognize our cup on the breakfast table, our car in a parking lot, and so on. While this task is performed with great accuracy and apparently little effort by humans, it is still unclear how this performance is achieved. READ MORE

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

    Author : Keren Fu; Chalmers tekniska högskola; []
    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

  6. 24. Semi-Autonomous Navigation of Powered Wheelchairs : 2D/3D Sensing and Positioning Methods

    Author : Cristian Vilar; Mattias O'Nils; Silvia Krug; Nicolas Ragot; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3D object recognition; YOLO; YOLO-Tiny; 3DHOG; Histogram-of-Oriented-Gradients; ModelNet40; Feature descriptor; Intel RealSense; Depth camera; Wheelchair;

    Abstract : Autonomous driving and assistance systems have become a reality for the automotive industry to improve driving safety in the car. Hence, the cars use a variety of sensors, cameras and image processing techniques to measure their surroundings and control their direction, braking and speed for obstacle avoidance or autonomously driving applications.

  7. 25. Anabolic Androgenic Steroids : Neurobiological Effects of Nandrolone, Testosterone, Trenbolone, and Stanozolol

    Author : Sofia Zelleroth; Mathias Hallberg; Astrid Bjørnebekk; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anabolic androgenic steroids; testosterone; nandrolone; trenbolone; stanozolol; central nervous system; primary cortical cell cultures; rats; multivariate concentric square field; novel object recognition.; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : The use of anabolic androgenic steroids (AAS) for recreational purposes is a health concern, as long-term AAS-use in supraphysiological doses is associated with severe physical and psychological adverse effects. Several behavioral and cognitive problems are reported after long-term AAS-use, and alterations in brain morphology as well as neurotransmitter systems have been reported. READ MORE
