  1. 11. Automatic Matching of Multimodular Images in Live Golf Environments : An Evaluation of Methods to Estimate a Homography Between Multimodular Images

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Ludvig Jansson; [2016]
    Keywords : image matching automatic golf detector descriptor computer vision homography;

    Abstract : This degree project evaluates combinations of well-known state-of-the-art keypoint detectors and descriptors, as well as keypoint matching and robust outlier rejection methods for the purpose of estimating a homography between images produced by two fundamentally different cameras. The evaluation is perfomed on both computational efficiency and matching accuracy of each combination after a series of image deformations have been applied. READ MORE

  3. 12. Stabilization, Sensor Fusion and Path Following for Autonomous Reversing of a Full-Scale Truck and Trailer System

    University essay from Linköpings universitet/Reglerteknik

    Author : Patrik Nyberg; [2016]
    Keywords : Truck; Reversing; Reversing trailer system; Reversing trailer; trailer; truck and trailer; control; LQ; linear quadratic control; sensor fusion; Kalman filter; EKF; KF; RANSAC; LiDAR; autonomous; driver aid;

    Abstract : This thesis investigates and implements the sensor fusion necessary to autonomously reverse a full size truck and trailer system. This is done using a LiDAR mounted on the rear of the truck along with a RTK-GPS. READ MORE

  4. 13. Needle Localization in Ultrasound Images : FULL NEEDLE AXIS AND TIP LOCALIZATION IN ULTRASOUND IMAGES USING GPS DATA AND IMAGE PROCESSING

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Kilian Demeulemeester; [2015]
    Keywords : ;

    Abstract : Many medical interventions involve ultrasound based imaging systems to safely localize and navigate instruments into the patient body. To facilitate visual tracking of the instruments, we investigate the techniques and methodologies best suited for solving the problem of needle localization in ultrasound images. READ MORE

  5. 14. Robust Time Difference Estimation for Unknown Microphone Positions with Reverberation

    University essay from Lunds universitet/Matematik LTH

    Author : Simon Segerblom Rex; [2015]
    Keywords : TDOA; RANSAC; GCC-PHAT; GCC; time difference; range difference; sound tracking; Technology and Engineering; Mathematics and Statistics;

    Abstract : In this thesis a system is developed for robust time difference estimation for multiple microphones in reverberant environments, without any knowledge of the 3D positions of the microphones or the room. RANSAC is used to find line segments in sets of frames containing a number of the largest GCC-PHAT peaks. READ MORE

  6. 15. Article identification for inventory list in a warehouse environment

    University essay from Högskolan i Halmstad/Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Yang Gao; [2014]
    Keywords : Object recognition; SIFT feature; Feature matching; DBSCAN; RANSAC; Bag of Words;

    Abstract : In this paper, an object recognition system has been developed that uses local image features. In the system, multiple classes of objects can be recognized in an image. This system is basically divided into two parts: object detection and object identification. READ MORE
