  1. 11. Unsupervised Learning for Structure from Motion

    University essay from Linköpings universitet/Datorseende

    Author : Erik Örjehag; [2021]
    Keywords : sfm; structure from motion; depth; ego-motion; unsupervised learning; consensus maximization;

    Abstract : Perception of depth, ego-motion and robust keypoints is critical for SLAM andstructure from motion applications. Neural networks have achieved great perfor-mance in perception tasks in recent years. But collecting labeled data for super-vised training is labor intensive and costly. READ MORE

  3. 12. Local Feature Correspondence on Side-Scan Sonar Seafloor Images

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Li Ling; [2021]
    Keywords : ;

    Abstract : In underwater environments, the perception and navigation systems are heavily dependent on the acoustic wave based sonar technology. Side-scan sonar (SSS) provides high-resolution, photo-realistic images of the seafloor at a relatively cheap price. READ MORE

  4. 13. Digitizing notes using a moving smartphone : Evaluating Oriented FAST and Rotated BRIEF (ORB)

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Johan Wieslander; [2021]
    Keywords : Augmented reality; Computer vision; Mobile applications; Object detection; Feature extraction; Human computer interaction; Augmented reality; Förstärkt verklighet; Datorseende; Mobila applikationer; Objectdetektion; Människa-datorinteraktion;

    Abstract : This thesis investigates the problem of tracking objects for an Augmented Reality (AR) setting. More specifically, the issue of tracking Post-It® notes to be used in a Mobile Augmented Reality (MAR) application using the Oriented FAST and Rotated BRIEF (ORB) keypoint extractor and descriptor, is investigated.

  5. 14. Cascade Mask R-CNN and Keypoint Detection used in Floorplan Parsing

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Anton Eklund; [2020]
    Keywords : mask r-cnn; cascade r-cnn; cascade mask r-cnn; floorplan; floorplans; computer vision; CNN; convolutional neural networks;

    Abstract : Parsing floorplans have been a problem in automatic document analysis for long and have up until recent years been approached with algorithmic methods. With the rise of convolutional neural networks (CNN), this problem too has seen an upswing in performance. READ MORE

  6. 15. MobilePose: Real-Time 3D Hand Pose Estimation from a Single RGB Image

    University essay from Lunds universitet/Matematik LTH

    Author : David Larsson; Sofie Hellmark; [2020]
    Keywords : 3D hand pose estimation; real-time; Convolutional neural networks; Image analysis; Machine learning; AR; Mathematics and Statistics;

    Abstract : Estimating 3D hand poses from RGB images is a challenging task. In this work we construct efficient neural networks to regress sparse 3D skeletons consisting of 21 keypoints in the hand. Additionally heatmaps are regressed to locate the keypoints in 2D. READ MORE
