  1. 1. DirCNN: Rotation Invariant Geometric Deep Learning

    Master-uppsats, KTH/Matematisk statistik

    Författare :Yannick Saive; [2019]
    Nyckelord :;

    Sammanfattning : Recently geometric deep learning introduced a new way for machine learning algorithms to tackle point cloud data in its raw form. Pioneers like PointNet and many architectures building on top of its success realize the importance of invariance to initial data transformations. These include shifting, scaling and rotating the point cloud in 3D space. LÄS MER

  3. 2. Rotational Invariant Convolutional Neural Networks for Prostate Cancer Classification

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Joel Ekelund; [2017]
    Nyckelord :Convolutional Neural Networks; rotation invariance; deep learning; automated Gleason grading; Mathematics and Statistics;

    Sammanfattning : Prostate cancer was in 2012 the second most common type of cancer for males globally. To be able to treat prostate cancer in the most effective way it is important to know how aggressive the cancer is. This aggressiveness is graded using the Gleason score. LÄS MER

  4. 3. Rotation Invariant Registration of 2D Aerial Images Using Local Phase Correlation

    Master-uppsats, Institutionen för informationsteknologi

    Författare :Ping Lu; [2013]
    Nyckelord :;

    Sammanfattning : Aerial image registration requires a high degree of precision. In order to improve the accuracy of feature-based registration, this project proposes a novel Log-Polar Transform (LPT) based image registration. Instead of using the whole image in the conventional method, feature points are used in this project, which reduces the computational time. LÄS MER
