   Sammanfattning : This thesis treats static and dynamic surface characterization using radiometric and Fourier optical methods. A Fourier optical method has been developed for real time image processing in paper production and printing applications. LÄS MER

3. 2. Optimization Methods for 3D Reconstruction : Depth Sensors, Distance Functions and Low-Rank Models

   Författare :Erik Bylow; Mathematical Imaging Group; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; 3D Reconstruction;

   Sammanfattning : This thesis explores methods for estimating 3D models using depth sensors andfinding low-rank approximations of matrices. In the first part we focus on how toestimate the movement of a depth camera and creating a 3D model of the scene. LÄS MER

4. 3. The Texture-Transform : An Operator for Texture Detection and Discrimination

   Författare :Alireza Tavakoli Targhi; Jan-Olof Eklundh; Arnold Smeulders; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datalogi;

   Sammanfattning : In this thesis we present contributions related to texture detection and discrimination to be used for analyzing real world images. Many computer vision applications can benefit from a fast and low dimensional texture descriptor. LÄS MER
