   Sammanfattning : This thesis presents a comparison of M-estimator, BLAVE, and RANSAC method in point clouds registration. The comparison is performed empirically by applying all the estimators on a simulated data added with noise plus gross errors, ToF data and RGB-D data. The RANSAC method is the fastest and most robust estimator from the comparison. LÄS MER

3. 2. Calving Events Detection and Quantification from Time-lapse Images : A Case Study of Tunabreen Glacier, Svalbard

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Sigit Adinugroho; [2015]
   Nyckelord :;

   Sammanfattning : A fully automated method for detecting and measuring calving regions of a glacier is an important tool to gather massive statistical data of calving events. A new framework to achieve the goals is presented in this thesis. First, time-lapse images are registered to the first image in the set. LÄS MER
