Algorithms for metric 3d reconstruction of scenes from calibrated image sequences always require an initialization phase for fixing the scale of the reconstruction. Usually this is done by selecting two frames from the sequence and fixing the length of their base-line. In this paper a quality measure, that is based on the uncertainty of the reconstructed scene points, for the selection of such ...

We propose a system for performing structural change detection in street-view videos captured by a vehiclemounted monocular camera over time. Our approach is motivated by the need for more frequent and efficient updates in the large-scale maps used in autonomous vehicle navigation. Our method chains a multi-sensor fusion SLAM and fast dense 3D reconstruction pipeline, which provide coarsely reg...

Objective (s): Various iterative reconstruction algorithms in nuclear medicine have been introduced in the last three decades. For each new imaging system, it is wise to select appropriate image reconstruction algorithms and evaluate their performance. In this study, three approaches of image reconstruction were developed for a novel desktop open-gantry SPECT system, PERSPECT, to assess their p...

This paper discusses localisation and mapping techniques based on a single camera. After introducing the given problem, which is known as monocular SLAM, a new camera agnostic monocular SLAM system (CAM-SLAM) is presented. It was developed within the scope of this work and is inspired by recently proposed SLAM-methods. In contrast to most other systems, it supports any central camera model such...

There are limited studies in the literature regarding reconstruction of bilateral anterior cruciate ligament (ACL) injuries a single-stage setting. However, there have been no published describing simultaneous revision reconstructions previously reconstructed ACLs. We present case 37-year-old male who underwent previous both ACLs at an outside hospital and presented to our outpatient clinic wit...
