Markerless Endoscopic Registration and Referencing [PDF]
, 2006 Accurate patient registration and referencing is a key element in navigated surgery. Unfortunately all existing methods are either invasive or very time consuming. We propose a fully non-invasive optical approach using a tracked monocular endoscope to reconstruct the surgical scene in 3D using photogrammetric methods.

Markerless human motion transfer [PDF]
ACM SIGGRAPH 2004 Sketches on - SIGGRAPH '04, 2004 In this paper we develop a computer vision-based system to transfer human motion from one subject to another. Our system uses a network of eight calibrated and synchronized cameras. We first build detailed kinematic models of the subjects based on our algorithms for extracting shape from silhouette across time [A 3D reconstruction algorithm combining ...

Markerless Genome Editing in Competent Streptococci [PDF]
, 2016 Selective markers employed in classical mutagenesis methods using natural genetic transformation can affect gene expression, risk phenotypic effects, and accumulate as unwanted genes during successive mutagenesis cycles. In this chapter, we present a protocol for markerless genome editing in Streptococcus mutans and Streptococcus pneumoniae achieved ...

Markerless Gene Deletion System for Sphingomonads [PDF]
Applied and Environmental Microbiology, 2012 ABSTRACT Here, we suggest that natural streptomycin resistance of many sphingomonads resides within rpsL . We constructed a dominant, streptomycin-sensitive rpsL allele and demonstrated its use as a counterselection marker in several sphingomonads.

Autonomous Aerial Refueling Ground Test Demonstration—A Sensor-in-the-Loop, Non-Tracking Method
Sensors, 2015 An essential capability for an unmanned aerial vehicle (UAV) to extend its airborne duration without increasing the size of the aircraft is called the autonomous aerial refueling (AAR).

AR Enabled IoT for a Smart and Interactive Environment: A Survey and Future Directions
Sensors, 2019 Accompanying the advent of wireless networking and the Internet of Things (IoT), traditional augmented reality (AR) systems to visualize virtual 3D models of the real world are evolving into smart and interactive AR related to the context of things for ...

Markerless 3D Face Tracking [PDF]
, 2009 We present a novel algorithm for the markerless tracking of deforming surfaces such as faces. We acquire a sequence of 3D scans along with color images at 40Hz. The data is then represented by implicit surface and color functions, using a novel partition-of-unity type method of efficiently combining local regressors using nearest neighbor searches ...

Single Camera-Based Remote Physical Therapy: Verification on a Large Video Dataset
Applied Sciences, 2022 In recent years, several systems have been developed to capture human motion in real-time using common RGB cameras. This approach has great potential to become widespread among the general public as it allows the remote evaluation of exercise at no ...
