Mosaicking of Unmanned Aerial Vehicle Imagery in the Absence of Camera Poses
Remote Sensing, 2016 The mosaicking of Unmanned Aerial Vehicle (UAV) imagery usually requires information from additional sensors, such as Global Position System (GPS) and Inertial Measurement Unit (IMU), to facilitate direct orientation, or 3D reconstruction approaches (e.g.

Remote Sensing, 2019 To improve the efficiency and effectiveness of mosaicking unmanned aerial vehicle (UAV) images, we propose in this paper a rapid mosaicking method based on scale-invariant feature transform (SIFT) for mosaicking UAV images used for crop growth monitoring.

Retinal slit lamp video mosaicking [PDF]
, 2016 Purpose To this day, the slit lamp remains the first tool used by an ophthalmologist to examine patient eyes. Imaging of the retina poses, however, a variety of problems, namely a shallow depth of focus, reflections from the optical system, a small ...

Feature-based real-time endoscopic mosaicking
, 2022 S.695-700In the field of minimally invasive surgery one barrier in clinical practice is the limited field of view provided by endoscopic cameras. We propose an image mosaicking approach to extend the field of view for real-time visualization by stitching

Land Degradation &Development, EarlyView.ABSTRACT The use of Land Use Land Cover (LULC) analysis is a fundamental requirement for urban solid waste management (SWM); however, conventional LULC analysis methods are not well suited to the spatio‐temporal variability, multi‐sensor heterogeneity, and seasonal variations of highly dynamic urban environments.

A Coarse-to-Fine Image Warping Approach Using Trust Region Optimization for Orthoimage Mosaicking
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingOrthoimage mosaicking aims to make the seamline bypass obvious objects to produce seamless digital orthophoto maps. Nevertheless, stitching artifacts may still occur when obvious objects are inevitably crossed by the seamline or when the orthoimages are ...

Resource-Aware Image Mosaicking on Networks of Small-Scale UAVs [PDF]
, 2020 In this approach we estimate the depth structure of images captured by small-scale UAVs to guide the mosaicking of an overview image. We focus on efficient methods where initially only metadata and descriptors of corresponding points are transferred over
