3D Modeling of Dormant Trees
The USDA Automatic Pruning Project
Dormant pruning is one of the most costly and labor-intensive operations in specialty crop production. During winter, a large crew of trained seasonal workers has to carefully remove the branches from hundreds of trees using a set of pre-defined rules.
An Approach-Path Independent Framework for Place Recognition and Mobile Robot Localization in Interior Hallways
This work is about self-localization by a robot using stereo images of the environment. We use 3D-JUDOCA features that have high robustness to viewpoint variations. We present a novel cylindrical data structure — the Feature Cylinder — for expediting localization with two hypothesize-and-verify frameworks.
Many object tracking algorithms implicitly or explicitly use a coarse segmentation of each target object using a simple mask such as a rectangle or an ellipse. This coarse segmentation results in several problems in tracking. If the mask is too large, extra background pixels will be included causing target drift.
Our previous work showed that combining segmentation and tracking gives improved tracking performance compared to bounding-box approaches. The key idea is to define a probability distribution over the pixels belonging to each of the targets and the background.
The aim of this project is to provide the accurate location of ground objects in a world coordinate system using vision-enabled unmanned aerial vehicles (UAVs). Our approach pursues to find the correct registration between aerial images and reference image.
