Assessment of Accuracy in the Identification of Rock Formations from Aerial and Terrestrial Laser-Scanning Data

ISPRS International Journal of Geo-Information, 2018
Rock formations are among the most spectacular landscape features both for experts and the public. However, information about these objects is often stored inaccurately in existing spatial databases, their corresponding elevations are missing, or the ...

A Framework for the Objective Assessment of Registration Accuracy [PDF]

International Journal of Biomedical Imaging, 2014
Validation and accuracy assessment are the main bottlenecks preventing the adoption of image processing algorithms in the clinical practice. In the classical approach, a posteriori analysis is performed through objective metrics. In this work, a different approach based on Petri nets is proposed.

Quantifying Uncertainty in Land-Use/Land-Cover Classification Accuracy: A Stochastic Simulation Approach

Frontiers in Environmental Science, 2021
In numerous applications of land-use/land-cover (LULC) classification, the classification rules are determined using a set of training data; thus, the results are inherently affected by uncertainty in the selection of those data.

Delineation of Tree Patches in a Mangrove-Marsh Transition Zone by Watershed Segmentation of Aerial Photographs

Remote Sensing, 2020
Mangrove migration, or transgression in response to global climatic changes or sea-level rise, is a slow process; to capture it, understanding both the present distribution of mangroves at individual patch (single- or clumped trees) scale, and their ...

Using accuracy of self-estimated interest type as a sign of career choice readiness in career assessment of secondary students [PDF]

, 2008
A frequent applied method in career assessment to elicit clients' self-concepts is asking them to predict their interest assessment results. Accuracy in estimating one's interest type is commonly taken as a sign of more self-awareness and career choice ...
