Automated methods for image detection of cultural heritage: Overviews and perspectives

open access: yesArchaeological Prospection, Volume 30, Issue 2, Page 153-169, April/June 2023., 2023
Abstract Remote sensing data covering large geographical areas can be easily accessed and are being acquired with greater frequency. The massive volume of data requires an automated image analysis system. By taking advantage of the increasing availability of data using computer vision, we can design specific systems to automate data analysis and ...

A Meta-Methodology for Improving Land Cover and Land Use Classification with SAR Imagery

open access: yesRemote Sensing, 2020
Per-point classification is a traditional method for remote sensing data classification, and for radar data in particular. Compared with optical data, the discriminative power of radar data is quite limited, for most applications.

Effect of Image-Processing Routines on Geographic Object-Based Image Analysis for Mapping Glacier Surface Facies from Svalbard and the Himalayas

open access: yesRemote Sensing, 2022
Advancements in remote sensing have led to the development of Geographic Object-Based Image Analysis (GEOBIA). This method of information extraction focuses on segregating correlated pixels into groups for easier classification.

Mangrove changes over the past decade in South and Southeast Brazil using spaceborne optical and SAR imagery

open access: yesAnais da Academia Brasileira de Ciências, 2023
Mangroves occur in the tropics and subtropics. This region is constantly covered by clouds and therefore highly challenging to map and monitor. Technological advances in remote sensing have increased the flexibility of performing such analyses.

Real World Objects in GEOBIA through the Exploitation of Existing Digital Cartography and Image Segmentation

open access: yes, 2010
Descriptions of Geographic Object-Based Image Analysis (GEOBIA) often identify image segmentation as the initial step. This may be reasonable in some cases, but segmentation might also be considered a “black art,” due to its image dependence and the ...

Pixel and Object-Based Machine Learning Classification Schemes for Lithological Mapping Enhancement of Semi-Arid Regions Using Sentinel-2A Imagery: A Case Study of the Southern Moroccan Meseta

open access: yesIEEE Access, 2021
Mapping lithological units of an area using remote sensing data can be broadly grouped into pixel-based (PBIA), sub-pixel based (SPBIA) and object-based (GEOBIA) image analysis approaches.

Comparison of PBIA and GEOBIA classification methods in classifying turbidity in reservoirs

open access: yes, 2022
Our goal is to compare the performance of Classification and Regression Tree, Naive Bayes and Random Forest algorithms, from supervised image classification, and approaches on Pixel-Based Image analysis (PBIA) and Geographic Object-Based Image Analysis ...

Map legend and response design : how do they affect accuracy of GEOBIA results

open access: yes, 2016
The legend used to map a given region is most of the time the first characteristic assessed by end users. In GEOBIA, the choice of a classification system is primarily guided by the scale of analysis and the underlying data model.
