Deep Learning Meets OBIA: Tasks, Challenges, Strategies, and Perspectives

CoRR
Deep learning has gained significant attention in remote sensing, especially in pixel- or patch-level applications. Despite initial attempts to integrate deep learning into object-based image analysis (OBIA), its full potential remains largely unexplored.

A Procedure for Semi-automatic Segmentation in OBIA Based on the Maximization of a Comparison Index [PDF]

, 2014
In an Object Based Image Analysis Classification (OBIA) process, the quality of the classification results are highly dependent on segmentation. However, a high number of the studies that make use of an OBIA process find the segmentation parameters by making use of trial-and-error methods.

A multi-scale classification method for rocky desertification mapping in the red-bed area of northwestern, Jiangxi, China

Geocarto International, 2023
Currently, the monitoring of rocky desertification(RD) is concentrated in the karst area, whereas the study in red-bed areas is rare. In this paper, we present a multi-scale classification framework for RD monitoring based on spectral-spatial features ...
