Object based image analysis for remote sensing

open access: yesISPRS Journal of Photogrammetry and Remote Sensing, 2010
AbstractRemote sensing imagery needs to be converted into tangible information which can be utilised in conjunction with other data sets, often within widely used Geographic Information Systems (GIS). As long as pixel sizes remained typically coarser than, or at the best, similar in size to the objects of interest, emphasis was placed on per-pixel ...

Object-based multiscale segmentation incorporating texture and edge features of high-resolution remote sensing images [PDF]

open access: yesPeerJ Computer Science, 2023
Multiscale segmentation (MSS) is crucial in object-based image analysis methods (OBIA). How to describe the underlying features of remote sensing images and combine multiple features for object-based multiscale image segmentation is a hotspot in the ...

Using object-based image analysis to detect laughing gull nests

open access: yesGIScience & Remote Sensing, 2021
Remote sensing has long been used to study wildlife; however, manual methods of detecting wildlife in aerial imagery are often time-consuming and prone to human error, and newer computer vision techniques have not yet been extensively applied to wildlife
