Segmentation and Object-Based Image Analysis
2010This chapter focuses on segmentation of remotely sensed image data and object-based image analysis. It discusses the differences between pixel-based and object-based image analysis; the potential of the object-based approach; and, the application of eCognition software for performing image segmentation and classification at different levels of detail.

Object Based Image Analysis for Urbanized Areas
2010Urbanized areas are characterized by high complexity and diversity caused by repeating of many features – natural and man made. Object Based Image Analysis enables to reduce image complexity by its distribution into several levels of homogenous segments.

Swarm intelligence for object-based image analysis
2018Object-based image analysis (OBIA) approaches are often superior to the pixel-based classifications at very high resolution (VHR) remotely sensed images. Due to the similar spectral signatures of land-cover classes especially in urban areas, spatial information must be exploited to produce improved classification maps at finer resolutions. Segmentation

Geographic Object-based Image Change Analysis
2009Remote sensing is an effective tool for mapping earth surface objects and phenomena, and provides the sole means for comprehensive monitoring of land surface changes. Normally captured in an image form by sensors mounted on aircraft or satellites, remotely sensed data are spatially contiguous and temporally periodic measurements of the reflected or ...

Image Segmentation Methods for Object-based Analysis and Classification
2004Th e continuously improving spatial resolution of remote sensing (RS) sensors sets new demand for applications utilising this information. Th e need for the more effi cient extraction of information from high resolution RS imagery and the seamless integration of this information into Geographic Information System (GIS) databases is driving geo ...
