Segmentation techniques applied to remotely-sensed data can increase the accuracy of
object extraction, particularly for scenes of natural homogeneous regions such as …

In this paper, an image segmentation algorithm based upon hierarchical step-wise
optimization with a composite merge criterion is presented. In hierarchical step-wise …

This Letter describes the application of a Hierarchical Stepwise Segmentation Algorithm to
SAR mosaic images. The objective was to obtain an efficient procedure which can be used …

Four segmentation algorithms were tested and evaluated for their application to agricultural
remote sensing image data. Each of the four algorithms were distinctly different in their …
