MPS-based information extraction method for remotely sensed imagery: a comparison of fusion methods
Ge, Yong1,2; Bai, Hexiang1,3
AbstractRecently, multiple-point simulation (MPS) was introduced to increase the accuracy of information extraction from remotely sensed imagery by incorporating structural information through a training image. An important procedure in the MPS-based information extraction method is the fusion of two probability fields from two different classifiers, extracting spectral and spatial structure information. In previous studies the fusion process was accomplished using the theory of evidence and the theory of consensus. It has been shown that these fusion methods each have their own capabilities and characteristics for different data under different circumstances. This paper investigates primarily the advantages and disadvantages of three different types of fusion methods: evidence-based, consensus-based, and probability-based, and then compares the fusion results through an accuracy assessment. For validation purposes, we selected two remotely sensed images taken in different areas and with distinct structural characteristics of roads. Both images, from Satellite Pour l'Observation de la Terre 5 (SPOT5) with spatial resolution of 10 m, were used to investigate the performance of the three fusion methods in extracting road information with distinct structural characteristics from the images. A comparison of the different fusion methods can assist users in selecting the appropriate fusion method for the given data characteristics. Based on the results of two experiments, the relationships between these fusion methods are further investigated.
