CHANGE DETECTION

Algorithms of change detection in multi-temporal SAR images have received great interests for recent decades, and been widely applied in natural resource supervision activities. However, these algorithms still expose the limitation of detection accuracy due to inhenrent presence of speckle noise in[r]

CUSUM (cumulative sum) is a well-known method that can be used to detect changes in a signal when the parameters of this signalare known. This paper presents an adaptation of the CUSUM-based change detection algorithms to long-term signal recordingswhere the various hypotheses containe[r]
