Abstract: | Change detection is an integral part of the analysis of satellite imagery, and it has been studied for several decades. It consists of comparing a registered pair of images of the same region and identifying the parts where a change has occurred, it allow to follow the evolution over time of a region of interest through technical changes upon detection So these images are a tool of choice in the management of natural resources. This requires a methodological approach appropriate image processing to the use of such data. In this work we compared the performance of three methods (Difference, ACP-Kmeans, Logmean) for the detection of changes in satellite images using the different evaluation metrics (FA, DR, Kappa, Precision, Recall, TC), and we were found that the ACP-Kmeans method gives a binary DC mask with better precision compared to other method.
