plus Abstract :

My research goal is to detect and distinguish targets from the changes between a pair of remotely sensed pictures. First, the changes are detected through an iterative principal component analysis. Then we use an entropy K-Means algorithm followed by a Markov Random Field segmentation in order to classify the changed zones on the picture. Later, we will use a higher level approach in order to recognise some patterns and discard false positives.
