Abstract :
In this paper, we propose to identify the number of categories that can be retrieved from a very high resolution SAR data. The evaluation is done on TerraSAR-X high resolution Spotlight data and the retrieved categories are semi-automatically annotated using as feature vector the Gabor filters; as a classifier the Support Vector Machine, and for ranking the suggested images the relevance feedback. The visualization of the tool was enhanced compared with our previous implementation in order to support the users in his/her approach to search the patches of interest in a large repository. Our dataset consist in 43 scenes that cover as much as possible all the regions over the world. A total of 352 categories are identified that contain urban and non-urban categories.
