| Abstract: | Classification on different weather conditions provides first step support for outdoor scene modeling,which is a core component in many different applications of image sequence analysis and computer vision.In this paper,an objective classification method on scenes with different weather conditions is presented with two steps based on stationarity and correlation test of image sequences.First of all,scenes with various weather conditions are considerably described,on which an objective classification standar... |
