| Abstract: | With the Radarsat radar image as the data source,the authors carried out the variation detection study in Chengdu area.By choosing proper distribution and utilizing maximum likelihood regularity,the image variation in the urban area was investigated.On the basis of the detection of Radarsat data variation,the urban area variation was divided into two types,namely smooth transition and abrupt change,which were assigned respectively to homoplasmic area and alloplasmic area.These two types were detected separately by algorithm.Practice shows that the result is fairly satisfactory. |
