Abstract:
Cyanobacteria bloom-forming in Taihu Lake has already become an environmental problem which is concerned with the whole society and the government. It is difficult for the department of water-environment monitoring to monitor the bloom on the lake timely and accurately. By using template matching process,the territorial waters information of Taihu Lake is extracted firstly. To tackle the problem of Cyanobacteria under clouds cover,the problem is divided into two,one is under the clouds cover,the other is under no clouds. Experimental results on hundreds of MODIS images show that the proposed method is effective with satisfactory accuracy. Furthermore,spatio-temporal analysis of Cyanobacteria during the year 2006 reveals the underlying knowledge of its year pattern,which can provide decision support information for the administrative departments.
