Methods Marshland areas near high endemic villages of schistosomiasis in the Poyang Lake region were selected. Corresponding map was digitized and (Landsat 5 TM) the image was corrected according to the digital map. The image where water and land shifted during floody and dry seasons was extracted and classified by unsupervised method. The image in dry seasons was calculated by both Normalized Difference Vegetation Index and Tasseled Cap model. Traditional snail survey was done at the same areas and recorded the geographic position by Geographic Position System. Some cultured lands inside the embankment and water pound in marshland areas were selected as control group. Results The image of pilot areas was classified into 10 classes.

A new algorithm of low bit rate image compression was proposed. Firstly, the edge informations of the input image were detected with SUSAN operator, then the detected edge informations were en hanced with edge enhancement method. Finally, the enhanced edge informations were added to the decoded input image to form the final compressed image.

The first the relation of AD model and the energy variety of image is educed by thermal diffusion and the diffusion equations based energy flux, and proves the image processing by energy flux sufficing maximum-minimum principle, the variety of image energy is equivalent to that of image intensity.

首先通过热扩散及热扩散方程、基于能量流的扩散方程，导出了向异性扩散模型与图像能量的变化过程之间的关系，并证明了利用能量流方法获得的图像处理过程同样满足极大极小原理。

In this time, we can recognize the number image depending on the location of the end-point. If the y-coordinate of the end-point is bigger than half of the height of the number image, the recognized result is 6. Else the result of recognition is 9. Then if there are two end-points and there is no trifurcate point, the possible recognition result of the number image is 2, 3, 5 or 7. Here, we need to recognize the number image by dint of the end-point directions and locations.

最后，我们根据特征提取的结果进行分类识别，如果没有端点、没有三叉点，则识别结果为0；如果无端点，两个三叉点，则识别结果为8；如果只有一个端点、一个三叉点，则识别结果可能为6或9，这时只需考虑端点的位置，即可将6和9区分开来；如果有两个端点、无三叉点，则识别结果可能为2、3、5、7，这时需要加入端点的位置和方向辅助判断。
