The results showed that there were significant differences among parameters of texture feature of the different land utilization. In the desertification, the mean and variance were comparatively high. The gray level was asymmetry, the contrasts between neighboring pixels were significant; while in water and irrigable land, the mean, variance was a little bit low, the grey level was symmetry; the mean, variance and gray level in the forest and dry land was between the above (desertification and water and irrigable land).

不同土地利用类型之间纹理特征参数差异明显，荒漠化土地的均值、方差值较高，灰度分布不均匀，相邻像元反差明显，内部变化剧烈；水体和灌溉耕地的均值、方差值很低，灰度值均匀，内部变化小；林地和旱耕地信息介于上述两类土地之间。

This classifier finished TM landcover by fuzzy logic reasoning, and the unclassified pixels increase K adaptively to be classified; It improved 2.7% and 2.9% in overall accuracy and Kapp coefficient compared with MLC, deceased 1% in Kapp coefficient and no change in overall accuracy compared with self-organizing network.

对拒分类的像元，自适应增加K值使其可分。该方法所得分类精度及Kapp系数与最大似然分类方法结果相比分别提高了2.7%和2.9%；与自组织网络相比，总精度相差不大，而Kapp系数低1%。

This portion also is better to be selected from the middle of the image in which the neighbored pixels have similar values.

最重要的是，中间部分的图像基本算法运作的比较好，变化比较小。

There is spatial correlation between the neighbored pixels , so there is the adjacent gray value .

大多数图象具有空间相关性，绝大部分相邻的象素点具有相近的灰度值。

Because more control can be obtained via binary pixelated arrays of metal pixels, as used on the National Ignition Facility to precompensate for the spatial gain variation of large glass amplifiers, we intend to adopt the binary mask method to spatially shape the Gaussian laser beam in "ShenGuang II" laser driver system.
