Compared with the global threshold, the new method makes the denoised image more clear and fits to visual performance.
新方法从各种衡量指标上看也优于全局阈值去噪法。
参考来源 - 基于小波变换的图像去噪算法The global threshold is adapted to eliminate the influence of noise further. Finally,images are computed with some auto-focusing method carefully,which are calculated by the adaptive method.
首先通过一个基于局部小窗口的自适应门限将边缘像素和非边缘像素区别开来,然后再加上一个全局门限来进一步滤除噪声的影响,最后用一些自动聚焦算法来计算经过自适应处理后的图像,画出它们的聚焦曲线。

The paper firstly discussed two ways for image segmentation:image segmentation by global threshold and image segmentation by dynamic threshold.
首先讨论了图像阈值分割的两种方法：全局阈值图像分割和动态阈值图像分割。
Based on global threshold, a new dynamic thresholding approach is proposed which is adjusted with th weighting of the difference between neighbor average grey and global threshold.
以全局阈值为基础，用邻域平均灰度与全局阈值之差的加权值对其进行调整，从而形成一种新的动态阈值分割法。
Compared with the fixed threshold and the global threshold algorithms, the proposed method obtains better detection effects for clouds in small, broken bits and weak contrast clouds.
