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。
