代码说明:

在本文,我们提出的自适应双边滤波 (ABF) 清晰度增强和噪声消除。亚洲债券基金增加的边坡,而生产的超调量不锐化图像,或下冲。它是从根本上不同于锐化掩模 (USM) 的锐度增强方法。这种新方法在边坡修复也明显区别于以往坡复原算法在这亚洲债券基金并不涉及检测的边缘或其方向或边缘轮廓的提取。在亚洲债券基金,通过变换与自适应偏移量和宽度范围筛选器通过直方图增强边坡。亚洲债券基金是能够平滑噪声,同时增强边缘和纹理图像中。亚洲债券基金的参数优化与培训过程。亚洲债券基金恢复图像是显著更清晰,比那些通过双边滤波恢复。基于 USM 锐化方法相比 — — 最优锐化掩模 (乌姆),ABF 恢复边缘是那些由乌姆,呈现一样锋利但没有光环出现在乌姆的工件恢复图像。在去除噪声,ABF 也优于双边滤波器和乌姆。我们证明了亚洲债券基金非常适合自然图像和文本图像。
