摘要
定义了图像的光滑性与一致光滑性,引进了上、下光滑函数的概念,给出了一种描述图像结构的方法,进而讨论了所得图像的性质。提出了光滑滤波的方法,用这种方法对数据进行上、下滤波,原理简单,容易实现,它可以为数值微分提供较为满意的滤波曲线。
Smoothness and unanimous smoothness of images are defined. The concept of up and down smooth functions are introduced. A method for describing the image structures is proposed. The properties of the stated image are discussed, A smooth filtering method is given. The principle of up and down data filtering is simple and easy to be implemented, by which satisfied filtering curves could be provided for digital differentiating.
