摘要
预处理对织物疵点检测来说是必不可少的,通过对传统的下采样预处理方法进行分析,指出其中的不足之处:图像下采样窗口大小是试凑得到的,针对此不足,根据织物纹理的周期性提出了一种确定下采样窗口的简单方法,加快了图像预处理的速度,并通过实验证明了此方法的优越之处。
Preprocessing is indispensable for fabric defects detection,this paper analyzes the traditional method of downsampling preprocessing,and points out its shortcoming that the window of downsampling is obtained by the method of trial and error.In view of the shortcoming of the traditional method,this paper pus forward a new simple method to determine the window of downsampling according to the periodicity of texture,and it accelerate the speed of preprocessing.At last,this paper verify the advantage of this method.
