binary noise meaning in Chinese

二进制噪声
二元噪声

At first , the paper confirms singular area by singular detection , then designs a series of low - pass filters that have different templates according to the different position in finger image for a local area , at last sets up gabor filter parameters according to the characteristics of fingerprint image . the improved enhancement algorithm has a better robust , and can preserve texture structure of singular area effectively . in binary noise clearance , the paper presents an algorithm that clears the biggish white speckles and black speckles
在指纹图像增强方面,本文针对传统的基于gabor滤波器指纹图像增强算法鲁棒性差以及通常会改变奇异区纹理结构的缺点,对原有算法进行了一些改进:首先通过检测奇异点确定奇异区,然后根据局部区域在指纹图像中的位置构建相应取值方式的低通滤波器并对该局部区域方向图进行滤波,最后根据指纹图像纹线的特点对gabor滤波器参数进行设置。
