基于Db小波与中值滤波的安检图像噪声消除算法

Enhancement processing on Security Inspection Image Based on Db Wavelet Transform and median Filtering

摘要: 设置成像安检系统是机场等重要场所通常采用的安全措施。根据CT安检图像既含高斯白噪声又含脉冲噪声的特点,运用将Db小波变换与中值滤波相结合的综合去噪方法,以同时滤除高斯噪声和脉冲噪声,以获得更好的视觉效果。

Abstract: To setup imaging security inspection system is a common safety measure used in such important place as airport.According to the properties of noise in CT security inspection image,a method combining Db wavelet transform and median filtering is applied to cancel both Guass white noise and pulse noise,to get better visual results.
