彩色图像迭代滤波算法
Color image iterative filtering algorithm
摘要
Abstract
As to the color images corrupted by impulse noise, a series of iterative filtering algorithm based on noise detection is proposed.An impulse detector is presented to find out all pixels that are considered as noise before filtering.If a pixel is considered as noise,it will be replaced by a pixel in the neighborhood which is noise-free during filtering procedure later; otherwise, it is unchanged.The conventional filters are improved as the filtering algorithm later.The conventional filters include the vector median filter, the basic vector directional filter, and the directional distance filter.As demonstrated by the extensive experimental results,all the proposed filtering methods compare favorably with conventional techniques in the capabilities of noise attenuation and details preservation, in both quantitative and qualitative measures.关键词
