A method of color image salt and pepper noise filtering based on uniform space is proposed. To overcome the weakness of traditional median filtering may bring in other colors

a vector sorting method which is consistent with human’s ability of color recognition is proposed. In the Lab space

the Euclidean distance between pixels points is proportional to the actual color difference

on which the vector sorting is established. According to sorting result

as criteria uses method of median filtering to remove the noise. The results are compared with other filtering methods such as HSV

VMF andBVDF. Experimental results show that the method can not only improve image quality

but can protect color information of image better

and it is better than the traditional denoising algorithm of color image.
