In this paper, a special preprocessing operations (filter) is proposed to decrease the effects of noise of textures. This filter using average of circular neighbor points (Cmean) to reduce noise effect. Comparing this filter with other average filters such as square mean filter and square median filter indicates that it provides more noise reduction and increases the classification accuracy. After applying filter to noisy textures some Local Binary Pattern (LBP) variants are used for featuredoaj:8c3ca773aec94ff6be41c49635379824 fatcat:oysyg3gvkndjnckhxhc3wz3mgm
