PCT No. PCT/JP91/00709 Sec. 371 Date Mar. 18, 1992 Sec. 102(e) Date Mar. 18, 1992 PCT Filed May 28, 1991 PCT Pub. No. WO91/19035 PCT Pub. Date Dec. 12, 1991.A method of inspecting cleanliness of top sliber. The method classifies detected defects into pillwise defects and vegetal defects by introducing roundness, slenderness, gradation, dispersion, area, shape, gradation ratio, and length discernment against image signals of inspected top slibers picked up by an image sensor. An apparatus for inspecting cleanliness of top sliders is utilized. The apparatus initially picks up an image of uniformly spread top slibers conveyed to the apparatus and then processes the image signal with an image processing unit provided therefor. The method involves classifying defects on the top sliber into pillwise defects and vegetal defects in the top sliber based on the generated image signal. The classifying involves the steps of (i) establishing conditional section membership functions for features of defects, (ii) establishing conclusion section membership functions for determining a probability of being a defect against said classified defects, (iii) establishing a fuzzy rule for relating said features of defects with said probability of being a defect against the defects; and (iv) classifying the defects based on fuzzy reasoning derived from the conditional section membership functions, the conclusion section membership functions, and said fuzzy rule.
