    • 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.

    • An edge-enhancement device for subjecting input image data to edge enhancement so as to generate output image data has an edge-component generator, a weighting processor, and an addition processor. The input image data is obtained from a frame image having a plurality of pixels, and the input image data contains luminance data. The edge-component generator generates an edge component of the input image data. The weighting processor applies a weight according to the value of the luminance data of each pixel to a calculated edge component of each pixel so as to generate a weighted edge component for each pixel. The addition processor adds the weighted edge component of each pixel to the input image data of the pixel so as to generate the output image data.
    • 用于对输入图像数据进行边缘增强以产生输出图像数据的边缘增强装置具有边缘分量生成器,加权处理器和加法处理器。 从具有多个像素的帧图像获得输入图像数据,并且输入图像数据包含亮度数据。 边缘分量生成器生成输入图像数据的边缘分量。 加权处理器根据每个像素的亮度数据的值对每个像素的计算的边缘分量应用权重,以便为每个像素产生加权的边缘分量。 加法处理器将每个像素的加权边缘分量与像素的输入图像数据相加,以产生输出图像数据。
