摘要： A system for counting patterns in which each pattern in a scanning field is scanned along successive scanning lines and is sampled at successive points along each line to produce binary signals indicative of the presence or absence of the pattern at each sampling point. In order to avoid the problem of pores (holes or voids) in the patterns and the problem of concave pattern portions as seen in a given viewing direction perpendicular to the scanning direction, the digitized signals representing the original patterns are employed to produce mask signals which effectively eliminate the pores and concave pattern portions and which permit each pattern to be counted by counting a portion of the pattern that is convex as seen in the said viewing direction.
