  • Apparatus for recognition of approximate shape of an article
    Patent number: 4007440
    Abstract: Recognition of the approximate shape of a given article is accomplished by rotating the article by an angle of 180.degree. for thereby producing a direct projection, moving this direct projection perpendicularly onto a reference line for thereby obtaining a perpendicular projection of the article, computing the average pattern-classification value and the range of variation of pattern-classification value from the maximum and minimum ratios of the product of the largest width of the perpendicular projection of that article multiplied by the largest height thereof to the area of the article, and comparing the average pattern-classification value and the variable range with those of the reference pattern.
