In this study, the authors introduce a newly developed flatfish grading system. Owing to the features of flatfish with and wide body, the general types of grading system are not easy to apply for it. Furthermore, the flatfish to be graded is alive such that the existing measurement and grading systems cannot be used for it as well. This study gives a solution for measuring and grading the flatfish with high speed and good accuracy. For this object, the authors developed flatfish measurement and grading system. This system consist of the feeding, conveying, measurement part and sorting part. Especially, the measurement part is made by vision based measuring technique which satisfies the given specification. The result from the experiment shows that the developed system is applicable for measuring and grading the flatfish sizes in variety.

评点是从历来古代中国文人所常用的文学批评方法。到明清时期，评点以小说和戏曲等民间文学为中心更普遍了。其主要的原因是由于当时出版业的发达和商业经济繁荣，出现了新的读者阶层。清初文学家而从事编辑及出版的张潮当时通过与文人交流的方式而读作品，同时借此互相交换信息和想法。可以说是今天的读书聚会活动。当时很多的文人为他的小品文集≪幽夢影≫做了评语。这本书成为被当时文人所爱读的畅销书。另外他的短篇小说选集≪虞初新志≫里的作品多是崭新而奇异的，每个作品都有他亲自做的评语，吸引了很多读者。因为≪幽夢影≫和≪虞初新志≫的新的评点方式和崭新的内容不但在当时，而且引起后人注目，因而产生了很多二流作品。从那样角度来看，我们可以肯定张潮的评点方式在一定程度上影响了文学批评和编辑及出版文化的发展。
