Tick-mark recognition is a key step for automatic reading of analog instrument with computer vision techniques which is called for in many automatic processes among industries. As many factors result in the tick-mark distortion in the sampled image such as the generally stained surface of instrument, or/and reflection and refraction of light, the accuracy and robustness of tick-mark reading are directly or indirectly weakened. Double image segmentation algorithm (DISA) is employed to solve this problem which makes coarse segmentation with structural parameters of instruments, and makes accurate segmentation with gray difference between tick-marks and their background. Tests have been conducted with 640 * 480 pixel industry camera and 4 kinds of pointer pressure meter, and the results show that read-out rate of tick-mark in pointer meter reached 100% at sufficient illumination and 76% at insufficient illumination for air packed instrument. In addition with oil packed instrument, DISA still experienced 64% recognition in comparison with 0 success record by Hough Transformation.
In order to make our country business Japanese talents to better meet the needs of the current society, it must be sure to set up the courses in business Japanese teaching. However, at this stage in the business of Japanese talent training process and no clear objectives, therefore, it leads to more problems in its teaching process. Articles on contemporary business Japanese teaching innovation question has carried on the comprehensive analysis and research, aiming at problems existing in the teaching process of business Japanese, and put forward the targeted countermeasures of innovation, designed to better improve our country contemporary business Japanese teaching level and quality.
Abstract. Language and culture have very close relationship. Language is the carrier of culture, and culture can guide language in turn. So, to master a language, it is required to deeply analyze the culture. Japanese is a national language of Japan has dense Japanese culture connotation. When we learn Japanese, we should carefully learn Japanese culture. Thus, Japanese teachers should attach importance to introducing Japanese culture in Japanese teaching. However, Japanese teaching excessively values cultivation and improvement of basic listening, speaking, reading, writing and translation ability, but greatly neglects Japanese culture introduction in teaching. To change such situation, we must practically and properly introduce Japanese culture in Japanese teaching and really improve Japanese teaching quality and level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
