This paper proposes a new robust tracking method to the moving object on image. Recently, technique of image processing to detect and track the moving object on time series images is important subject in the fields of intelligent transport systems and security systems. In the past, it was difficult to detect the moving object by the effect of changes in brightness which caused by the sunlight and so on. In order to solve this problem, some methods have been proposed. However, they are needed a background image or a template of the moving object. In here, we propose new detection and tracking methods based on Radial Reach Filter, and then introduce the process which recognizes situation of the moving object. Usefulness of our method is shown through experiments based on the real images.

This paper introduces a new method which enables to track the moving object in the image data. Detecting and tracking of the moving object in time-series image is important in the field of image processing. In the past, it is not easy to detect the moving object by the effect of the change in brightness. To solve this problem, a background image or a template image of the moving object is required. In this paper, a method that employs radial reach filter for tracking is proposed. The usefulness of our proposed method is demonstrated by experiments.

In Japan, complimenting one’s superiors is usually considered inappropriate. This is because the act of complimenting intrinsically has the connotation of evaluating the complimented party, and juniors are considered not possessing sufficient knowledge, experience or ability to evaluate their superiors. On the other hand, complimenting one’s superiors does not seem to be uncommon in English-speaking countries. The difference in perception on complimenting superiors could become source of confusion especially when Japanese college students start to work in English-speaking business environments. In order to deepen the understanding of how complimenting superiors work when communicating in English, the paper investigated the intentions of compliments and how they are expressed by analyzing and comparing American and Japanese movies and dramas depicting business environments where superior-subordinate relationships were clearly manifested. A new framework was created to categorize and analyze the compliments by combining 2 existing frameworks. Leech’s ‘The Tact Maxim’ was used for consideration. The results showed that when people complimented their superiors in English-speaking environments, the compliments were (1) meant to express high evaluations in all sincerity, (2) expressed to the superiors directly, (3) decisively expressed by evaluating the superiors or their deeds, and (4) expressed by concretely presenting facts.

In strain measurements for bridge maintenance, determining the position of the travelling vehicles is important because the strain response significantly vary depending on the position of the travelling vehicles. However, the conventional methods were not able to determine the position in a road width direction of the travelling vehicles accurately. This paper proposes the method to determine the position in a road width of that using image processing technique. In order to verify the proposed method, field measurements in a bridge in service were performed. Based on the experimental results, the proposal method was able to achieve accurately vehicle travelling position with practical processing speed.
