We present a refinement framework for background subtraction based on color and depth data. The foreground objects are segmented based on color and depth data independently, in which all of the existed background subtraction (BGS) methods can be applied. The two detected foregrounds will be very inaccurate in some situations such as shadowing and color camouflage. We focus our works on refining the...
This paper presents an improved Mean Shift tracking algorithm. It extends the classic Mean Shift tracking algorithm by combining color and texture features. In the proposed method, firstly, both the color feature and the texture feature of the target are extracted from first frame and the histogram of each feature is computed. Then the Mean Shift algorithm is run for maximizing the similarity measure...
Exploration techniques of video knowledge have been proposed for years to help people discover the details about videos. However, existing systems still yield limited information for users. In this paper, we present a video knowledge browsing system, which can establish the framework of a video based on its summarized contents and expand them by using online correlated media. Thus, users can not only...
Duplicated web pages responded by search engines not only waste valuable storage, but also aggravate burdens of userspsila browse. Web page de-duplication can effectively improve the information retrieval. This paper proposes pretreatment of web pages to improve the effectiveness and efficiency of web page de-duplication based on feature code according to the principle of data clearing. This paper...
A lot of vital defects appear in the process of fabrication of IC wafer. Material defect which mainly causes circuits to be connection failure is an important factor of reducing the yield of IC. So the inspection of material defect is one of the most important things to do for guaranteeing the quality of IC. In this paper, a machine visual test system is designed with AOI (automated optical inspection)...
