Vision-based animal behavior analysis is a critical and interesting problem for both biologists and computer vision scientists. In this paper, an automatic system for detecting behaviors of fruit flies is presented. Firstly, we propose an ellipse model to fit the contours of fruit flies, which efficiently detects fruit flies in a single frame. Then we associate the detection results together to form...
According to the features of Dai Characters and the status quo of Dai Information processing, this paper puts forward a making method of common outline fonts of the Dai characters. Based on the analysis on the types of outline fonts, outline extraction method of Dai font is designed and realized in Linux. Dai outline font as basis for Dai information processing provides strong support for promoting...
This paper puts forward an improved background subtraction of moving object detection under fixed camera condition. First of all, considering the pixels neighboring relativity, the algorithm through the interval pixels establishment of Gaussian mixture model instead of the traditional point by point establishes Gaussian mixture model in background subtraction. Then, combining the adaptive background...
