Video summary is important for users to quickly understand the video content. In this paper, first, some selection principles of video content and an importance evaluation model of movie summary are analyzed. Then, a movie summary generation system which includes three subsystems such as video management and retrieval subsystem, video clips selection subsystem, and video summary generation subsystem...
According to the image quality degradation in super-resolution reconstruction, we present a new algorithm for a single image super-resolution reconstruction to improve the image resolution. Considering the limitations that the extracted features of low-resolution image can not adapt to image direction changes, we propose a new feature-extracted method, and we build a new global optimization framework...
Fractional Fourier Transform (FRFT) is a time-frequency analysis tool which contains the time-frequency information of the signal at the same time. In this paper, we use FRFT as feature extraction method for recognizing smile emotion. Based on the FRFT, the original signal is transformed into complex-values containing amplitude and phase information. We adopt to use amplitude, phase and complex information...
For natural image segmentation, due to features from a single image are hard to describe the complex scene information, this paper presents a new method based on the fusion model evaluation index PRI to fuse color histogram features in 3 color spaces, RGB, XYZ, LUV, and texture features. We experiment on images from Berkeley segmentation databases and compare the quantitative and qualitative experimental...
Recently, the video-based technologies play an important role in monitoring fields, including the detection, identification and tracking of moving object. This paper designs an effective pedestrian detection and tracking algorithm in the traffic environment. Firstly, extract the moving prospect from the background in the video images, using conventional frame difference algorithm. The moving targets...
This paper presents a new method of applying laser sensor to obtain road boundary points in order to solve the road detection problems of outdoor cleaning mobile robot. This method makes full use of the advantages of laser sensor and realizes the recognition of road detection in real-time. The road boundary recognition algorithm including the feature extraction and coordinate calculation is proposed...
The traffic safety monitoring technology becomes an active research field due to the development of the city's transport system. In this paper, we design a warning method in traffic video monitoring through analyzing vehicle states. This method is based on image analysis and processing technology, extracting the information of the characteristics of the movement of vehicles through detecting and tracking...
