In this paper, based on the leg movement mode analysis, a novel human computer interaction (HCI) scheme with which users can interact with computer is presented. Firstly, an efficient valley point location algorithm is proposed to detect and separate the left and right leg, then an extended Mean Shift tracking algorithm with Kalman filter is applied to track the leg's movement, finally the movements...
To improve the convergence performance of the adaptive filtering and avoid excessive sub-band decomposition, sub-band decomposition method to decompose the whole band based on the autocorrelation matrix eigenvalue of the signal is proposed. Performance analysis demonstrates that, comparing with traditional algorithms, the proposed method can efficiently perform better with an equal number of sub-bands...
This paper addressed super-resolution technology of image sequences. The image sequences included a lot of redundant and nonredundant information. To enhance the information of SR image, the nonredundant information should be fused into the SR image as much as possible. This paper proposed a novel SR algorithm based on clutter prediction, which extracted and employed the nonredundant information to...
The optical flow equation (OFE) is important to estimate the motion field in image processing. However the traditional OFE algorithm isn't robust. Ignoring this problem, the large error will happen. In this paper, the conditions of OFE had been discussed, and the OFE algorithm had been improved, improvement had rendered the algorithm reliable performance. Then, a new motion estimation algorithm on...
The velocity measuring system includes two classes, radar and lidar. However, these systems usually detect single vehicle. Many cities road, a lot of cameras have been set. They often use to watch vehicles' peccancy, but they can't measure vehicles velocity. In this paper, we introduce a new velocity measuring system with camera. It can measure vehicles velocity by itself. If we upgrade cameras set...
