Nowadays, ocean observatory networks, which gather and provide multidisciplinary, long-term, 3D continuous marine observations at multiple temporal spatial scales, play a more and more important role in ocean investigations. In this paper, we try to develop a portable smart device with online fish detection and tracking strategies by ARM7 microprocessor for ocean observatory networks, combining the...
In this paper, we try to develop a general framework of 3D shape reconstruction strategy with extremely rare point cloud extracted for fish ethology research. Particle filter is first taken to focus on fish trajectory tracking from monocular video sequence. The Speeded Up Robust Features (SURF) technique will be adopted to match the same tracking fish across the overlapping view fields with more stable...
Forest fire detection includes satellite monitoring, manual monitoring, aerial survey and so on. Compared with these expensive ways, a more practical fireproofing surveillance system needs to be built. An image capture system can be set up in the tower to sent fire image back to the command centre, using the short wave radios equipped for manual monitoring in the towers. Considering the finitude of...
Digital watermark for the protection of intellectual property rights has shown significant commercial value, but there are still some insufficiencies in the digital watermarking system in the theory and the means of realization. In this paper, we proposed a scheme based on the fingerprint watermark, and try to introduce biometrics in the watermark system. We wish to integrate the digital watermarking...
This paper proposes a high performance facial expression recognition method based on wavelet energy feature (WEF). As wavelet energy feature can discriminate the texture of expression images, it is used in facial expression recognition for the first time. Fisher's linear discriminants (FLD) can describe the details of the image, so we combine FLD with WEF. WEF is added to the image first, and then...
Nowadays, biometric verification occupies important position in people's daily life. Because fingerprints are easy to use and provide good performance, fingerprint identification is one of the most popular technologies. In order to maximize the robustness of fingerprint identification and to minimize the identification time, it is better to align the fingerprint first by referring the singular points...
