Underwater image segmentation becomes a difficult and challenging task due to various perturbations present in the water. In this paper we propose a novel method for underwater image segmentation based on M-band wavelet transform and human psychovisual phenomenon(HVS). The M-band wavelet transform captures the texture of the underwater image by decomposing the image into sub bands with different scales...
The purpose in this study is visualizing brain functional activities during taking a favorite food using Near Infra-Red Spectroscopy (NIRS). Many appointments and systems that aim to provide happiness for improving quality of life in the users have been constructed. The creations must integrate a common and plausible happiness indicator into their module; however, almost all of them do not have the...
The authors propose a new biometric modality, called a screen fingerprint, for active authentication. A screen fingerprint is acquired by taking a screen recording of the computer being used and extracting discriminative visual features from the recording. The authors demonstrate that the screen fingerprint of an operator captures enough unique human qualities to be usable as a biometric for authentication...
Significances of information technology for teaching and learning were discussed, and students' Preference to applying information technology in graduation design was investigated. Tutorship applying information technology has advantages, such as space-time flexibility, visualization, digitalization and mass information. It can't replace traditional means entirely; however, two means should have complementary...
With the improving of ubiquitous technology, ubiquitous learning combined with tiny ubiquitous computing devices has provided great educational effect for users. In the aspect of learning process in traditional ubiquitous learning systems, in some systems users need to follow the instruction of the systems, and in other systems, they adapt to users. However, these may result to that users are hard...
