This paper presents an automatic event detection system fusing low and mid level features for soccer videos. We first employ an improved approach for Shot Boundary Detection with color and our mean-gradient feature. Then we classify the shots into two view types. We also perform a template-based replay detection for each shot. Play-break sequences are then generated using a rule-based method. We devise...
An approach for improving the z-axis resolution of spiral CT using super resolution (SR) technology in the post processing step is proposed in this work. As the spiral CT has the ability to produce over-lapped slice images without over-lapped scanning, the sub-slice thickness shifts in z-axis require neither change in hardware nor any additional radiation dose. The thinner slice is obtained by combining...
Protein classification plays an important role in the research in Bioinformatics. Many discriminative methods, including the SVM based algorithms are used to do this job. In order to use these methods, variable length protein sequences must be converted into fixed-length dimensional vectors. The current work presents a new method of converting sequences into vectors. The method first constructs profile...
An approach for improving the z-axis resolution of MRI using super resolution (SR) technology in the post processing step is proposed. The 2D multi-slice MRI is often anisotropic, the z-resolution lower than the in plane resolution. And the isotropic is necessary for certain diagnostic while the truly isotropic image is hardly obtained. In this case the super resolution is an efficiency post-processing...
