Short-lasting rhythmic activity in intracranial electroencephalogram (iEEG) in the frequency range of 80 to 500 Hz is regarded to be a promising biomarker of epileptogenicity. This activity is referred to as high-frequency oscillation (HFO), and its detection from iEEG is considered the first step to several applications. In this study, several multi-channel algorithms for HFO detection are proposed...
A lymphoepithelioma-like carcinoma (LELC) is a rare neoplasm of the urinary bladder. A 71-year-old man presented with gross hematuria for several weeks. On cystoscopy, a solid sessile tumor was observed in the bladder dome. A partial cystectomy was performed. Histopathological findings showed that the lesion was a pure LELC of the urinary bladder. The patient was followed up for 24 months without...
In this work, we propose a framework to build a billiards tutoring system based on broadcasting nine-ball video analysis. A robust table detection module is developed by mapping the displayed video frames to a predefined billiard table model. In addition, we detect balls and trace their positions at every time instant. The real-world spatial relationships between the table and the balls are used to...
This paper proposes a mining-based method to achieve event detection for broadcasting tennis videos. Utilizing visual and aural information, we extract some high-level features to describe video segments. The audiovisual features are further transformed to symbolic streams and an efficient mining technique is applied to derive all frequent patterns that characterize tennis events. After mining, we...
