Patent number: 7266290Abstract: A real-time rich media recording system. The system includes a capture module, a recording module and a random access module. The recording module real-time records a rich media source captured by the capture module as digital data. The recording module constructs a rich media relational table, and inserts an event label into the rich media relational table in response to an action instruction. The random access module stops the recording process of the recording module in response to an interrupt instruction, locates a location in the digital data, disables the event labels located after the location in the rich media relational table, and reinstates the recording module to record the rich media source at the position following the location in the digital data.Type: GrantFiled: August 8, 2002Date of Patent: September 4, 2007Assignee: CyberLink CorporationInventors: Aken Shiah, Andy Hsu, Chris Lin

Patent number: 6600830Abstract: An automatic feature extraction system for analyzing a face image and finding the facial features of the face. In the pre-processing stage, a second-chance region growing method is applied to determine a face region on the face image. In the feature extraction stage, three primary facial features, including both eyes and the mouth, are extracted first. Then other facial features can be extracted according to these extracted primary facial features. Searching feature points can be achieved by calculating the cost function of each point using a simple feature template. In addition, a genetic algorithm can be used to accelerate the process of searching feature points.Type: GrantFiled: November 16, 1999Date of Patent: July 29, 2003Assignee: Cyberlink CorporationInventors: Chun-Hung Lin, Ja-Ling Wu
