First, the input speech data is segmented into a plurality of input speech frames and the sample speech data is segmented into a plurality of sample speech frames. Then, the input speech frames and the sample speech frames are used to build a matching matrix, wherein the matching matrix comprises the distance values between each of the input speech frames and each of the sample speech frames. Next, the distance values are used to calculate a matching score. Finally, the similarity between the input speech data and the sample speech data is determined according to this matching score.Type: GrantFiled: October 20, 2005Date of Patent: April 27, 2010Assignee: National Cheng Kung UniversityInventors: Jhing-Fa Wang, Po-Chuan Lin, Li-Chang Wen

Patent number: 7418131Abstract: An image-capturing device and method for removing strangers from an image are described. First, a first image is input. Then, a control module determines if an unwanted object processing step is needed, and obtains a result. If the result is no, the first image is directly sent to an output module. If the result is yes, an image-identifying module begins to identify the target-image and the unwanted object in the first image, and then, an unwanted object processing module starts the step to process unwanted images. The unwanted object processing step can remove the unwanted object from an image and fill the left lacuna region. Afterwards, a second image is produced and sent to the output module.Type: GrantFiled: July 6, 2005Date of Patent: August 26, 2008Assignee: National Cheng Kung UniversityInventors: Jhing-Fa Wang, Han-Jen Hsu, Shang-Chia Liao
