Publication number: 20070139659Abstract: A method and device for capturing speckles are described. A highly coherent light emitted from a light source is used to illuminate a surface and produces scattered lights. The scattered lights pass through a light restrictive element and the diffracted lights produced by this restrictive element interfere with one another to generate a speckle pattern. An image sensor is then used to pick up the speckle pattern to form a speckle image. Therefore, the effects of diffraction and interference and a light restrictive element to enlarge the speckle size and reduce the variation of the speckle pattern during the movement of the imaging device are utilized, so that the speckle pattern can be clearly identified in the image. As a result, the method and device for capturing speckles are fairly stable and sensitive.Type: ApplicationFiled: December 15, 2005Publication date: June 21, 2007Inventors: Yi-Yuh Hwang, Ming Chen, Mau-Ran Wang, Wen-Chen Huang, Shin-I Ma

Publication number: 20070064983Abstract: The present invention discloses a method for automatically detecting a nasal tumor from the MR (magnetic resonance) images. First, the pixels that have specific trends and are affected by contrast agents with specific level will be filtered according to the developing coefficient and control coefficient of grey prediction. Then the tumor area would be detected by using Fuzzy C-means clustering technique to distinguish the differences between normal tissue and tumor. Owing to the work of grey prediction, calculation in the Fuzzy C-means clustering technique can be dramatically reduced and the result of tumor detection is enhanced.Type: ApplicationFiled: September 16, 2005Publication date: March 22, 2007Inventors: Wen-Chen Huang, Chun-Pin Chang
