20080232468 | METHOD AND APPARATUS FOR ADAPTIVE GOP STRUCTURE DETERMINATION - A video encoder, determining a Group of Picture (GOP) structure and a method thereof. The video encoder comprises an input frame buffer, an I-frame module and a P-frame module. The input frame buffer receives and stores input frames. The I-frame module coupled to the input frame buffer identifies an I-frame based on a correlation between two consecutive input frames to obtain the GOP size. The P-frame module coupled to the input frame buffer and the I-frame module, determines P-frames in the GOP having the GOP size based on the GOP rate. | 09-25-2008 |
20080253675 | IMAGE PROCESSING METHOD AND RELATED PARTIAL PSF ESTIMATION METHOD THEREOF - An image processing method includes (a) performing edge detection to an image to obtain a plurality of the edge pixels of the image; (b) performing partial PSF estimation to each of the edge pixels to generate a plurality of partial PSF estimation results; and (c) generating a PSF estimation result according to the partial PSF estimation results. | 10-16-2008 |
20080292273 | Uniform Program Indexing Method with Simple and Robust Audio Feature and Related Enhancing Methods - Simple, computational efficient, and robust audio features are applied in a uniform program indexing method for picking up video segments relating to highlight plays in a recorded program worthy of being reviewed. By focusing on certain frequencies in an audio sequence of the program, a computational complexity of the uniform program indexing method is significantly decreased. With the aid of MFCC coefficients and a DFBE coefficient generated from the MFCC coefficients, audio patterns may be utilized for differentiating exciting events in the program from other unnecessary information. Scores corresponding to various audio segments are regarded as standards for picking up video segments in the program worthy of being chosen in a recorded highlight collection. Some low-level-feature parameters, some video segments having highlight-related visual characteristics, and a re-ranking procedure are utilized for enhancing precision of the scores for providing video segments worthy of being reviewed. | 11-27-2008 |
20090122189 | Method of Identifying Target Synchronization Point Pair through Scan-line Image Matching Scheme - A method of identifying a target synchronization point pair including a source synchronization point corresponding to a source end and a destination synchronization point corresponding to a destination end is provided. The method includes receiving a source scan-line image corresponding to a first video source from the source end; selecting at least a comparing frame out of the source scan-line image; providing a destination scan-line image corresponding to a second video source at the destination end; and determining the target synchronization point pair by comparing the comparing frame and the destination scan-line image. | 05-14-2009 |
