20080313152 | Real-Time Digital Video Identification System and Method Using Scene Information - Provided is a real-time digital video identification system for searching and identifying a digital video in real-time by effectively constructing a database using a scene length of a digital video, and a method thereof. The system includes: a scene information extractor for receiving a digital video, extracting a difference between frames of the received digital video, detecting a scene change portion and calculating a scene length using the portions; a digital video database for storing a plurality of digital videos and scene lengths corresponding to the stored digital videos; and a digital video comparator for receiving the calculated scene length from the scene information extractor, sending a query to the digital video database and comparing the received scene length with the response of the query from the digital database. | 12-18-2008 |
20090125310 | APPARATUS AND METHOD FOR INSERTING/EXTRACTING CAPTURING RESISTANT AUDIO WATERMARK BASED ON DISCRETE WAVELET TRANSFORM, AUDIO RIGHTS PROTECTION SYSTEM USING THE SAME - An apparatus and method for embedding and extracting a capturing-resistant audio watermark based on discrete wavelet transform, and a copyright management system using the same are provided. The apparatus for embedding a wavelet based audio watermark includes: a framing unit for dividing an input audio signal into small signals with a regular length; a discrete wavelet transform unit for calculating an mean value of wavelet coefficients by transforming the small signals based on a discrete wavelet transform; and an embedding unit for changing the calculated mean value according to a watermark where a synchronization signal is inserted and inserting the watermark into the audio signal. | 05-14-2009 |
20090172404 | Method and Apparatus for Hybrid Watermarking - A hybrid watermark insertion method includes the steps of dividing the digital image into a low frequency region and a high frequency region using an edge map of the digital image; inserting a watermark into the low frequency region of the image by employing a watermarking method using a human visual system (HVS); and inserting the watermark into the high frequency region of the image by employing a quantization index modulation (QIM) method. A hybrid watermark extraction method includes the steps of estimating a reference value used when inserting a watermark, and searching a maximum value of correlation coefficients in an image of the watermark image while changing the estimated reference value within a designated range, to thereby find out the watermark insertion method. Accordingly, the watermark insertion method can be easily identified, thereby enabling the watermark extraction in a more readily manner. | 07-02-2009 |
20100063978 | APPARATUS AND METHOD FOR INSERTING/EXTRACTING NONBLIND WATERMARK USING FEATURES OF DIGITAL MEDIA DATA - An apparatus and method for inserting/extracting a nonblind watermark using features of digital media data are provided. The apparatus and method inserts a watermark adaptively using watermark-related information determined by analyzing the characteristics of digital media data, also extracts features of the digital media data, automatically searches original media data corresponding to the features, and simultaneously and efficiently extracts a watermark using watermark-related information. Therefore, When the watermark is extracted, the original media data can be searched automatically. | 03-11-2010 |
