    摘要： 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.

    摘要： The present invention relates to a system for scene change detection including a decoder decoding input digital video data into video data compressed by a single codec or uncompressed video data in a codec-independent format, a normalizer normalizing the video data decoded by the decoder in a temporally and spatially uniform format, and a scene change detector computing a mode ratio for each frame of the normalized video data through a mode determination, and determining, when a frame has a mode ratio higher than a preset threshold value, that a scene change has occurred at the frame. The decoder decodes video data compression-coded by various video codecs into uncompressed video frames.
