  • Publication number: 20120027217
    Abstract: An apparatus and method for merging acoustic object information to provide an Augmented Reality (AR) service in which real images are merged with sounds. The acoustic object information merging apparatus includes an acoustic objectization unit, an acoustic object information creator and a merging unit. The method classifies sounds received in a microphone array to identify an object corresponding to the received sound. If there is a failure to identify an object for each sound, then a band-pass filter is applied to secondarily classify the received sounds. Acoustic object information is created and merged with a captured image or recorded sound. The acoustic object information may include additional information about the object identified as corresponding to the received sound.

  • Publication number: 20090172404
    Abstract: 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.
