Abstract:
PURPOSE: A music information customizing method and apparatus are provided to improve user convenience by offering a customized service reflecting user's feeling. CONSTITUTION: A receiving unit(101) receives musical inclination evaluation of a user to the currently reproduced music from the user. A tracking unit(102) traces the expression coordinates of the user's musical inclination using the musical inclination evaluation and ages the expression coordinates to trace the final expression coordinates of the user's musical inclination. A searching unit(104) searches a playlist corresponding to the user's musical inclination.
Abstract:
PURPOSE: A digital contents forensic marking apparatus and a method thereof are provided to remove delay time due to insertion of forensic mark and to rapidly supply a service. CONSTITUTION: A forensic marking unit(130) generates first and second content which insert first and second binary forensic marks. If a content service request is generated, the forensic marking unit combines first and second contents based on user information which requests the content service. Content database(150) stores the first and the second content.
Abstract:
본 발명은 장면 전환 검출 기술에 관한 것으로, 디지털 영상기기에서 사용되는 디지털 비디오 데이터를 복호화하여 하나의 코덱 또는 압축되지 않은 데이터로 통일하고, 복호화된 디지털 비디오 데이터에 대한 정규화를 수행하여 정규화된 프레임에서 장면 전환 여부를 검출한다. 이러한 장면 전환 여부 검출을 위해 정규화된 프레임에 대한 최적 모드를 결정하여 결정된 최적 모드들로 장면 전환을 검출하기 위한 비율을 계산하고, 계산된 모드 비율에 발생할 수 있는 오류 제거 후 해당 프레임에 대한 장면 전환 여부를 검출하는 것을 특징으로 한다. 본 발명에 의하면, 디지털 비디오의 공간적 및 시간적 중복성을 이용하여 디지털 비디오의 장면 전환 검출 성능을 향상시킬 수 있으며, 비디오에 따라 발생할 수 있는 다양한 국부적인 오류에 대해서도 유연하게 대처할 수 있다. 또한 장면 전환 검출 시스템의 특징 및 디지털 비디오의 성격에 따라 장면 전환 검출 장치를 결정하여 보다 나은 장면 전환 검출율을 제공할 수 있다. 디지털 비디오, 장면 전환, 장면 전환 검출기
Abstract:
PURPOSE: A fingerprint extracting method of publications, a device thereof, a publication identifying system using a fingerprint, and a publication identifying method using the fingerprint are provided to connect a fingerprint extracted from an original publication with metadata information and extract a fingerprint of an inquiry publication, thereby identifying information of an unknown publication. CONSTITUTION: An image-text converting unit(730) converts an input image type electronic document into a text type electronic document. A text extracting unit(750) extracts a text from the text type electronic document. A fingerprint extracting unit extracts a text fingerprint from the text. An image preprocessing unit(720) eliminates a noise from the text type electronic document, divides pages, and adjusts image rotation/angle. The fingerprint extracting unit extracts an image fingerprint from a preprocessed image which is provided from the image preprocessing unit.

Abstract:
PURPOSE: A video identification method and apparatus using the symmetric information of a hierarchical image block are provided to simplify the identification information of a digital video. CONSTITUTION: A frame rate converting unit(121) converts the frame rate of an inputted video signal into a predetermined value. A black and white scale converting unit(123) performs the black and white scale conversion of the video signal. A frame size normalizing unit(125) normalizes the frame size of the video signal to a predetermined size. A block feature extracting unit(127) divides an image into layer blocks. The block feature extracting unit extracts the symmetry information of each block.
Abstract:
PURPOSE: An image identification apparatus and method are provided to offer the effectiveness of storage capacity and tenacity for geometrical distortion. CONSTITUTION: Using a specific variable and a user input signal, a resolution normalization unit(100) normalizes static images to a specific size. A feature area extractor(200) extracts an intrinsic specific area from the normalized image of the resolution normalization unit. Using the intrinsic specific area extracted through the feature area extractor, a global histogram generator(300) acquires an image identifier.
