  • Patent number: 7321684
    Abstract: A method is provided for setting a dominant color using a spatial coherency in order to improve performance of an image search function. The method includes describing an image region based on several dominant colors, a frequency of each dominant color, and a spatial coherency (SC) of the dominant color. In the method, the spatial coherency is non-uniformly quantized based on a predetermined threshold. For example, the spatial coherency (SC) may be ranged from 0 to 1 and the threshold may be set to 0.70.

  • Patent number: 7127735
    Abstract: A video-on-demand (VOD) system and method which efficiently enables a user to resume viewing of a video program from an interrupted position is disclosed. The present invention allows the user to resume viewing of a video program even if the user requests a resumption of the interrupted video program several times or through different video servers. Particularly, the video viewing characteristic information of a user terminal is not managed by a video server of the VOD system, but is managed by the user terminal. Accordingly, when a user interrupts viewing of a video program, the video server transmits to the user terminal user profile information which includes the characteristic information related to the viewing of the video program. Thereafter, if the user requests resumption of the interrupted video program using the user profile information, the video server re-transmits the video program from the interrupted position of the video program.

  • Patent number: 7085402
    Abstract: A method of detecting a specific object in an image signal both efficiently and accurately is disclosed. According to the method, an object is first detected from an image or frame using a general feature of the object and in the following image or frame, the object is detected using an object-dependant feature. Also, when detecting a plurality of objects or portions of the object, a full color range of the specific object is determined, and color range sections of the full color range is used to detect the object.

  • Patent number: 7027644
    Abstract: The present invention relates to an image search method capable of expressing one color feature related to a spatial color feature of a still image based on a multilevel image grid and similarity-based searching images using the thusly expressed multilevel image grid. In the present invention, hierarchical grids of different levels are generated with respect to one feature for thereby obtaining a data structure in which each cell corresponding to the grid is expressed based on a reliability on a region representative color and the region representative color, so that it is possible to fast and accurately search images with respect to a user's content-based query based on a cell matching of the same level as two image grids and different levels or a color local matching of the grid match.

  • Patent number: 7003518
    Abstract: Disclosed is a multimedia searching method and apparatus that can achieve a high performance and provide a interoperability by defining a histogram using uniformly quantized bin values as a standard histogram, and a comparative search can be performed using a search histogram having non-uniformly-quantized bin values based on the standard histogram. The non-uniformly quantized bin values of the search histogram can be determined for each application by non-uniformly combining the uniformly-quantized bin values. According to a method, the histogram is defined as a standard histogram, and a comparative search is performed by converting the standard histogram. Further, a standard histogram obtained by uniformly quantizing a given color space can be converted into a search histogram (e.g., determined for a certain application) by non-uniformly combining the bins obtained by uniformly quantizing the color space into the N partial regions.
