  • Publication number: 20020181768
    Abstract: A method for designating a local representative color value and automatically determining image searching algorithm for a color based image searching system is disclosed. A method for designating a local representative color values generally includes the steps of dividing a color image area; and obtaining a color histogram for each block, obtaining a color group from hue histograms of each block, or obtaining a maximum color group value to designate the representative color value. Also, a method determining a search algorithm generally includes the steps of detecting the number of color blocks CB having color information from the blocked information of a reference image; comparing the number of the color blocks with a determined reference value and assigning different weights to at least two search algorithm according to the comparison results; and performing a comparison search of an image by the search algorithm based on the determined weight.

  • Publication number: 20020094124
    Abstract: The present invention discloses a method for setting a dominant color using a spatial coherency in order to improve performance of an image search function, 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 according to the present invention, the spatial coherency is non-uniformly quantized based on a predetermined threshold. According to one embodiment of the present invention, the spatial coherency (SC) is ranged from 0 to 1 and the threshold is set to 0.70.

  • Patent number: 6310969
    Abstract: A color space structure and quantizing method is disclosed. Upon conversion from the RGB color space into HSV color space, a difference value S′ (S′=max−min) is obtained by varying the maximum value of the saturation S in accordance with the value V resulting in a HS′V color space where the difference value S′ forms one axis of the color coordinate, such that all of color areas are evenly distributed and the variation of color is uniformly displayed.

  • Publication number: 20010028739
    Abstract: Disclosed is a content-based multimedia data retrieval method. The method according to the present invention comprises the steps of extracting color distortion information from multimedia data, setting weight of color-based descriptors on the basis of the extracted color distortion information, and extracting a distortion sensitivity by differently applying the weight according to the color distortion information. The method according to the present invention can improve a multimedia data retrieval performance and solve a problem of color distortion due to a different illumination or characteristics of a device.

  • Publication number: 20010005426
    Abstract: The present invention relates to a color space quantization descriptor structure for performing quantization of a color space in order to search a multimedia based on contents when multimedia feature information is color information, particularly when the multimedia feature information is the color information and the search is about a moving image or a still image, the color space quantization descriptor structure according to the present invention has a tree structure divided into a plurality steps of superior color spaces and subordinate color spaces, and the tree structure recurrently comprises a plurality of subordinate color spaces. Accordingly, the present invention can improve performace of a still image and a moving image search apparatus, perform the quantization of a n dimensional color space such as a H, S, V, RGB, HMMD color space etc., and perform the different step quantization corresponding to each feature.

  • Patent number: 6129845
    Abstract: A photo-oxidation device of a water treatment system photo-oxidizes organic material, in particular, aromatic organic material, in the water to facilitate its removal from the water. The photo-oxidation device includes a UV lamp, a flow channel in which the UV lamp is disposed, and a catalyst of an oxidation reaction between an organic material and the UV radiation emitted by the UV lamp. The UV radiation emitted from the UV lamp illuminates the flow channel while the water passes through the flow channel. The catalyst, on the other hand, is fixed to an inner wall of the flow channel to foster the oxidation of the organic material by the UV radiation. The water treatment system in which the photo-oxidation device is incorporated, includes a pre-treatment unit having particle filters, a first treatment section, and a second treatment section.
