Method for dominant color setting of video region and data structure and method of confidence measure extraction
First Claim
1. A content-based retrieval method in a multimedia device, the method comprising:
- searching in the multimedia device a specific region in a media object by using a dominant color descriptor, wherein the dominant color descriptor includes information quantifying a number of dominant colors with respect to a region of interest in visual data, information on at least one expressed dominant color, a frequency with which the dominant color appears in the region, and a coherency value which represents a concentration degree of pixels of a color with respect to the dominant color.

Abstract
A method for a dominant color setting of a video region and a data structure and a method of a confidence measure extraction are disclosed. The video region dominant color setting method is characterized in that a region dominant color descriptor is expressed by the number of dominant colors with respect to a certain region, a dominant color expressed, a frequency that the dominant color appears, and an accuracy of a color value representing the region in a region dominant color based on various region dominant color extraction methods, for thereby expressing a region dominant color using a plurality of colors with respect to a region dominant color value and a confidence value of a region dominant color information based on various region dominant color feature extracting methods.

13. A method for searching visual data using dominant color in a multimedia device, the method comprising:
-
searching in the multimedia device a specific region of interest from a media object by using a dominant color descriptor for the region, said descriptor including; a) information quantifying a number of dominant colors (N) selected for extraction from the region, where N≧
1;b) information indicative of color values for the dominant colors in the region; c) information indicative of frequencies with which the N dominant colors appear in the region; and d) a coherency value which represents a concentration degree of pixels of a color with respect to the dominant color. - View Dependent Claims (14, 15, 16)
