METHOD FOR DOMINANT COLOR SETTING OF VIDEO REGION AND DATA STRUCTURE AND METHOD OF CONFIDENCE MEASURE EXTRACTION
First Claim
1. A system for searching multimedia data in a multimedia device using a region dominant color descriptor, the system being configured to:
- extract a region dominant color descriptor from query multimedia data, the region dominant color descriptor including a coherent degree of pixels corresponding to a dominant color;
compare the extracted region dominant color descriptor with at least one stored region dominant color descriptor;
search multimedia data based on the coherent degree;
obtain an accuracy of the searched multimedia data; and
output the accuracy of the searched multimedia data.

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.
