Method for dominant color setting of video region and data structure and method of confidence measure extraction
First Claim
1. A method for searching multimedia data in a multimedia device using a region dominant color descriptor, the method comprising:
- extracting 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;
comparing the extracted region dominant color descriptor with at least one stored region dominant color descriptor;
searching multimedia data based on the coherent degree;
obtaining a searched multimedia data for sorting the searched multimedia data; and
sorting the searched multimedia data based on an input indicating a sorting of the searched multimedia data, wherein the region dominant color descriptor further includes an accuracy of the region dominant color indicating a degree of confidence of the region dominant color descriptor.

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.
