Method for dominant color setting of video region and data structure and method of confidence measure extraction
First Claim
1. A confidence measure extraction method of a dominant color of an image region, comprising:
- obtaining a number of color pixels corresponding to each dominant color and a coherence value corresponding to each dominant color;
multiplying the coherence value by a value corresponding to the number of color pixels with respect to each dominant color, adding the multiplied values with respect to all of the region dominant colors; and
dividing the thusly added multiplied values by a region size and extracting a confidence value descriptive of dominant colors in the image region.

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.
