| description | The present invention suggests an apparatus and a method for determining a representative color of an iris. The method for determining a representative color of an iris comprises the steps of: extracting an iris area from an eyeball image; quantizing a pixel value of each pixel in the iris area; converting the quantized pixel values into a color space component value according to color coordinates different from color coordinates representing the pixel value, and categorizing the converted color space component value according to a predetermined method; and determining an iris representative color by using one or more component values of the categorized color space component values.
본 발명은 홍채의 대표색을 결정하는 장치 및 방법을 제안한다. 홍채의 대표색을 결정하는 방법은 안구 이미지에서 홍채 영역을 추출하는단계; 상기 홍채 영역의 각 픽셀의 화소값을 양자화하는 단계; 상기 양자화된 화소값들을 상기 화소값을 나타내는 표색계와는 다른 표색계에 따른 색공간 성분값으로 변환하고, 상기 변환된 색공간 성분값을 미리 결정된 방법에 따라 범주화하는 단계; 상기 범주화된 색공간 성분값중 하나 이상의 성분값을 이용하여 홍채 대표색을 결정하는 단계; 를 포함한다. |
