Face detecting method depending on image

Abstract

The present invention is provided a face detecting method depending on image that includes a step of obtaining a color group mainly distributed in a given image; a step of designating a color group corresponding to a human color in the obtained color groups; and a step of segmenting a portion composed with pixels corresponding to color group of a human color. Here, a step of cognizing a face may be further included. Further, the step of obtaining mainly distributed color groups comprises a step of composing a color histogram of the image; a step of obtaining an bin (bmax) having the maximum bin value of the color histogram; a step of measuring similarity between a representative color value of the bmax and a representative color value of other respective bins; a step of designating the range of color of a main color by using bins, where measured similarity is below a critical value, and bmax; and a step of designating a representative color of the main color. Also, a step of detecting bin corresponding to the extracted main color from the color histogram, a step of calculating the maximum bin for the rest of bins, and a step of designating a main color group in addition when the maximum bin is above a critical value are further comprised.
