Abstract: Disclosed are an apparatus and method for extracting a skin area to block a harmful image. The apparatus includes an image extraction unit, a skin sample area extraction unit, a background sample area extraction unit, a probability density function computation unit, and a skin area extraction unit. The image extraction unit extracts an image from image media. The skin sample area extraction unit extracts a skin sample area of the image based on prior information. The background sample area extraction unit extracts a background sample area of the image based on the prior information. The probability density function computation unit calculates the probability density functions of the skin sample area and the background sample area. The skin area extraction unit extracts a skin area from the image based on the probability density function of the skin sample area and the probability density function of the background sample area.
