This paper presents a new Gaussian filtering algorithm,namely EPGF,for colour images.The proposed method utilises the human visual mechanism of colour detail blindness and the character of simultaneous contrast,and then decides the Gaussian mask jointly according to the colour difference and the location between adjacent pixels.The proposed method can maintain the edges between areas unchanged while smooth the image inside area.Different filtered results are provided with their subjective and objective contrasts.Experimental results show the validity of the proposed method.
