| 摘 要： | 基于彩色图像中的色调信息不易受到镜面反射干扰这一事实,文中提出基于色调约束的镜面反射分离算法.首先,利用图像的色调信息对图像进行聚类.再计算像素色度与照明色度的距离,求得漫反射和镜面反射的融合系数.同时,为了让像素聚类免受噪声干扰,对融合系数执行双边滤波操作.最后,根据已求得的融合系数,得到消除镜面反射后的漫反射图像.实验表明,文中算法能在有效去除镜面反射的同时保留图像的细节与边缘信息,在对自然高光图像的处理中也取得较佳的视觉效果. |

| Abstract: | The hue information in color images is not easily susceptible to inference from specular reflection. Grounded on this fact, an effective algorithm of specular reflection separation with hue constraint is proposed. Images are clustered by its hue information. The fusion coefficient of diffuse reflection and specular reflection is obtained by calculating the pixel chromaticity and the illumination chromaticity. The bilateral filter is conducted on fusion coefficients to eliminate the noise impact. A diffuse reflection image is acquired according to the calculated specular reflection coefficients. The experimental results show that the proposed method removes specular reflection effectively with the details and edge information of the image retained and it achieves satisfactory visual effects in processing natural highlight pictures without ground truth. |
