摘　　要：在艺术效果仿真算法中,中国水墨画的仿真是一个有挑战性的研究课题。为实现山水风景图像的水墨效果仿真生成,提出基于灰度层反相叠加的水墨画仿真算法。算法首先运用直方图规定化方法实现图像的8阶灰度转换,并将各灰度区域分解成层,在真实墨迹特征分析的基础上对各层"墨区"进行墨迹仿真,最后通过灰度层的反相叠加实现由远及近、由浅入深的水墨画逐层仿真模拟。实验证明,该方法生成的风景水墨图具备了水墨画应有的形态和特征,取得了一定的仿真效果。Among the algorithms of artistic effect simulation, the simulation of Chinese ink wash painting is a challenging task.To realise the simulative generation of ink wash effect of the ink wash paintings of landscape, we present a simulation algorithm for ink wash painting which is based on inversely overlaying the gray layers.The algorithm applies the histogram specification method to realise the 8-order grayscale conversion at first, and decomposes each gray region into layers;then it makes ink marks simulation of each“ink zone” layer based on analysing the characteristics of true ink marks;at last it realises the simulation of the ink wash painting in the way of imitating layer by layer from far and near and approaching progressively through the inverse overlay of the grayscale layers.Experiments prove that the ink wash paintings of landscape generated with this method possess the due pattern and the characteristics of the ink wash painting, thus achieves certain simulation effect.
