摘　　要：提出了一种基于图像分割和仿射变换的真实感枫树绘制方法。该方法采用图像分割技术和形态学方法由真实枫叶获取枫叶的二值化掩模,然后在掩模的作用下,采用仿射变换在枫树枝上绘制不同形状和大小的具有真实纹理的枫叶。实验表明,采用该方法绘制的枫树枝,不仅很好地表现了枫树叶的形状,还保留了枫树叶的真实纹理。该方法可以推广到绘制任何真实感的植物。On the basis of image segmentation and affine transformations,a method of drawing the realistic maple tree is proposed.The whole process of the method can be described as follows： by using the technology of image segmentation and image morphology,we could obtain the binary image mask of the maple leaf which has the precisely one-bit-width boundary;then the affine transformations are performed on the maple leaf image so that we can draw the maple leaf on the different positions of the branches and change the size and the rotation angle of it.The experiments show that the maple branches which are drawn with our method not only have the same shape with the true ones but also conserve the real texture of the leaf.As a result,the method can be extended to draw other realistic plants.
