Affine Transformation02
- The transformation parameters are specified by the user by editing the values of the rotation, scale (x and y), and shear (x and y). The translation is not icluded because it can be easily (normalized or) removed from the image by subtracting t
第12章 图像的纹理分析方法
- 图像的纹理分析方法(从图像、图形融合的思想出发 ，介绍了基于图像分析的表面形状恢复及纹理 三维特征获取方法，并将其应用于图形建模和纹理映射．首先利用不同视点下的遮挡 边缘序列，并结合其它视觉信息的分析，获取了表面点的三维几何坐标，实现了基于 图像分析的表面形状绘制．接着利用阴影分析方法，提取纹理图像的表面起伏特征， 将该特征结合像素点的颜色属性，进行图形纹理映射，实现了基于图像特征分析的图 形纹理生成．实验结果证明了图像、图形融合思路的可行性和有效性及图像、图形融 合方法

hough(vc)
- Hough变换最先是由Paul Hough在1962年提出的， 它所实现的是一种从图像空间到参数空间的映射关系,其主要优点就是检测几何形状的能力较少受到几何形状中间断点的干扰 ， 而且不需要预先组合或连接边缘点， 可以广泛应用于纤维、 孔径等自动检测中-Hough transform is the first by Paul Hough in 1962, and it is a realization from the image space to parameter space of the
