本程序利用不变矩实现了仿射变换的功能，感觉效果不错。-This procedure using invariant moment realized the affine transform function, feeling good results.

ASIFT算法的一个demo.相比SIFT,ASIFT通过对图像进行仿射变换,模型角度的变换,使得更具有仿射不变性.-ASIFT algorithm is a demo. Compared to the SIFT, ASIFT through the image affine transformation, perspective transformation model, making it more with the affine invariant.

基于SURF的仿射变换识别源代码，包括提取灰度图像的尺度不变特征（SIFT特征）-SURF-based affine transformation recognition source code, including the extraction of grayscale images scale invariant feature (SIFT features)

以具体的实例讲解了halcon中的几何变换和仿射变换，这在OCR识别中经常遇到的方法(The geometric transformation and affine transformation in halcon are explained in concrete examples, which are often encountered in OCR recognition.)
