The image templates were firstly processed by Generalized Fuzzy Operator(GFO), then the edge characteristic points obtained by GFS were used as the match points to put some pieces of images together.
应用这些特征点进行眼底图象的配准，最终将各部分眼底图象拼接成一较完整的图象。
In the same geometrical direction of the sample to be registered and its neighboring images, some edge points are first detected as the characteristic points with directional edge-detection operator.
在样本和待配准图像相同几何方向上，先以方向边缘点检测算子检测目标区的数个边缘点作为特征点。
