Subline matching method based on binary system small wave transform is proposed, which expliots the character that the model maximum point of spline binary small wave transform coefficient at different scales can provide position information of signal's fast changing point.

In this time, we can recognize the number image depending on the location of the end-point. If the y-coordinate of the end-point is bigger than half of the height of the number image, the recognized result is 6. Else the result of recognition is 9. Then if there are two end-points and there is no trifurcate point, the possible recognition result of the number image is 2, 3, 5 or 7. Here, we need to recognize the number image by dint of the end-point directions and locations.

最后，我们根据特征提取的结果进行分类识别，如果没有端点、没有三叉点，则识别结果为0；如果无端点，两个三叉点，则识别结果为8；如果只有一个端点、一个三叉点，则识别结果可能为6或9，这时只需考虑端点的位置，即可将6和9区分开来；如果有两个端点、无三叉点，则识别结果可能为2、3、5、7，这时需要加入端点的位置和方向辅助判断。
