基于opencv-python的身份证识别（KNN与OCR两种算法）

本文是学习opencv之初的一个阶段性小任务，主要做练习使用，并没有过多的追求准确率和高可用性，比如对输入身份证照片有要求，必须是完全的身份证照片，不能有背景，如需改进，可以通过增加轮廓检测和透视变换来裁剪出身份证照片；还有对身份证号区域的检测，采用的是先裁剪出一个固定大...

【转】OpenCV实现KNN算法

K Nearest Neighbors 这个算法首先贮藏所有的训练样本，然后通过分析（包括选举，计算加权和等方式）一个新样本周围K个最近邻以给出该样本的相应值。这种方法有时候被称作“基于样本的学习”，即为了预测，我们对于给定的输入搜索最近的已知其相应的特征向量。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24...
