样板主要分为4步:a、包含Python的头文件;b、为每个模块的每一个函数增加一个型如PyObject* Module_func()的包装函数;c、为每个模块增加一个型如PyMethodDef ModuleMethods[]的数组;d、增加模块初始化函数void initModule()。 #include <stdio.h> #include <stdlib.h> #include <string.h> int fac(int n)...
2、nbytes、size、itemsize属性 在OpenCV-Python对外接口里图像用numpy数组表示,所以numpy数据的属性同样适用于OpenCV-Python中图像的属性,详情可参考NumPy数组的属性和常用创建方法。 下面的例子中仍是通过3种不同方式获取图像后对比各个属性的例子: importnumpyasnp importcv2 print('VX公众号: 桔子code / juzicode.c...
