OpenCV中的transpose函数实现图像转置,公式为: 目前fbc_cv库中也实现了transpose函数,支持多通道,uchar和float两种数据类型,经测试,与OpenCV3.1结果完全一致. 实现代码transpose.hpp: // fbc_cv is free software and uses the same licence as OpenCV // Email: fengbingchun@163.com #ifndef FBC_CV_TRANSPOSE_HPP_ #def
The OpenCV GPU module is a set of classes and functions to utilize GPU computational capabilities. It is implemented using NVIDIA* CUDA* Runtime API and supports only NVIDIA GPUs. 1. getCudaEnableDeviceCount:returns the number of installed CUDA-
在Mat矩阵类的成员函数中copyTo(roi , mask)函数是非常有用的一个函数,尤其是后面的mask可以实现蒙版的功能,我们用几个实例来说明它的作用.我们要注意mask的数据类型,必须是CV_8U,且通道数或者是1,或者与roi一致. 首先我们令mask为尺寸与roi一致的1矩阵: int main() { Mat img1=imread(); Mat img2=imread(); imshow("initial img1",img1); Mat roi=img1(Rect(,

Use the OpenCV function :copy_make_border:`copyMakeBorder <>` to set the borders (extra padding to your image).The explanation below belongs to the book Learning OpenCV by Bradski and Kaehler. In our previous tutorial we learned to use convolution t
