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-…

Description There is a number of disjoint vertical line segments in the plane. We say that two segments are horizontally visible if they can be connected by a horizontal line segment that does not have any common points with other vertical segments.…

前言 在opencv中cv::flip函数用于图像翻转和镜像变换. 具体调用形式 void cv::flip( cv::InputArray src, // 输入图像 cv::OutputArray dst, // 输出 // >0: 沿y-轴翻转, 0: 沿x-轴翻转, <0: x.y轴同时翻转 ); Flips a 2D array around vertical, horizontal, or both axes. 测试代码 void flip_test() { cv::Mat imag…

题意   在坐标系中有n条平行于y轴的线段  当一条线段与还有一条线段之间能够连一条平行与x轴的线不与其他线段相交  就视为它们是可见的  问有多少组三条线段两两相互可见 先把全部线段存下来  并按x坐标排序  线段树记录相应区间从右往左当前可见的线段编号(1...n)  超过一条就为0  然后从左往右对每条线段  先查询左边哪些线段和它是可见的  把可见关系存到数组中  然后把这条线段相应区间的最右端可见编号更新为这条线段的编号  最后暴力统计有多少组即可了 #include <cstdio>…

OpenCV中实现图像翻转的函数flip,公式为: 目前fbc_cv库中也实现了flip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flip.hpp: // fbc_cv is free software and uses the same licence as OpenCV // Email: fengbingchun@163.com #ifndef FBC_CV_FLIP_HPP_ #define FBC_CV_FLIP_HPP_…
