2 打开VS2015选择文件,然后新建项目,选择新建一个Win32控制台应用程序,并选择空项目并在源文件中添加一个名为resize的CPP文件 3 在该resize.cpp文件中输入一下代码#include "cv.h" // OpenCV 文件头#include "highgui.h"#include "cvaux.h"#include "cxcore.h"#include "opencv2/opencv.hpp"#include ...

OpenCV这么简单为啥不学——1.3、图像缩放resize函数 前言 计算机视觉市场巨大而且持续增长,且这方面没有标准API,如今的计算机视觉软件大概有以下三种: 1、研究代码(慢,不稳定,独立并与其他库不兼容) 2、耗费很高的商业化工具(比如Halcon, MATLAB+Simulink) ...
OpenCV官方说明:注意红色方框那句话:OpenCV: Geometric Image Transformations To shrink an image, it will generally look best with cv::INTER_AREA interpolation, whereas to enlarge an image, it will generally look best with cv::INTER_CUBIC (slow) or cv::INTER_LINEAR (faster but still looks OK)...
OpenCV中使⽤cvResize函数或resize函数进⾏图象放缩//cvResize函数原型 void cvResize( const CvArr* src, CvArr* dst, int interpolation=CV_INTER_LINEAR );src:输⼊图像.(IplImage)dst:输出图像.(IplImage)interpolation:差值⽅法:CV_INTER_NN - 最近邻差值 CV_INTER_LINEAR - 双线性差值 (缺省使...
3)INTER_AREA - 基于局部像素的重采样(resampling using pixel area relation)。对于图像抽取(image decimation)来说,这可能是一个更好的方法。但如果是放大图像时,它和最近邻法的效果类似。 4)INTER_CUBIC - 基于4x4像素邻域的3次插值法 5)INTER_LANCZOS4 - 基于8x8像素邻域的Lanczos插值 ...
