I am not sure why I cannot read an image by using imread function and the details about my code are as the following. Please help me. Thank you, everybody!
include <iostream>
include "opencv2/imgproc/imgproc.hpp"
include "opencv2/highgui/highgui.hpp"
include "opencv2/core/core.hpp"
int main(int argc, const char * argv[]){
cv::Mat scrImage = cv::imread("/Users/zsk/Downloads/zsk.JPEG", CV_LOAD_IMAGE_COLOR);
if(scrImage.empty())
{
std::cout << "something wrong" << std::endl;
return -1;
}
cv::Mat scrGray;
cv::cvtColor(scrImage, scrGray, CV_RGB2GRAY);
cv::imshow("scrGray", scrGray);
cv::Mat blurDstImage;
blur(scrGray, blurDstImage, cv::Size(5, 5), cv::Point(-1, 1));
cv::imshow("blurDstImage", blurDstImage);
cv::imwrite("/Users/zsk/Downloads/blurgirl.jpg", blurDstImage);
cv::waitKey(0);
return 0;}
The build information is as the following.
