Chapter 6

1. OpenCV function to print pixel intensity at location(200,200) of any color image on the console is as follows:

cv::Mat h_img2 = cv::imread("images/autumn.tif",1);
cv::Vec3b intensity1 = h_img1.at<cv::Vec3b>(cv::Point(200, 200));
std::cout<<"Pixel Intensity of color Image at (200,200) is:" << intensity1 << std::endl;

2. OpenCV function to resize an image to (300,200) pixels using bilinear Interpolation method is as follows:

cv::cuda::resize(d_img1,d_result1,cv::Size(300, 200), cv::INTER_LINEAR);

3. OpenCV function to upsample an image by 2 using AREA interpolation is as follows:

int width= d_img1.cols;
int height = d_img1.size().height;
cv::cuda::resize(d_img1,d_result2,cv::Size(2*width, 2*height), cv::INTER_AREA); 

4. False. Blurring increases as we increase the size of a filter.
5. False. The median filter can't remove Gaussian...
