OpenCV imwrite() not saving image

Question

I am trying to save an image from OpenCV on my mac and I am using the following code and so far it has not been working.

cv::imwrite(\"/Users/nickporter/Desk         


        

Answer 1

I've just had a similar problem, loading in a jpg and trying to save it back as a jpg. Added this code and it seem to be fine now.

vector compression_params;
compression_params.push_back(CV_IMWRITE_JPEG_QUALITY);
compression_params.push_back(100);

And you need to include the param in your writefile.

cv::imwrite("/Users/nickporter/Desktop/Gray_Image.jpg", cvImage, compression_params);
