Answer 1

The following function can be dropped into your code to support writing out jpg images for debugging purposes.

You just need to pass in an image and a filename for it. In the function, specify a path you wish to write to & have permission to do so with.

void imageWrite(const cv::Mat &image, const std::string filename)
{
    // Support for writing JPG
    vector compression_params;
    compression_params.push_back( CV_IMWRITE_JPEG_QUALITY );
    compression_params.push_back( 100 );

    // This writes to the specified path
    std::string path = "/path/you/provide/" + filename + ".jpg";

    cv::imwrite(path, image, compression_params);
}
