#take the base64_decode from https://renenyffenegger.ch/notes/development/Base64/Encoding-and-decoding-base-64-with-cpp

std::string raw = base64_decode(im64);
        cv::Mat rawData( 1, raw.size(), CV_8UC1, (void*) raw.c_str());

        cv::Mat decodedImage  =  cv::imdecode( rawData, cv::IMREAD_COLOR /*, flags */ );
        cv::imshow("hola",decodedImage);
