title: What does cv::normalize(_src, dst, 0, 255, NORM_MINMAX, CV_8UC1);
body: <p>What does the <code>cv::normalize(_src, dst, 0, 255, NORM_MINMAX, CV_8UC1);</code> do in OpenCV?</p>
  
  <p>I went through  the documentation and was unable to understand what <code>alpha</code>, <code>beta</code>, <code>NORM_MINMAX</code> and <code>CV_8UC1</code> actually do. I am aware alpha sets the lower and beta the higher bound. <code>CV_8UC1</code> stands for an 8-bit unsigned single channel. But what exactly these arguments do to the picture is what I am unable to comprehend.</p>
