title: Eroding Text to from blobs OpenCV
body: <p>I need to detect text blocks on a document and get back their bounding boxes, I have heard that I should erode the image which will "smudge" the text together and form blobs, then I can use blob detection to find where the text is. Currently I have I binarized image with some text on it. </p>
  
  <p>I have been using this code to erode, and it is slightly merging the text together. But how can I make it more severe? The parameters have me slightly confused and if someone could explain how I could make the erosion harsher that would be great!</p>
  
  <p><code>erode(quad, quad, Mat(), cv::Point(-1, -1), 2, 1, 1);</code></p>
  
  <p>Thanks.</p>
