Can OpenCV do these processing?

I am working on an OCR project. I need to do some pre-processing similar to the link below: http://cn.mathworks.com/help/vision/e...

The steps are:

  • Region detection (MSER)
  • Edge detection (Canny)
  • Connected Component Analysis (for character candidates filtering)

I am not familiar with OpenCV. I am wondering if OpenCV can do all of these.

  1. There is MSER feature detector or dev docs
  2. Canny edge detector is a function of OpenCV too
  3. There is no function that is named "Connected Component Analysis", but on google, you can find many interesting things that may help you (e.g.: findContours, or moments) BTW, I am mistaking: I have found it, but it seems that it is just in OpenCV 3.0, because it is unknown, maybe I have not the last version of 2.4
