I have a result of watershed algorithm as follows: watershed.png
How would I find all the separate areas of blobs I have in this result?
Have a look at the coin segmentation example using watershed. If you calculate the distance transforms, than threshold it strictly and then look for separate blobs you have what you need..
Thank you for your answer. I need to filter the blobs based on areas resulting from watershed. How would I get those areas?
You are retrieving the watershed regions as markers. These are basically points that have a specific ID. You can add all the points to a vector<Point>, then call convexHull which will return a contour and on top of that you can apply the function contourArea which can then be used to sort or filter your regions.
