2013-08-05 08:04:17 -0600	commented question	findContours of vector<Point> Yes. Because I can not handle all regions at once. For example, to add all regions in one image and find contours in one image. Because some regions may overlap each other, Therefore, I can lose some information. So I need to go through each region separately.

2013-08-05 07:57:36 -0600	asked a question	findContours of vector<Point> Hello everyone, I used MSER to get the regions of interest. The `mser` function in OpenCV provides the `vector<vector<Point>>` as output. The `vector<Point>` contains all points that belong to one entire region. I would like to find the contour of each region by using the function `findContours()`. This function requires `Mat` as input argument. My first attempt was to create a `Mat` with zero-values, than go through all points of one particular region and set the value of `Mat` at the corresponding coordinates to max value (255). After the points of one region were set in `Mat`, the `findContours` was run. However, the process of all regions in this way, take long time. Is there another way to find contours of each region? Smth like `findContours(Mat(vector<Point>)` does not work for me. Because `Mat(vector<Point>)` returns Mat with 2 channels. Thank you in advance.
2013-07-10 12:24:16 -0600	commented question	How do I draw irregular contours of MSER regions One mser region, what you get from opencv, contains all points that are belong to one extracted region. So mser region is not a contour of the region. You can find the outer contour by going through every pixels of one region. Find minX and maxY for every Y value that are present in one region. So the result will be an outer contour.
