ofxCvBlob represents an area identified by the OpenCV plug-in as being a contiguous object in the scene. It's most often stored within a contrountFind instance and populated by a call to findContours().
In the image below you can see two blobs detected in the grayscale image:
void ofxCvBlob::draw(float x, float y)
This method draws the blob to the screen with the upper-left corner located at the point specified by the x and y values.
vector< ofPoint > pts
vector< ofPoint > ofxCvBlob::pts
