Maximally stable extremal region extractor

[msers, bboxes] = obj.detectRegions(img)

Input

• img Input 8-bit grayscale or color image (supports 1/3/4-channels). Must be greater or equal than 3x3.

Output

• msers The output vector of connected points (list of point sets). Cell-array of 2D points matrices {[x,y; x,y; ..], [x,y; x,y; ..], ..}.
• bboxes Output matrix of rectangles (bounding boxes). A N-by-4 matrix [x,y,width,height; ...].

Runs the extractor on the specified image; returns the MSER regions, each encoded as a contour (see cv.findContours).
