Description

For LineSegmentDetector, python bindings support only LSD_REFINE_ADV flag. For other two flags, it throws assertion error.

img = cv2.imread('test.jpg',0)
LSD = cv2.createLineSegmentDetector(0) # LSD_REFINE_NONE
a = LSD.detect(img)

OpenCV Error: Assertion failed ((!_nfa.needed()) || (_nfa.needed() && doRefine >= LSD_REFINE_ADV)) in detect, file /run/media/abidrahmank/OFFICE/repos/opencv/modules/imgproc/src/lsd.cpp, line 431

It is caused due to inability to pass optional output argument in Python bindings.
