lsd_modern (WIP)

C++ code to try to modernize the original Line Segment Detect code

Line Detection Comparison

Image comparison between pytlsd C++ (left) and Opencv C++ (right).

Table with the comparison (ms) of the different parts of the code:

	OpenCV (C++)	pytlsd (C++)	lsd_modern
Gaussian Blur	0.5	43	8
Gaussian Downsample	1.5	31	10
Total	48	214
