false detection and ghost points

[ajay1606]

Hello,

Thanks for the very useful repository, am able to test run code with the custom dataset.
But observed a few issues as shown in the following result images.

1. 1 Failed to detect lines in the turing
2. 2 and 3 Partially detected lines in turning
3. 4 Road arrow marks are also detected as lane
4. 5 Though there are no lanes, the detection algorithm outputs the detected line

Any suggestion, much appreciated.

Regards,
Ajay
