The "star shaped search" detection algorithm seems to function with reduced range and [by angle] only in the first quarter of its detection area (counter-clockwise / positive z angles from x-axis, right-handed coordinate-system).
The images below show the output using only this algorithm (other detection methods, blind spot correction and output polygon simplification turned off).
[red line = polygon connecting the detected points]
