initial_direction_finding¶
- sunkit_image.trace.initial_direction_finding(image, xstart, ystart, nlen)[source]¶
Finds the initial angle of the loop at the starting point.
- Parameters:
image (
numpy.ndarray
) – Image in which the loops are being detected.xstart (
int
) – Thex
coordinates of the starting point of the loop.ystart (
int
) – They
coordinates of the starting point of the loop.nlen (
int
) – The length of the guiding segment.
- Returns:
float
– The angle of the starting point of the loop.
