trace¶
This package implements tracing routines for solar physics data.
sunkit_image.trace Module¶
This module contains functions that will the trace out coronal loop-like structures in an image.
Functions¶
|
Implements the Oriented Coronal CUrved Loop Tracing (OCCULT-2) algorithm for loop tracing in images. |
|
Applies a band pass filter to the image. |
|
Finds the radius of curvature at the given loop point and then uses it to find the next point in the loop. |
|
Makes all the points in a loop and its vicinity as zero in the original image to prevent them from being traced again. |
|
Finds the initial angle of the loop at the starting point. |
|
Adds the current loop to the output structures by interpolating the coordinates. |
