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

occult2(image, nsm1, rmin, lmin, nstruc, ...)	Implements the Oriented Coronal CUrved Loop Tracing (OCCULT-2) algorithm for loop tracing in images.
bandpass_filter(image[, nsm1, nsm2])	Applies a band pass filter to the image.
curvature_radius(image, rmin, xl, yl, zl, ...)	Finds the radius of curvature at the given loop point and then uses it to find the next point in the loop.
erase_loop_in_image(image, istart, jstart, ...)	Makes all the points in a loop and its vicinity as zero in the original image to prevent them from being traced again.
initial_direction_finding(image, xstart, ...)	Finds the initial angle of the loop at the starting point.
loop_add(lengths, xloop, yloop, zloop, ...)	Adds the current loop to the output structures by interpolating the coordinates.
smooth(image, width[, nanopt])	Python implementation of the IDL's smooth.
