# Function Overview ## **Tracing Sutures (Interactive Path Tracing in 2D Images)** _This project seeks to develop a GUI enabling users to interactively create and extract paths in 2D images._ --- ## **Functions List** - 'set_img_path' - Takes the path to the image as input. - Sets self.path. - Is triggered on button click. - 'load_img' - Takes self.path as input. - Displays the input image on the GUI. - Is triggered on button click. - 'start_edit' - Takes no input. - Sets self.editEnabled to true. - Is triggered on button click. - 'calc_gradients' - Takes self.path as input. - Calculates gradients in input image and saves as self.gradient - Is triggered by 'load_img'. - 'set_point' - Takes no input. - Creates a point of the spline on the image when the users clicks left clicks. - Adds the point to self.points. - 'remove_point' - Takes no input. - Removes the point the user is hovering over when the user right clicks. - Removes the point from self.points. - 'update_alpha' - Updates self.alpha. - Is triggered by slider. - 'update_beta' - Updates self.beta. - Is triggered by slider. - 'active_contour' - Takes self.points, self.gradient, self.alpha and self.beta as inputs. - Performs active contour for finding the curve. - Displays the found _snake_. - 'set_export_path' - Sets self.exportPath to the path chosen (by GUI-popup?) by the user. - 'export_line' - Takes self.exportPath as input. - Creats a new np-array file on the chosen path containing the found snake. ## 📎 **Notes** _This is only a rough first draft/overview of the functions needed for the project._ --- **Author:** Christian Bjerregaard **Date:** 07-01-2025
