+# 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._
