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.
