Sketchy Turtle:turtle:

A turtle that (almost) sketches any image given to it.



Directions to use:

  1. Clone this repo: git clone https://github.com/hrshtv/Sketchy-Turtle.git
  2. Run: python3 sketch.py -in <input_img_path> -o <output_file_path> -wt <width> -ht <height>
    • -in (--input) : The input image's path
    • -o (--output) : The output file's name. The output will be an .eps file, provide only the name without any extensions
    • -wt (--width), -ht (--height) : Decides the shape (width, height) to which the input image will be resized to. This is also the canvas size on which the turtle will draw.

Improvements/To-do

  • Try other autothresholding methods like the Otsu's method and compare the results
  • Increase the efficiency of the sketching program
    • Currently some edges detected are very thick, which increases time taken unneccesarily, try edge thinning algorithms
    • While finding closest neighbours, omit the points that are too close to one another, to decrease the input size
    • Ramer–Douglas–Peucker algorithm
