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
