Makes puzzle from an image and tries to solve it using OpenCV and numpy data types.

  • puzzle.py: converts given images into puzzle of given dimension of pieces
  • unpuzzle.py: solves given puzzle image consisting of given dimension of pieces

Requirements

  • Python3
  • OpenCV
  • numpy

Instructions

Puzzling Image

[usage]:      python3 puzzler.py file_name pieces_vertically pieces_horizontally
[example]:  $ python3 puzzler.py lenna.png 4 3

puzzler.py will make a puzzle of dimension pieces_vertically X pieces_horizontally from given file_name. Result image is stored as file_name_puzzle.png.

The example command will create a 4 X 3 pieces puzzle of lenna.png, stored as lenna_puzzle.png.

Result puzzle image of lenna.png

Unpuzzling Image

[usage]:      python3 unpuzzler.py file_name pieces_vertically pieces_horizontally
[example]:  $ python3 unpuzzler.py lenna_puzzle.png 4 3

unpuzzler.py will solve a puzzle of dimension pieces_vertically X pieces_horizontally from given file_name. Result image is stored as file_name_solve.png.

The example command will attempt to solve a 4 X 3 pieces puzzle of lenna_puzzle.png, stored as lenna_puzzle_solve.png.

Result unpuzzle image of lenna_puzzle.png

Advanced

If unpuzzling does not rearrange pieces correctly, play around with threshold values PIXEL_DIFFERENCE_THRESHOLD and DIFFERENCE_RATE_THRESHOLD in Piece.py.
