##Introduction:
A python version implementation of Combining Sketch and Tone for Pencil Drawing Production。
I think it's interesting when I was introduced the paper.
So even I know little about the area of image processing, I try to read the paper and find some open source implementation to help me understand.
I still have some confusion about the method, but finally I use python to reproduce the result.
This project is developed and tested on Mac OSX 10.10.5 with python 2.7.11 and Ubuntu 14.04 with python 2.7.6
clone this repository
git clone [email protected]:duduainankai/pencil-python.git
cd pencil-python
dependency
The packages you need to install:
Scipy
numpy
Pillow
PS.
If you want to try the color pencil draw method, you need to install opencv in your environment, if just pencil draw wanted, the packages above is enough.
To be honst, how to correctly install opencv is still a question for me. When I search it on google, someone just told me that use homebrew(or apt-get) is OK, but others said it's a wrong way and list many steps should be gone through.
I really got confused so at first I try my best not to use the opencv functions. But when I got to the last step(changing color from Ycbcr to RGB), I did all I can but still failed. Finally, I simplely use homebrew or apt-get to install, and fortunately it works well.
run the program
python draw.py --p -img img/sign.png- there should be a floder named output where you can find the productions
python draw.py -h- for more arguments and explaination
Here are some original picture and productions of the method.

-
maybe an online version pencil drawing service
-
figure out deeper insight of the paper and maybe refactor the code
