A pure python library that implements abstraction of data.

python3 -m pip install --upgrade pyrebel

git clone https://github.com/ps-nithin/pyrebel
cd pyrebel
python3 -m pip install .

Demo programs are found in 'demo/' directory.
cd demo/

Usage:
python3 pyrebel_main.py --input <filename.png>

Optional arguments
--abs_threshold <value> Selects the threshold of abstraction. (Defaults to 5)

For example,
python3 pyrebel_main.py --input images/abc.png --abs_threshold 10

The output is written to 'output.png'

This is a demo of edge detection achieved using data abstraction.
Usage:
python3 pyrebel_main_edge.py --input <filename>

For example,
python3 pyrebel_main_edge.py --input images/wildlife.jpg

The output is written to 'output.png'.Below is a sample input image,


Below is the output image,

This is a demo of 2D sketch formation using data abstraction.
Usage:
python3 pyrebel_main_vision.py --input <filename>

Optional arguments for tweaking the result,

1. --edge_threshold <value> Selects the threshold of edge detection.(Defaults to 5)
2. --abs_threshold <value> Selects the threshold of output abstraction. (Defaults to 10)
3. --bound_threshold <value> Selects the threshold of boundary size. (Defaults to 100)
   
   

For example,
python3 pyrebel_main_vision.py --input images/lotus.jpg

Below is a sample input image,


Below is the output image,

This is a demo of pattern recognition achieved using data abstraction.

1. Learning
   Usage:python3 pyrebel_main_learn.py --learn /path/to/image/directory/
   For example runningpython3 pyrebel_main_learn.py --learn images/train-hand/ learns all the images in the directory and links the filename with the signatures.
   
   
2. Recognition
   Usage:python3 pyrebel_main_learn.py --recognize <filename>
   For example runningpython3 pyrebel_main_learn.py --recognize images/recognize.png displays the symbols recognized in the file 'images/recognize.png'.

To reset the knowledge base just delete file 'know_base.pkl' in the current working directory.The program expects a single pattern in the input image. Otherwise, a pattern has to be selected by changing variable 'blob_index' accordingly.
