inverse GSDF

In order to invert GSDF image to original Dicom image, GSDF's transfer function have been regressed through various method: Linear regression, and Non-linear regresstions such as Cubic, and Spline.

• How to run
• Description

How to run

1. Install python 3.9 or later, then assure its version via below command line

python -V

2. Install dependencies, type below command at the directory, where "requirements.txt" file is located

pip install -r requirements.txt

3. Run "RunThis_for_evaluate.py" to evaluate various regression methods:

python RunThis_for_evaluate.py

3. Run "RunThis_for_conduct_inverse_GSDF.py" to conduct inverting GSDF and dump its resultants:

python RunThis_for_conduct_inverse_GSDF.py

Description

In this case, 'partial cubic regression' is the best way for estimating inverse GSDF transfer function. TBD in details ...
