Fuzzy Surface Creation
General Information
Data sharing became a big issue in the last few years. Unfortunatly for research data sharing is a difficult undertaking because of patient privacy protection. This constricts the exchange of data secific data between different research groups and faculties.
MRI and CT data itself wouldn't be that delicate since the identification of a patient isn't obvious. But the rendering of the data into a 3D view reveals a lot of information about the skin and skull structure of a patient and therefore makes a patient easily identifiable.
The purpose of this module is therefore to hide as much surface information of the patient as possible but also to keep internal structures untouched.

Module Description
The purpose of this module is to hide as much surface details of a patient as possible. Therefore it adds an additional surface to the front of the object in the image depending on different calulated parameters.
As a first step the module detects the object in the image. Subsequent it adds additional data on the detected surface depending on several calculated parameters. As a result it creates an additional surface on the object which hides skin and skull details so that patient identification isn't obvious any more.
Usage
This module is a CLI Module for Slicer. It is mainly seperated into two parts:
- Otsu Threholding
- Fuzzy Surface Creation
The first step is meant to be the pre-processing step. The Otsu - Threshold - Filter provides quite good segmentation results on the object in the image and is considerably robust against noise, especially for one which is not connected to the object.
The pre-processing task defines the following parameters:
- bright objects
- number of histogram bins
- Face connected
- Minimum object size
For further information about these parameters check the Otsu - Threhold - Filter in Slicer3.
