We have used the provided code for the EIT image reconstruction with the following modifications:
- The Otsu segmentation algorithm has been replaced by the Chan-Vese segmentation algorithm from scikit-image.
- Additional generalized Tikhonov regularization has been added to penalize more when close to the missing electrodes (and boundary). The regularization matrix is a diagonal matrix. For example, for difficulty level 5, the amount of penalty added to different regions of the image, can be seen in the image below:
To run our EIT image reconstruction algorithm, you will need:
- Python 3.x
- Required Python libraries (listed in
requirements.txt
) - Access to the provided dataset (not included in this repository)

Scores for each phantom and difficulty 1,4 and 7:
Phantom | Level 1 | Level 4 | Level 7 |
---|---|---|---|
a | 0.835 | 0.737 | 0.526 |
b | 0.761 | 0.563 | 0.499 |
c | 0.942 | 0.918 | 0.844 |
d | 0.767 | 0.774 | 0.751 |
Scores have been computed using our own implementation of the scoring function based on scikit learn.
