Hello
I extract parts of the lungs from the CT scans, but in some cases this extraction is not done properly.
There are many images in the database. How do you think I can recognize and delete these images that have not been extracted correctly?
Thanks

There are multiple ways through which you can achieve the same:
1) Using basic statistics to detect anomalies such us unusually high or low pixel intensities in the images.
2) If the extraction process should result in a specific shape or size (e.g., lung shapes), you can use morphological analysis. You can refer to the following MathWorks documentation for more details related to morphological operations:

3) Creating a machine learning or deep learning image classification for the same. You can refer to the following MathWorks documentation to train an image classifier:

I hope this helps.
