- Machine learning (ML) offers potential for faster, more accurate diagnoses.
Purpose of the Study:
- To develop and validate an ML approach for automated polyp detection in lower endoscopies.
- To improve diagnostic accuracy and sensitivity in endoscopic procedures.
- To provide a tool that assists physicians, especially during training.
Main Methods:
- Utilized machine learning algorithms for polyp detection.
- Applied wavelet transform for feature extraction from endoscopic images.
- Trained and validated the system on a dataset of 1132 lower endoscopy images.
Main Results:
- Achieved 97.9% accuracy in diagnosing polyps.
- Demonstrated approximately 10% greater efficiency compared to previous low-computational methods.
- Reported a false positive rate of 0.03.
Conclusions:
- The proposed ML system demonstrates high accuracy and sensitivity for polyp detection.
