Summary
This study introduces an optimized image processing strategy for accurate brain tumor segmentation. The approach combines Gabor transform, Genetic Algorithm (GA), and Neuro Fuzzy System (NFS) for high-sensitivity detection.
Area of Science:
- Medical Imaging
- Artificial Intelligence
- Biomedical Engineering
Background:
- Early detection and accurate segmentation of brain tumors are critical for effective patient treatment.
- Existing image processing techniques may face challenges in precisely identifying and delineating tumor regions.
Purpose of the Study:
- To propose a novel transform- and windowing-based optimization strategy for brain tumor exposure and segmentation.
- To enhance the accuracy and reliability of brain tumor detection and classification using advanced computational methods.
Main Methods:
- Image preprocessing, Gabor transform for multi-resolution conversion, feature extraction, and feature optimization using Genetic Algorithm (GA).
- Classification of tumor regions using a Neuro Fuzzy System (NFS), followed by segmentation using a normalized algorithm.
Main Results:
- The proposed GA-based NFS classification approach demonstrated high performance in brain tumor detection and classification.
- Achieved average results including 99.37% sensitivity, 98.9% specificity, and 99.21% accuracy.
Conclusions:
- The integrated image processing strategy effectively segments brain tumors, offering a promising tool for clinical application.
- The high accuracy and sensitivity indicate the potential of this method for improving patient screening and diagnosis.
