Detection and classification of brain tumor using a hybrid learning model in CT scan images
This study proposes a novel hybrid learning framework for the detection and classification of brain tumors from CT scan images, addressing challenges like model complexity and generalization. The model integrates hand-crafted features (LBP, HOG, median intensity) with deep features from pre-trained ResNet50 and AlexNet. Feature selection using SelectKBest optimizes performance, and classification is performed by a multilayer perceptron (MLP). The model achieved an accuracy of 94.82%, precision of 94.52%, specificity of 98.35%, and sensitivity of 94.76%. Unlike MRI-based models, this method is specifically designed for CT scans, offering a more accessible and faster alternative for early-stage screening, reinforcing its practical clinical value.
Executive Impact: At a Glance
The proposed hybrid model delivers significant performance improvements, crucial for early and accurate brain tumor diagnosis in clinical settings, particularly for CT scan images. These key metrics highlight the model's robustness and potential for real-world application.

CT vs. MRI in Brain Tumor Diagnosis
While MRI is a common modality for brain tumor diagnosis, its high cost and longer acquisition time make CT scans a more practical choice for early-stage screening. The proposed CT-based model demonstrates strong generalization despite modality differences, achieving competitive accuracy with leading MRI-based approaches.
| Feature | MRI-Based Models (Typical) | Proposed CT-Based Model |
|---|---|---|
| Cost | High | Lower |
| Acquisition Time | Longer | Faster |
| Accessibility | Limited | More Accessible (Emergency/Screening) |
| Soft-Tissue Contrast | High | Lower, but addressed by preprocessing |
| Typical Accuracy (Range) | 97-99% (often higher for MRI-only) | 94.82% (on CT, competitive) |

The Power of Feature Fusion
The integration of hand-crafted features (LBP, HOG, median intensity) with deep features from pre-trained ResNet50 and AlexNet forms a comprehensive feature space. This fusion addresses the unique noise patterns and lower soft-tissue contrast of CT scans, enabling the MLP classifier to learn more discriminative representations.
Feature Fusion Case Study
Problem: Traditional feature extraction methods struggle with CT scan's unique noise and lower soft-tissue contrast, leading to suboptimal tumor detection and classification accuracy.
Solution: A hybrid approach combining Local Binary Pattern (LBP), Histogram of Oriented Gradients (HOG), and median intensity with deep semantic features from pre-trained ResNet50 and AlexNet. Followed by SelectKBest for optimal feature selection.
Outcome: This fusion enhances diversity and discriminative power, improving classification robustness and accuracy significantly, addressing the limitations of single-modality or single-feature approaches on CT scan images.
