A Novel Cervical Cancer Detection Using Contrast Overlap Feature-Based Segmentation with Neural Network Classifier
This study introduces the Contrast Overlap Segmentation Method (COSM) for early cervical cancer detection using smear images. It employs a two-layer neural network with ReLU normalization for classifying high/low contrast regions and segmenting overlapping areas. Experimental results on the CCAgT dataset show COSM significantly improves accuracy, precision, and sensitivity compared to existing methods, making it a robust and efficient diagnostic tool, despite an identified overhead with variable feature distributions.

Methodology
This section details the Contrast Overlap Segmentation Method (COSM), which processes smear images using a neural network classifier. It covers image acquisition, feature extraction, contrast-based classification (high/low), segmentation using two hidden layers, and ReLU normalization for precise detection of cancerous regions, including overlapping and non-overlapping areas. The binary feature extraction assigns +1, 0, or -1 values based on pixel intensity relationships to enhance sensitivity to subtle image variations.

Average Accuracy for Cervical Cancer Detection
The proposed COSM achieved an average accuracy of 93.27% in cross-validation (Table 6), demonstrating its high effectiveness in correctly identifying cervical cancer regions from smear images. This superior performance is attributed to the method's contrast-aware feature classification and neural network architecture.
| Metric | LFANet | DSSNS | IBGC-CRF-SPSST | COSM (Proposed) |
|---|---|---|---|---|
| Accuracy | 0.775 | 0.829 | 0.88 | 0.9325 |
| Precision | 0.789 | 0.84 | 0.903 | 0.9402 |
| Sensitivity | 0.891 | 0.917 | 0.929 | 0.9536 |
| Mean Error | 0.09 | 0.078 | 0.064 | 0.0578 |
| Computing Time (s) | 2.08 | 1.72 | 1.21 | 0.883 |
This table showcases COSM's superior performance across key metrics when compared to existing methods like LFANet, DSSNS, and IBGC-CRF-SPSST, based on feature classification rates (Table 4). COSM consistently achieves higher accuracy, precision, and sensitivity while maintaining lower mean error and computing time.
Results & Discussion
This section presents the experimental analysis using the CCAgT cervical cancer dataset, comprising 9339 smear images. It details how COSM's contrast-aware feature classification and neural network processing lead to improved accuracy, precision, and sensitivity, along with reduced mean error and computing time. The discussion includes comparative analyses with other state-of-the-art methods and an ablation study validating the contribution of each module.
Ablation Study Validates Module Contributions
An ablation study revealed that each component of COSM—trinary feature extraction (TFE), contrast-based classification (CBC), overlap/non-overlap segmentation (ONS), and ReLU-based normalization—is critical for optimal performance. Removing TFE led to a 9.2% drop in accuracy, while omitting ONS resulted in the lowest sensitivity and highest mean error. This confirms the integrated architecture is robust and reliable, ensuring precise detection and classification of cervical cancer cells. The complete COSM model achieved the lowest mean error (0.0578s) and fastest computing time (0.883s), underpinning its holistic design.
95.37%
Average Sensitivity for Cancer Detection
COSM achieved an average sensitivity of 95.37% (Table 6), demonstrating its superior ability to correctly identify true-positive cases of cervical cancer, even in complex or overlapping segment boundaries, which is crucial for early and accurate diagnosis.

|---|---|---|---|---|---|
| Fold 1 | 0.9273 | 0.9365 | 0.9498 | 0.0591 | 0.881 |
| Fold 2 | 0.9312 | 0.9404 | 0.9523 | 0.0583 | 0.887 |
| Fold 3 | 0.9336 | 0.9432 | 0.9551 | 0.0572 | 0.879 |
| Fold 4 | 0.9351 | 0.9460 | 0.9562 | 0.0565 | 0.886 |
| Fold 5 | 0.9362 | 0.9450 | 0.9550 | 0.0577 | 0.882 |
| Average | 0.9327 | 0.9422 | 0.9537 | 0.0578 | 0.883 |
The fivefold cross-validation (Table 6) confirms COSM's robustness and consistent high performance across different data splits. The stable average accuracy, precision, and sensitivity, along with low mean error and computing time, prove its reliability and suitability for broad clinical applications without overfitting.
