Color Space Comparison of Isolated Cervix Cells for Morphology Classification
This study investigates the use of color space transformations as a preprocessing technique to reorganize visual information and improve classification performance using isolated cell images. Twelve color space transformations were compared, including RGB, CMYK, HSV, Grayscale, CIELAB, YUV, the individual RGB channels, and combinations of these channels (RG, RB, and GB). Two classification strategies were employed: binary classification (normal vs. abnormal) and five-class classification. The SIPaKMeD dataset was used, with images resized to 256 × 256 pixels via zero-padding. Data augmentation included random flipping and ±10° rotations applied with a 50% probability, followed by normalization. A custom CNN architecture was developed, comprising four convolutional layers followed by two fully connected layers and an output layer. The model achieved average precision, recall, and F1-score values of 91.39%, 91.34%, and 91.31% for the five-class case, respectively, and 99.69%, 96.68%, and 96.89% for the binary classification, respectively; these results were compared with a VGG-16 network. Furthermore, CMYK, HSV, and the RG channel combination consistently outperformed other color spaces, highlighting their potential to enhance classification accuracy.

Lightweight CNN for Cervical Cancer Screening
The study designed a custom Convolutional Neural Network (CNN) model with only four convolutional layers, followed by two fully connected layers. This architecture was explicitly chosen to offer a computationally efficient alternative for classifying cervical cell images into two and five categories. The LeNet model served as its base, with parameters determined via an exhaustive grid search. This lightweight design allows for faster processing and potentially more portable applications, a critical factor for medical diagnostics in resource-constrained environments. By focusing on essential feature extraction, this CNN demonstrates that high diagnostic accuracy can be achieved without the overhead of more complex, larger models, making it a practical solution for real-world cervical cancer screening.
- Achieved high accuracy with fewer layers.
- Reduced computational overhead for faster deployment.
