Revolutionizing Medical Image Classification with Hybrid Gabor Deep Learning
This paper introduces a lightweight hybrid model combining a Gabor filter bank front-end with compact neural networks for efficient medical image feature extraction and classification. It achieves competitive accuracy with significantly reduced computational cost and faster inference times compared to traditional deep learning models, making it ideal for resource-constrained environments.
Executive Impact: Drive Efficiency & Innovation
Our hybrid Gabor deep learning model offers a game-changing solution for medical image analysis, providing up to 15x faster inference and 4-6x faster training while using fewer parameters (around 0.34M) and FLOPs (around 0.60 GFLOPs) than MobileNetV2 and EfficientNetB0. This translates to substantial cost savings and accelerated diagnostic capabilities for healthcare providers, particularly in settings with limited computational resources or large image volumes. The model maintains high accuracy, demonstrated across diverse medical datasets (MRI, X-ray, dermatoscopic, microscopic, CT), ensuring reliable and efficient decision-making in clinical applications.

Interpreting Model Decisions with Grad-CAM
Description: Grad-CAM heatmaps reveal the regions of an image the model focuses on for classification.
Challenge: Black-box nature of deep learning models, making it difficult to understand diagnostic reasoning.
Solution: Our hybrid model generated more localized and focused heatmaps on relevant regions, indicating refined attention. Pre-trained models often showed broader, less specific heatmaps.
Result: Improved interpretability, confirming that the Gabor front-end combined with a compact classifier leads to efficient and precise feature extraction.
