Advanced Deep Learning Backbones
We evaluated five state-of-the-art architectures, including both conventional CNNs and transformer-based models, to establish a robust baseline and understand their effectiveness in capturing visual freshness cues.
Why Swin-Tiny Excels in Fish Freshness
The Swin Transformer-Tiny (Swin-Tiny) achieved the highest baseline accuracy of 84.85%. Its transformer-based design, leveraging self-attention, allows it to capture both subtle local textural details (e.g., cloudiness of the fish eye lens) and broader spatial patterns, which are crucial indicators of freshness. Its balanced resource usage and high performance make it ideal for practical deployment.
In comparison, ConvNeXt-Base, while similar in performance, demands more computational resources. EfficientNet-B0 offers efficiency but with reduced accuracy, while DenseNet-121 and ResNet-50 provide general features but may struggle with complex spatial relationships.
Superior Accuracy Through Feature Optimization
Our hybrid framework, combining deep features with classical machine learning and advanced feature selection, significantly outperforms deep models alone. This multi-stage approach ensures robust, interpretable, and generalizable results.

Highest Accuracy Achieved: Swin-Tiny + ET + LGBM Feature Selection
The best configuration, utilizing Swin-Tiny features, an Extra Trees (ET) classifier, and LGBM-based feature selection, achieved an accuracy of 85.99%. This highlights the power of optimizing deep representations rather than relying solely on end-to-end deep learning. LGBM's ability to identify truly discriminative features enabled a 90% reduction in feature dimensions without sacrificing performance.
Outperforming Industry Benchmarks
Our framework sets a new standard for fish freshness assessment on the challenging FFE dataset, significantly surpassing previous state-of-the-art methods in terms of accuracy and robustness.
