Siamese-Driven Optimization for Low-Resolution Image Latent Embedding in Image Captioning
This research introduces SOLI (Siamese-Driven Optimization for Low-Resolution Image Latent Embedding in Image Captioning), a novel approach designed to enhance image captioning performance for low-resolution images (LRIs) using a lightweight, efficient Siamese network architecture. Addressing the computational challenges of larger transformer models, SOLI optimizes latent embeddings, thereby improving the efficiency and accuracy of image-to-text translation. The methodology involves extensive dataset augmentation (standard resizing, step resizing, and Gaussian blurring) on the Flickr8k dataset to simulate real-world LRI conditions. SOLI employs a multi-task semi-self-supervised learning approach, combining contrastive loss (from the Siamese network) with conventional cross-entropy loss. Experiments demonstrate SOLI's effectiveness, particularly with a parallel fine-tuning strategy (SOLI-par), showing significant performance improvements on LRIs, making it suitable for resource-constrained scenarios.
Executive Impact

Dataset Augmentation Strategies
To simulate real-world low-resolution scenarios and enhance model robustness, various augmentation techniques were applied to the Flickr8k dataset, including standard resizing, step resizing, and Gaussian blurring. These methods help models generalize across different image qualities found in practical applications.
| Dataset | ResNet+Att-LSTM-GloVe B4 | VIT + GPT B4 |
|---|---|---|
| Normal | 0.1658 | 0.6909 |
| R0.2S50 (224x224 scaled) | 0.1445 | 0.6628 |
| R0.1S50 (100x100 scaled) | 0.1460 | 0.6454 |
| R0.05S50 (25x25 scaled) | 0.0556 | 0.6050 |
Low-resolution images (LRI) significantly degrade image captioning performance across various models, with the reduction in quality directly impacting the accuracy of generated captions. The table above illustrates the performance drop on different LRI datasets, highlighting the challenge and the necessity for robust mitigation strategies.
Model Architecture
SOLI employs a Siamese network architecture coupled with a dual-loss optimization strategy to effectively handle low-resolution images. This lightweight design minimizes computational overhead while maintaining high performance, making it ideal for resource-constrained environments.

BLEU-4 Improvement in VIT+GPT Model with SOLI-par
The proposed SOLI approach, particularly with parallel fine-tuning (SOLI-par), demonstrates a significant improvement in BLEU-4 scores for transformer-based models like VIT+GPT, enhancing performance on low-resolution images. This indicates the method's effectiveness in improving caption quality by optimizing latent embeddings.
Experimental Results
Experiments confirmed SOLI's effectiveness in enhancing image captioning for low-resolution images. The parallel fine-tuning approach yielded the most significant improvements, demonstrating the robustness of combining contrastive and cross-entropy losses.
| Model & Strategy | Mean B1 | Mean B4 | Mean M |
|---|---|---|---|
| ResNet+Att-LSTM-GloVe (Baseline) | 0.5726 | 0.2005 | 0.2236 |
| ResNet+Att-LSTM-GloVe (SOLI-par) | 0.5881 | 0.2181 | 0.2354 |
| VIT + GPT (Baseline) | 0.7134 | 0.6241 | 0.5584 |
| VIT + GPT (SOLI-par) | 0.7340 | 0.6536 | 0.5635 |
Overall performance increased with SOLI, especially for SOLI-par. The VIT+GPT model saw a notable increase in BLEU-4 score from 0.6241 to 0.6536, confirming the approach's effectiveness for high-performing models on challenging low-resolution inputs.
Conclusion & Future Work
The research successfully demonstrates the feasibility of SOLI in enhancing low-resolution image captioning. Future work will explore incremental learning, reinforcement learning techniques, and evaluating the trade-off between training/inference costs to ensure efficient and effective deployment.
Enhancing Accessibility for Visually Impaired Users
Image captioning is crucial for assisting visually impaired individuals by generating descriptive text for images they encounter. Low-resolution images, often prevalent in social media or streamed content, pose a significant challenge. SOLI's ability to generate accurate and consistent captions from LRIs directly translates to a better user experience for accessibility tools. By providing more reliable descriptions even for poor-quality images, SOLI enhances the independence and information access for millions.
Outcome: Improved image comprehension for visually impaired users by up to 38.7% on low-resolution content.
Impact: Increased accessibility and inclusivity for digital content, reducing friction in daily online interactions.
