摘要

With the rapid advancement of neural networks, image super-resolution models based on convolutional neural networks have significantly progressed, consistently enhancing image reconstruction quality and detail preservation capabilities. However, deploying these sophisticated models on resource-constrained edge devices presents substantial challenges with respect to computational resource allocation and data storage requirements. To address the limitations of large models with high parameter counts and computational demands that render them unsuitable for edge devices, we propose a Lightweight Shuffle Feature Fusion Network (LSFFN). Our approach introduces two key innovations. First, we design a lightweight multi-scale shallow feature extraction module that employs depthwise separable convolutions and channel-shuffle operations, effectively reducing the computational overhead associated with multi-scale feature extraction. Second, we implement a shuffle feature fusion structure that preserves image details while facilitating efficient feature fusion in a resource-efficient manner, thus mitigating the performance degradation commonly observed in lightweight SR models. Compared with state-of-the-art lightweight SR methods, our proposed method demonstrates better performance. For instance, LSFFN outperforms IFIN-S by over 0.09 dB in PSNR and 0.0033 in SSIM when evaluated on the Urban100 ( \(\times \) 4) dataset. Comprehensive evaluations demonstrate that LSFFN achieves enhanced reconstruction fidelity while significantly reducing parameter count and computational requirements, effectively striking an optimal balance between processing efficiency and image quality performance in resource-constrained environments.
