In recent years, several deep learning-based architectures have been proposed to compress Light Field (LF) images as pseudo video sequences. However, most of these techniques employ conventional compression-focused networks. In this paper, we introduce a version of a previously designed deep learning video compression network, adapted and optimized specifically for LF image compression. We enhance this network by incorporating an in-loop filtering block, along with additional adjustments and fine-tuning. By treating LF images as pseudo video sequences and deploying our adapted network, we manage to address challenges presented by the unique features of LF images, such as high resolution and large data sizes. Our method compresses these images competently, preserving their quality and unique characteristics. With the thorough fine-tuning and inclusion of the in-loop filtering network, our approach shows improved performance in terms of Peak Signal-to-Noise Ratio (PSNR) and Mean Structural Similarity Index Measure (MSSIM) when compared to other existing techniques. Our method provides a feasible path for LF image compression and may contribute to the emergence of new applications and advancements in this field.
