Enhancing the Quality of Satellite Images in Disaster Management: A Comparative Analysis of Zero-DCE, CIDNet, and MIRNet Models

Öz

Satellite images play a critical role in disaster management and rescue operations in natural disasters. However, these images create difficulties in analysis due to noise and loss of detail. This study evaluates the performance of deep learning models—Zero-DCE, CIDNet, and MIRNet—in enhancing low-light satellite images. The performances of the models were analyzed with metrics such as PSNR, SSIM and LPIPS using post-earthquake satellite images of the Hatay region. In addition, the performance of the models on a benchmark dataset was analyzed. The results showed that CIDNet was superior in detail and structural accuracy, while MIRNet was successful in color and brightness enhancement. Although Zero-DCE was effective in brightness enhancement, it lagged behind other models in structural accuracy. In this study, the potential of deep learning-based image enhancement models in disaster management and the image features on which they are effective were revealed.

Doğal Afet Yönetiminde Uydu Görüntülerinin Kalitesinin İyileştirilmesi: Zero-DCE, CIDNet ve MIRNet Modellerinin Karşılaştırmalı Analizi

Öz

Doğal afetlerde uydu görüntüleri, afet yönetimi ve kurtarma operasyonlarında kritik bir rol oynamaktadır. Ancak düşük ışık koşullarında elde edilen bu görüntüler, gürültü ve detay kaybı nedeniyle analizlerde zorluk yaratmaktadır. Bu çalışmada, düşük ışık uydu görüntülerinin iyileştirilmesinde Zero-DCE, CIDNet ve MIRNet modellerinin performansları değerlendirilmiştir. Hatay bölgesine ait deprem sonrası uydu görüntüleri kullanılarak modellerin PSNR, SSIM ve LPIPS gibi metriklerle performansları analiz edilmiştir. Ayrıca modellerin bir kıyaslama veri kümesindeki başarımı da analiz edilmiştir. Sonuçlar, CIDNet’in detay ve yapısal doğrulukta üstün olduğunu, MIRNet’in ise renk ve parlaklık iyileştirme konusunda başarılı olduğunu göstermiştir. Zero-DCE, parlaklık artırmada etkili olsa da yapısal doğrulukta diğer modellere göre geride kalmıştır. Bu çalışmada derin öğrenme tabanlı görüntü iyileştirme modellerinin afet yönetimindeki kullanım potansiyeli ve etkili oldukları görüntü özellikleri ortaya konulmuştur.
