Çözünürlük artırımı (süper-çözünürlük) belirli bir artırım değeri ile görselin yüksek çözünürlükteki detaylarını korumaya çalışarak boyutlarını artırma işlemidir. Süper-çözünürlük birçok teknik ile gerçekleştirilebilir. Ancak bu konudaki en etkili teknikler çeşitli sinir ağı tasarımlarından yararlanan tekniklerdir. Bazı ağ tasarımları belirli konularda diğerlerine göre daha uygundur. Bu çalışma Üretken Çekişmeli Ağlar ile gerçekleştirilmiş çözünürlük yükseltme işlemlerine odaklanmıştır. Birçok çalışma yapar veri üretimi ve verinin daha anlamlı hale getirilmesi gibi çeşitli konularda bu yapay sinir ağı tipini kullanır. Bu yapay sinir ağı tipi ile yapay veri üretimi ve verinin daha anlamlı hale getirilmesi gibi alanlarda başarılı çalışmalar mevcuttur. Daha gerçekçi sonuçlar üretebilmesi için birbirini yenmeye çalışan iki alt ağdan oluşması bu ağ türünün kilit noktasıdır. Üretilen görselin kalitesini ölçen başarım ölçümleri, sinir ağında kullanılan yitim fonksiyonları ve Üretken Çekişmeli Ağ kullanarak tekil-görsel çözünürlük artırımı üzerine çalışılmış araştırma makaleleri bu çalışmanın temel alanında yer almaktadır.

A Survey on Image Super-Resolution with Generative Adversarial Networks

Öz

Super-resolution is a process to increase image dimensions with a specific upscaling factor while trying to preserve details that matche with the original high-resolution form. Super-resolution can be done with many techniques. But the most effective technique is the one that takes advantage of several neural network designs. Some network designs are more appropriate than others on the specific subject. This study focuses on super resolution studies using Generative Adversarial Network. Many studies use this neural network type to look at various topics such as artificial data production and making the data more meaningful. The key point of this neural network type is having two different sub-networks that try to defeat each other in order to make more realistic results. Performance metrics that measure the quality of a generated image, loss functions used in a neural network and research papers on super-resolution with Generative Adversarial Network are the main domains of this study.
