It can be challenging to extract valuable information from photographs taken with low-resolution cameras or images that have been deteriorated by noise, blur, or other factors. The ability of conventional image restoration methods to return photos to their original quality is constrained. Thus, there is a need for more sophisticated methods that can improve the quality of restored photos. The goal of this project is to create an image restoration model that can improve low-resolution or degraded photos utilizing post-processing methods along with SRGAN. The project's objective is to build the SRGAN model followed by post-processing methods for image restoration. This project will also investigate how various characteristics, like the size of the training dataset, the number of layers in the network, and the post-processing methods employed, affect the performance of the model. The initiative will aid in the creation of more sophisticated picture restoration methods that may be applied to a variety of situations, including surveillance, remote sensing, and medical imaging.
SRGAN with two models, where these two separate models are pitted against each other simultaneously during training: a generator and discriminator model both attempt to outsmart one another. The Generator takes input data containing a low-resolution version of an image, then up samples it which outputs a high-resolution image. The Discriminator attempts to distinguish between real/fake output generated by G so as D's success rate progresses more accurate results are achieved through feedback loops affecting G till desired accuracy goals have been set. During the training, A high-resolution image (HR) is down sampled to a low-resolution image (LR). A GAN generator up samples LR images to super-resolution images (SR). We use a discriminator to distinguish the HR images and backpropagate the GAN loss to train the discriminator and the generator. This advanced Machine Learning technique uses both generators and discriminators and also uses the pre trained weights called as VGG19 in order to discern between high-resolution original photos and their generated counterparts. As opposed to simply upscaling blurred photos often seen with conventional methods like nearest neighbour interpolation, these AI models produce results that are much closer to the quality as perceived by humans making them perfect for applications such as picture enhancement or dealing with poor digital zoom performance due lack of details produced when enlarging digital images artificially.
