摘要

Generative-Adversarial-Networks (GANs) have demonstrated notable/significant potential in the area/field of image-synthesis, especially in the areas of image-generation and image to image translation. In this work, we explore the capabilities of GANs through two distinct implementations. First, we utilize a regular GAN, to generate synthetic images belonging to MNIST and CIFAR-10 datasets, illustrating the network’s proficiency in creating diverse and realistic images from different data distributions. Second, we apply the Pix2Pix GAN model for image-to-image (I2I) translation, focusing on converting satellite images into maps, a task that highlights the model’s capability/ability to learn intricate mappings between paired datasets. Our results underscore the versatility of GANs in generating high-quality images and performing complex image translation tasks. In this study, for generating images of MNIST handwritten digits, the discriminator has a loss of 0.57 and an accuracy of 82%, while the generator has a loss of 0.52. For the CIFAR-10 dataset, the discriminator’s loss is 0.629 when dealing with real images and 0.51 when dealing with fake images, with the generator’s (basically a CNN), loss at 0.897. In the image translation task using Pix2Pix on the maps dataset, the discriminator’s loss is 0.6 for real images and 0.4 for unreal images, while the generator’s loss is 0.61. In each of the GAN architectures, the discriminator, the generator, and the combined GAN model are carefully designed and trained accordingly. These findings demonstrate the effectiveness of GANs in both generating diverse, high-quality images and performing precise image-to-image translation. The results validate the robustness and adaptability of GAN architectures across different datasets and tasks, reinforcing their potential for advanced image synthesis apps/applications.
