Description
Summary:This article examines evaluation metrics for the results of super-resolution image generation in solving the SISR task. The study comprises two experiments: the implementation of custom network architectures for SRGAN, VDSR, and SRCNN, and fine-tuning of pre-trained SRGAN, VDSR, and SRCNN models. An algorithm for assessing the quality of models and deep learning methods for generating super-resolution images is suggested. The VDSR model performed best in terms of pixel, structural, and perceptual metrics, as well as training time and visual confirmation by a human, highlighting that residual learning is more effective than recursive learning under the conditions of the two conducted experiments. Threshold values for practically acceptable and high-quality results were determined through visual analysis of many generated images and their corresponding quality metrics, including those reported by other researchers.
