单个图像超分(SISR)指的是给定一张低分辨率的图像(LR),利用超分算法重构出一张对应的高分辨率图像(HR)。 首先,真实场景下的图像退化过程可表述为: 其中:X为HR图像,Y为LR图像,D为退化模型,θD退化模型中的参数。 SISR旨在对退化过程进行逆处理,以获取潜在的HR图像,该过程可表示为: 其中:R表示超分函数,θR...
对于LR输入图像,SR技术可以分为两大类,即单图像超分辨率(SISR)和多图像超分辨率(或多帧超分辨率)。由于SISR只需要一个输入LR图像就可以生成相应的HR图像,因此更接近日常生活环境,从而引起了研究人员的关注。 早期的SISR技术可分为两种: 基于学习的方法: 这类SISR方法使用机器学习技术来估计HR图像。基于像素的方法和...
SRFormer 是一种基于 Transformer 架构的图像超分辨率(Single Image Super-Resolution, SISR)模型。它旨在通过深度学习技术,从低分辨率图像中恢复出高分辨率图像。SRFormer 利用了 Transformer 模型中的自注意力机制,并引入了置换自注意力(Permuted Self-Attention)机制来优化图像超分辨率任务。 2. 阐述Permuted Self-Atten...
Single Image Super-Resolution (SISR) which aims to recover a high resolution (HR) image from a low-resolution (LR) image has a wide range of medical applications. In this paper, we present a novel Super-Resolution Coarse-to-Fine Network (SRCFN) that recovers the finer texture details ...

Single image super-resolution (SISR) is an important task in computer vision and image processing. Given a low-resolution image, the goal of super-resolution (SR) is to generate a high-resolution (HR) image with necessary edge structures and texture details. The advance of SISR will immediatel...
