PSR4K
收藏资源简介:
PSR4K数据集由500张分辨率为960×540像素的低分辨率图像组成,这些图像通过多种降质类型进行降质,但没有提供原始的高质量图像。该数据集旨在反映实际部署条件,并作为多样性和挑战性的基准。数据集被分为十个类别:动物、建筑、艺术、食物、自然、物体、肖像、运动、文本和城市场景。每个类别都应用了五种不同的降质,包括各种下采样方法、模糊和JPEG压缩。
The PSR4K dataset consists of 500 low-resolution images with a resolution of 960×540 pixels. These images are degraded via various degradation types, while no original high-quality images are provided. This dataset is designed to reflect real-world deployment conditions and serve as a diverse and challenging benchmark. The dataset is divided into ten categories: animals, architecture, art, food, nature, objects, portraits, sports, text, and urban scenes. Five distinct degradation methods are applied to each category, including various downsampling approaches, blurring, and JPEG compression.
