ITU-T T.840.1 (03/2025)

عربي | 中文 | English | Español | Français | Русский
信息技术 – JPEG 基于人工智能学习的图像编码系统:核心编码系统
ITU-T T.840.1建议书 |ISO/IEC 6048-1规范了一种称为基于JPEG AI学习的图像编码(JPEG AI)技术,该技术的设计具有多任务目标。它有助于人类和机器视觉的图像压缩和处理。本建议书 |国际标准描述了基于JPEG AI学习的标准,用于从解析的单流中创建图像,包含紧凑的压缩域表示,既针对人类可视化,在同等主观质量下比常用的图像编码标准压缩效率显著提高,又针对图像处理和计算机视觉任务的有效性能。核心编码系统描述了用于人类视觉重建任务的JPEG AI标准,从而规定了编码流的解析和图像重建过程。可训练模型参数作为本建议书 | 国际标准的组成部分,因其体量庞大而未包含在规范中。训练后的模型参数可查阅:及(参见第18.2小节)。本建议书 | 国际标准与ISO/IEC JTC 1/SC 29联合制定,其文本与ISO/IEC 6048-1通用。
