ISO国际标准，英文版

ISO12233分辨率测试卡使用说明（又名标准解析力测试图），

2000年的完整原版英文文档，网上的相关资源太贵了，我花了好几十积分才下载下来，现在分享给更多有需要的人。

对图像质量标准 ISO12233-2017 进行了中文翻译，带英文

sfr国际标准算法 ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

ISO国际标准，英文版，Resolution and SFR 影像分辨率空间频率响应的测量标准，介绍了视觉分辨率、e-SFR、s-SFR的测量方法。

国际标准SFR算法，标准文档ISO12233，SFR（spatial frequency response）表示空间频率响应，表示的也是相机的解像能力
