Abstract: Embodiments for video content source resolution detection are provided. Embodiments enable systems and methods that measure video content source resolution and that provide image-by-image source scale factor measurements to picture quality (PQ) processing modules. With the source scale factor information, PQ processing modules can be adapted dynamically (on a picture-by-picture basis) according to the source scale factor information for better picture quality enhancement. In addition, embodiments provide source resolution detection that is minimally affected by video coding artifacts and superimposed content (e.g., graphics).

Abstract translation: 提供了用于视频内容源分辨率检测的实施例。 实施例使得能够测量视频内容源分辨率并且向图像质量（PQ）处理模块提供逐像素源比例因子测量的系统和方法。 利用源比例因子信息，PQ处理模块可以根据源比例因子信息进行动态调整（逐个逐个图像），以提高图像质量。 此外，实施例提供了受视频编码伪影和叠加内容（例如，图形）的影响最小的源分辨率检测。
