Abstract
Embodiments of the present invention provide a method and an apparatus for assessing video quality. The method includes: determining an actual quantization parameter and a critical quantization parameter of the target video according to a target video, where the critical quantization parameter is a maximum quantization parameter of the target video in a case in which a distortion is not evidently identifiable by human eyes; and determining quality of the target video according to the actual quantization parameter and the critical quantization parameter. According to the method and apparatus of the present invention, a critical quantization parameter of a target video is determined, and the actual quantization parameter is compared with the critical quantization parameter, which can accurately determine whether subjective quality of the target video changes strictly monotonically relative to the used actual quantization parameter, so that the video quality can be assessed accurately.
