Method and system for calculating blur artifacts in videos using user perception threshold
Abstract:
A method and system for calculating a blur artifact in a video are disclosed. The video includes a series of frames captured at a predefined interval of time. The frames include one or more pixels. Calculating the blur artifact in the video includes identifying a focused area in a set of frames. Further, edges are detected in each of the frames. Furthermore, the blur artifact is calculated as a ratio of number of blurred pixels and total number edge pixels.
Abstract(Chinese):

公开了一种用于计算视频中的模糊伪影的方法和系统。 视频包括以预定的时间间隔捕获的一系列帧。 帧包括一个或多个像素。 计算视频中的模糊伪像包括识别一组帧中的聚焦区域。 此外，在每个帧中检测边缘。 此外，模糊伪像被计算为模糊像素数和总数边缘像素的比率。
