METHOD AND APPARATUS OF CONTENT ADAPTIVE DETAILING FILTERING FOR DIGITAL PICTURES
Abstract:
According to one embodiment, a method is disclosed. The method includes receiving video data performing pre-filtering on the data, performing content analysis is applied to identify an area of the data, applying a two-dimensional (2-D) 2nd gradient operation to extract a high frequency component and normalizing the high frequency component related to high frequency information from a previous picture.
Abstract(Chinese):

根据一个实施例，公开了一种方法。 该方法包括接收对数据执行预滤波的视频数据，执行内容分析以识别数据的区域，应用二维（2-D）第二梯度操作来提取高频分量并使高标准化 与前一图像的高频信息相关的频率分量。
