摘要： System and methodologies are provided herein for de-interlacing a video sequence. Various aspects described herein can utilize a motion adaptive video de-interlacing algorithm based on block-based texture classification and a multi-level decision hierarchy to interpolate missing fields of an interlaced video signal in the spatial and temporal domains. In accordance with various aspects described herein, respective blocks of an interlaced video sequence can be classified by a texture classifier as “textured” or “non-textured.” Based on this classification, one or more motion detection schemes can be utilized to determine whether the respective blocks are static or moving. Missing pixels from one or more blocks can then be estimated using the texture and motion classifications based on values of neighboring lines and/or pixels in the field from which the block was obtained as well as values of corresponding pixel locations in temporally adjacent fields.
摘要翻译：本文提供了用于对视频序列进行去隔行扫描的系统和方法。本文描述的各个方面可以利用基于基于块的纹理分类的运动自适应视频去隔行算法和多级决策层级来内插空间和时域中的隔行视频信号的丢失场。根据本文描述的各个方面，隔行视频序列的各个块可以由纹理分类器分类为“纹理”或“非纹理”。基于该分类，可以使用一个或多个运动检测方案来确定是否相应的块是静态的或移动的。然后可以使用基于纹理和运动分类的纹理和运动分类来估计来自一个或多个块的缺失像素，所述纹理和运动分类基于获得块的场中的相邻线和/或像素的值以及时间上相邻的场中的相应像素位置的值。
