用于统一显著图编码的方法和设备
摘要：
提供了用于统一显著图编码的方法和设备。一种设备包括：视频编码器(400)，针对画面的至少一部分对变换系数进行编码。变换系数是使用多个变换获得的。基于统一规则为变换系数产生一个或多个上下文共享图。所述一个或多个上下文共享图用于提供至少一个上下文，所述至少一个上下文在从多个变换中的至少两个不同变换获得的变换系数中的至少一些之间被共享。
摘要（英）：

Methods and apparatus are provided for unified significance map coding. An apparatus includes a video encoder for encoding transform coefficients for at least a portion of a picture. The transform coefficients are obtained using a plurality of transforms. One or more context sharing maps are generated for the transform coefficients based on a unified rule. The one or more context sharing maps are for providing at least one context that is shared among at least some of the transform coefficients obtained from at least two different ones of the plurality of transforms.
