摘要： Various examples are disclosed herein that relate to staged element classification. For example, one disclosed example provides a method of classifying elements by forming elements for classification into a plurality of first-level sets in a first stage, generating primary groups within the first-level sets based on element similarity, forming a plurality of second-level sets from the first-level sets in a second stage, generating secondary groups within the second-level sets based on element similarity, and merging a plurality of the primary and/or secondary groups based on element similarity.
摘要翻译：本文公开了与分段元素分类相关的各种示例。例如，一个公开的示例提供了一种通过在第一阶段中形成用于分类为多个第一级集合的元素来对元素进行分类的方法，基于元素相似性在第一级集合内生成主组，形成多个第二级组，在第二阶段中从第一级集合的级别集合，基于元素相似性在第二级集合内生成二级组，并且基于元素相似性来合并多个主组和/或辅组。

摘要： A sprite generation method used in video coding generates a sprite from the video objects in the frames of a video sequence. The method estimates the motion (1200) between a video object in a current frame and a sprite constructed from video objects for previous frames. Specifically, the method computes motion coefficients of a 2D transform that minimizes the intensity errors between pixels in the video object and corresponding pixels inside the sprite. The method uses the motion coefficients from the previous frame (1206) as a starting point to minimizing the intensity errors. After estimating the motion parameters for an object in the current frame, the method transforms the video object to the coordinate system of the sprite. The method blends (1204) the warped pixels (1202) of the video object with the pixels at corresponding positions in the sprite using rounding average such that each video object in the video sequence provides substantially the same contribution to the sprite.
