    Abstract: Systems and methods may provide for obtaining data associated with an image and using a plurality of threads in a graphics processor to conduct a single instruction multiple data (SIMD) scan of the data. Additionally, systems and methods may provide for generating a plurality of connection tables corresponding to the plurality of threads based on the SIMD scan. In one example, a plurality of threads in the graphics processor are used to conduct a single phase merge of the plurality of connection tables onto a global connected components labeling (CCL) table for the image.

    Abstract translation: 系统和方法可以提供用于获得与图像相关联的数据并且使用图形处理器中的多个线程来进行数据的单指令多数据(SIMD)扫描。 此外,系统和方法可以提供用于基于SIMD扫描生成与多个线程相对应的多个连接表。 在一个示例中,图形处理器中的多个线程用于将多个连接表的单相合并进行到用于图像的全局连接分量标签(CCL)表。

    Abstract: In accordance with some embodiments, connected-component labeling is performed in both the screen dimensions (which may be referred to as the x and y dimensions) and a depth dimension to label objects in a depth image. Then the contour of labeled blobs may be used to identify an object in the depth image. Using contours may be advantageous in some embodiments because it reduces the amount of data that must be handled and the extent of computations, compared to conventional techniques which use bit map based operations.
