23955 同时，由于节点间交换传递的译码信息都是基于 1 个比特位的二元信息，也非常便于硬件的设计与实现。 Moreover, all the decoding messages exchanged among the nodes are binary-based, which makes the presented algorithm convenient for the hardware implementations.
23956 视觉注意机制表明人眼趋向于关注感兴趣区域。 Human vision pays more attention to the interesting region than other areas.
23957 为了实现图像视觉增强，该文提出基于 2 维直方图分层差分表达理论的图像增强方法。 A method based on salient region detection for layered difference representation of 2D histogram is proposed to achieve visual enhancement.
