58519 在真实的家居环境中对该系统进行实验，平均识别率可达到 96.4% . Exper?iment with the system in a real home environment shows the average recognition rate can reach 96. 4% .
58520 针对 EGBIS 分割算法中的过分割问题，提出了一种基于超像素的 graph-based 图像分割算法 SGBIS.首先，对图像进行基于简单线性迭代聚类( SLIC) 的超像素预分割; As graph-based algorithm is inclined to over-segment，a new graph-based image segmentationalgorithm based on superpixels called superpixel graph based image segmentation ( SGBIS) was proposedand simple linear iterative clustering ( SLIC) superpixels segmentation was employed as pre-segmenta?tion.
58521 然后以每个超像素作为节点构造带权无向图，以相邻超像素颜色平均值的欧式距离作为图中边的权值; Then，the weighted undirected graph regarding superpixels as nodes was constructed，the Euclideandistance of adjacent superpixels’average color is used as the weight.
58522 最后利用基于图的算法合并超像素得到分割结果. Finally，the segmentation resultsare obtained by merging superpixels based on graph-based algorithm.
58523 用 VI、PＲI 和 F 值 3 个指标分析了算法性能，结果表明，新算法可以得到更为理想的分割效果; Three indexes variation of informa?tion ( VI) ，probabilistic rand index ( PＲI) and F-measure are introduced to evaluate algorithm. Experi?ments show that it can get better segmentations.
58524 引入交互分割区域合并，也可满足用户图像分割的需求. An interactive region merging interface is also intro?duced，which could meet users need very well.
58525 稀疏码分多址接入( SCMA) 方案映射矩阵维度太小时，短环和规则度分布的 SCMA 映射矩阵与存在远近效应的环境不能很好地匹配，为此，提出一种新型的非正交多址接入方案———低密度叠加编码调制( LDSM) . There may exist short cycles if the matrix dimensions of sparse code multiple access ( SCMA)are small，and the regular mapping matrix of SCMA doesn’t take near-far effect into consideration. Therefore，a novel uplink non-orthogonal multiple access scheme named low density superposition modu?lation ( LDSM) scheme is proposed to construct a sparser and irregular mapping matrix.
58526 该方案设计了更加稀疏的非规则度分布映射矩阵，带来分集增益和编码增益，提高整体方案性能的同时，对边缘用户的性能也有所提高. The proposedscheme can improve the overall performance and the edge users’performance for it can get diversity gainand coding gain.
58527 在独立瑞利衰落信道下，通过平均互信息的分析，从理论上证明了 LDSM 方案较 SCMA 方案有一定的信噪比增益. The analysis of the average mutual information demonstrates LDSM can get signal tonoise ratio ( SNＲ) gains over SCMA in theory.
