In recent years,gait-based emotion recognition has been widely applied in the field of computer ***,existing gait emotion recognition methods typically rely on complete human skeleton data,and their accuracy significantly declines when the data is *** enhance the accuracy of gait emotion recognition under occlusion,this paper proposes a Multi-scale Suppression Graph ConvolutionalNetwork(MS-GCN).TheMS-GCN consists of three main components:Joint Interpolation Module(JI Moudle),Multi-scale Temporal Convolution Network(MS-TCN),and Suppression Graph Convolutional Network(SGCN).The JI Module completes the spatially occluded skeletal joints using the(K-Nearest Neighbors)KNN interpolation *** MS-TCN employs convolutional kernels of various sizes to comprehensively capture the emotional information embedded in the gait,compensating for the temporal occlusion of gait *** SGCN extracts more non-prominent human gait features by suppressing the extraction of key body part features,thereby reducing the negative impact of occlusion on emotion recognition *** proposed method is evaluated on two comprehensive datasets:Emotion-Gait,containing 4227 real gaits from sources like BML,ICT-Pollick,and ELMD,and 1000 synthetic gaits generated using STEP-Gen technology,and ELMB,consisting of 3924 gaits,with 1835 labeled with emotions such as“Happy,”“Sad,”“Angry,”and“Neutral.”On the standard datasets Emotion-Gait and ELMB,the proposed method achieved accuracies of 0.900 and 0.896,respectively,attaining performance comparable to other ***,on occlusion datasets,the proposedmethod significantly mitigates the performance degradation caused by occlusion compared to other methods,the accuracy is significantly higher than that of other methods.

目的初步探讨FibroScan联合GGT/PLT比值(GPR)预测慢性乙型肝炎(CHB)患者肝纤维化分期的诊断价值。方法选取广州市第八人民医院2012年1月-2016年12月肝活组织检查诊断为CHB患者278例,分析GPR、FibroScan以及二者联合诊断预测纤维化分期(F0～F4)的价值。非正态分布的计量资料多组间比较采用Kruskal-Wallis H检验,进一步两两比较采用MannWhitney U检验。相关性分析采用Spearman相关系数。受试者工作特征曲线下面积(AUC)评估肝纤维化分期。结果以肝活组织检查作为金标准,F1～F4期患者分别有50、104、92和32例。随着肝纤维化分期加重,FibroScan检测肝硬度值(LSM)逐渐升高(P值均<0. 05); GPR在肝纤维化F1、F2、F3期逐渐升高(P值均<0. 05)。GPR、FibroScan均与肝纤维化呈正相关(r值分别为0. 419、0. 481,P值均<0. 001); GPR与FibroScan呈正相关(r=0. 436,P <0. 001)。FibroScan与GPR联合预测进展期肝纤维化(≥F3)的诊断效能优于单一FibroScan(AUC:0. 793 vs 0. 739,Z=3. 044,P=0. 002)或GPR(AUC:0. 793 vs 0. 740,Z=2. 389,P=0. 037);二者联合预测明显肝纤维化(≥F2)的诊断效能优于单一GPR(AUC:0. 782 vs 0. 714,Z=2. 130,P=0. 033)。结论 FibroScan与GPR联合诊断对于预测CHB进展期肝纤维化(≥F3)具有优势,初步认为可提高诊断效能。
