多媒体人机交互界面视觉精度评估仿真

摘要

对多媒体人机交互界面的视觉精度进行评估,能够提高多媒体人机交互界面的用户体验.对人机交互界面视觉精度评估,需要计算结构信息强度,获取评估值,完成人机交互界面视觉精度的评估.传统方法首先检测图像质量,计算精度评分值,但忽略了获取评估值,导致评估效果不理想.提出多媒体人机交互界面视觉精度评估方法,结合Harris特征点检测算法,提取人机界面视觉显著性区域,计算界面子图像平均结构信息能量及结构信息强度,获取评估值.仿真测试结果表明,所提方法大大提高了多媒体人机交互界面的用户体验.%Traditional evaluation method of vision precision of multi-media human-computer interface always ignores acquisition of evaluation value,which leads to unsatisfied estimation effect.In order to solve the problem,a new evaluation method is proposed.Integrated with algorithm of Harris feature point detection,vision salient region of human-computer interface is extracted.Average energy and strength of structural information of interface sub-image are calculated.Thus,evaluation value is acquired.Simulation results shows that the proposed method improves user experience of the multimedia human-computer interface by a large margin.
