摘要:

步态识别是近年来新兴的人体生物特征识别技术之一,它具有非侵入性的学习方法,可用于基于安全的目的。与其他生物计量学相比,步态分析具有一些特殊的安全特征。大多数生物识别技术使用基于序列模板的成分分析进行识别。与这些方法相比,我们提出了一种改进的步态识别技术,使用特征步态能量图像(GEI)。GEI步态表示包含了一个步态周期内每幅图像的全部信息,存储量少,处理速度低。由于一幅图像就足以存储GEI特征识别所需的信息,因此GEI特征的识别过程比其他任何特征都要简单。步态识别在识别过程中有一定的局限性,如视角变化,步行速度,衣服,携带负荷等,我们提出的方法在该文件中的识别性能与基于模板的特征提取,需要处理每一帧的周期。我们使用GEI,它提供了相对所有的信息,所有的帧在周期中,并导致更好的性能比其他功能的步态分析。

英文摘要:

Gait recognition is one of the most recent emerging techniques of human biometric which can be used for security based purposes having unobtrusive learning method. In comparison with other bio-metrics gait analysis has some special security features. Most of the biometric technique uses sequential template based component analysis for recognition. Comparing with those methods, we proposed a developed technique for gait identification using the feature Gait Energy Image (GEI). GEI representation of gait contains all information of each image in one gait cycle and requires less storage and low processing speed. As only one image is enough to store the necessary information in GEI feature recognition process is very easier than any other feature for gait recognition. Gait recognition has some limitations in recognition process like viewing angle variation, walking speed, clothes, carrying load etc. Our proposed method in the paper compares the recognition performance with template based feature extraction which needs to process each frame in the cycle. We use GEI which gives relatively all information about all the frames in the cycle and results in better performance than other feature of gait analysis.
