Weight measurement using image-based pose analysis

Image-based gait analysis as a means of biometric identification has attracted much research attention. Most of the existing methods focus on human identification, posture analysis and movement tracking. There have been few investigations on measuring the carried load based on the carrier＇s gait characteristics by automatic image processing. Nevertheless, this measurement is very useful in a number of applications, such as the study of the carried load on the postural development of children and adolescence. In this paper, we investigate how to automatically estimate the carried weight from a sequence of images. We present a method to extract human gait silhouette based on an observation that humans tend to minimize the energy during motion. We compute several angles of body leaning and determine the relationship of the carried weight, the leaning angles and the centroid location according to a human kinetic study. Our weight determination method has been verified successfully by experiments.     

学年学分制模式下的高校学生工作探索

我国目前大多数高校采用学年学分制,与学年制和完全学分制不同,它以学分为计量单位,按学年或学期作为结算时段确定学生的降级和退学标准,有相对固定的修业年限。文章对该模式下的学生工作进行初步探讨,提出了进一步完善辅导员制度、加强班集体建设等系列措施。     

Perceptual learning of dot pattern

Dot pattern is a type of pattern defined by specific spatial relationship among some dots. As a compensation for concrete and meaningful visual stimuli, meaningless dot pattern can be used as stimuli in learning tasks. We performed an experiment for exploring the perceptual learning process of dot pattern against random-dot background. Participants were required to learn two types of dot patterns (9-dot and 11-dot). They were assigned to two groups: participants in Group 1 learned 9-dot pattern first and 11-dot pattern later, while those in Group 2 learned 11-dot pattern first and 9-dot pattern later. The results showed that participants could acquire the spatial relationship of dot pattern through perceptual learning in relatively short learning time. In comparison with 9-dot pattern, learning time of 11-dot pattern was slightly longer and its accuracy rate lower, but there was significant positive transfer effect from 11-dot pattern learning to 9-dot learning.     

计算机辅助设计与分析多模圆锥喇叭天线

多模圆锥喇叭天线是一种应用较广的新型高效率喇叭天线,合理设计的多模圆锥喇叭天线,它的方向图可以得到很好的等化性能,所以被广泛应用于反射镜初级馈源和实验室标准天线等。但是,设计的多模圆锥喇叭波束宽度(-3dB)较窄,喇叭口径在5个波长左右。本文在传统设计方法的基础上,对多模圆锥喇叭天线采用计算机辅助设计,避免了人工计算带来的误差,而且设计范围更加灵活。文章较详细地介绍了设计方法和计算框图,最后给出了分析实例,并具体设计了一种较宽波束的多模圆锥喇叭天线,理论计算和实测结果非常一致,证明了这种方法是行之有效的。

用于分布式识别的语音参数的提取和性能分析

主要研究用于分布式语音识别(DSR)的语音参数的提取方法以及参数性能分析。以前所用到的语音参数大部分是LPC倒谱参数,但其抗噪声性能较差。文中主要讨论了MEL倒谱参数,并在移动通信环境下,比较了两者的性能。

论铁凝对女性模仿性生存的女性叙事

铁凝一直自我定位于“第三性”写作,可是读罢她的大多数小说之后,却发现了她不同的小说中存在着一个共同的女性生存模式——模仿。这种模仿与生存处境的弱势有关,模仿中的焦虑与性别弱势有关。铁凝的“第三性”声明是作家刻意的性别遮蔽。     

统计模式识别的研究

模式识别的基本目标就是在有监督和无监督的情况下进行分类,在模式识别的各种模型中,基于统计的方法已经被广泛的研究并应用于实际.一些新的技术和方法的引入（神经网络和支持向量机方法）也促进了该领域发展,文章研究了基于统计的模式识别的进展情况,给出了模式识别的概念、原理、方法并对各种方法进行了相关的评述.
