23105 最后，在粒子滤波框架下，基于差别性局部区域测量构建了一种有效的目标跟踪算法。 at last, an effective and efficient tracker is designed based on the difference analysis and a simple update manner within the particle filter framework.
23106 实验结果表明，在复杂图像序列中，该算法实现了目标的准确跟踪，并在光照变化、旋转、缩放和遮挡等方面具有较好的效果。 Experimental results show that the proposed algorithm achieves better performance than traditional competing methods in various factors, such as illumination changes, part occlusion, scale changes and so on.
23107 针对老年人跌倒检测的准确性和实时性需求，该文首先建立了基于姿态角的活动描述模型，研发了集成加速度传感器、陀螺仪和蓝牙的活动感知模块，从而实时采集运动变化数据并使用蓝牙发送到智能手机。 According to the accurate and real-time requirement for fall detection. An activity model based on attitude angles is firstly established. A sensor board integrated with trial-axil accelerator and gyroscope is developed, which can capture the accelerations and angular velocities of human activities and transmit them to a smart phone by Bluetooth. Secondly, the three-dimensional attitude angle and acceleration signal vector magnitude are selected as features for fall detection.
23108 其次，选取姿态角及加速度信号向量模作为特征量，通过卡尔曼滤波对数据进行去噪与融合，并应用滑动窗口和 k-NN 算法实现了可实时感知老年人跌倒并报警的系统。 The collected data is preprocessed using Kalman filter to reduce noise and enhance the precision of attitude angle calculation. The k-Nearest Neighbor (k-NN) algorithm and appropriate sliding window are introduced to develop the fall detection and alert system.
23109 实验证明系统在二分类场景下的跌倒检测准确率为 98.9%，而敏感度和特异性分别达到 98.9%和 98.5%，验证了系统具有良好的实时性和较高的准确率。 At last, the experimental results show that the system discriminates falls from the activities of daily living with accuracy of 98.9%, while the sensitivity and specificity are 98.9%, and 98.5% respectively. It proves that the method has favorable accuracy and reliability.
23110 现代生活普遍压力较大，容易引起消极痛苦的应激，导致不良情绪甚至滋生各类慢性病。 In modern life, high stress causes negative emotions and even leads to various chronic diseases.
23111 心理专家需要了解个体的压力状态，从而开展对应性心理疏导和治疗。 Psychologists need to understand the stress state of the individual in order to facilitate the corresponding psychological treatment.
23112 传统心理学自评法存在一定的主观性；基于生理多导仪的压力状态评估法，受设备体积所限无法用于日常压力状态评估。 The traditional method of self-evaluation in psychology contains some subjectivity, while the method based on physiological polygraph can not be used in daily stress assessment because of the volume of equipment.
23113 针对上述问题，该文采用可穿戴式传感设备实时采集个体生理信号，利用心理和生理的伴生关系，对个体的心理压力进行长期实时评估。 For these reasons, a wearable device is used to collect the physiological signals and an assessment of the individual's stress is made according to the associated relationship between the psychological and physiological.
23114 同时通过蒙特利尔影像应激实验(MIST)诱发出被试平静、轻微及高度压力 3 种压力状态，此实验范式同时包含认知负荷精神压力因素与社会评价心理压力因素，与日常真实生活更为接近。 The Montreal Imaging Stress Task (MIST) is used to induce three states of no, moderate and high stress. The MIST includes both mental and psychosocial stress factors, which is more closing to a real-life condition. The experimental data are collected from 39 healthy subjects.
