提出了一种基于3D体感机Kinect的图像处理手势识别算法,通过深度图像和骨骼图像的方法实现动态手势识别。首先在Kinect提供的骨骼图像中20个骨点中,选取2个离手部最近的骨骼点,通过追踪这两个骨骼点的位置来实现对手部的追踪,再通过判断手部的深度(即其相对于摄像头的距离)的变化来实现动态手势识别。 相似文献

当前方法对动态孤立手势的识别,过程复杂、成本高,动态手势的移动轨迹易受到外界环境的干扰、识别准确率低.提出了基于Kinect的动态孤立手势识别方法,利用Kinect传感器获取动态手势信息,对人体手部进行实时、准确的定位跟踪,并对手部图像进行平滑去噪处理,提取动态手势轨迹的特征;引入隐马尔可夫模型(HMM)对动态孤立手势及手部运动轨迹的样本集进行有效训练,最终实现动态孤立手势的精确识别.实验证明提出的方法在噪声干扰和光线缺失的环境下,对动态孤立手势仍具有较高的识别率,鲁棒性强. 相似文献

The article describes a model representation of radar probing data in form of a mixture of background and target samples, which is the sum of two random variables with very different parameters. For model development we research the behavior of the central moments of the distribution mix without assuming the distribution law form. An example it is described the detection of the signal at the output of compression system of chirp ionosonde. 相似文献

Assuming that visual responses are due to the action of particles on the membrane of the visual cells, the stochastic variability of the response should be a function of the number of particles producing it. Quantitative predictions can be made with the aid of a model proposed in previous articles. It is found that responses produced in visual cells of Limulus by absorption of a single photon have the stochastic properties which would be expected if the response to one photon were brought about by 25 particles. It is concluded from this that the processes leading to visual responses produce multiplication of particles. The effects of temperature and of metabolic poisons suggest that these processes are of chemical nature. 相似文献

The temperature dependence of refractive index of polymer films was determined for a number of slab waveguides by a grating coupling method. This dependence was examined as a function of parameters such as molecular weight and glass transition temperature of the polymer. Temperature-induced changes in N TE-N TM , N being the effective index, were studied systematically for different slab waveguide compositions. It is shown that with proper device design and choice of polymeric materials, thermal effects can be reduced 相似文献
