Auto-measuring System of 3-Dimensional Human Body

To realize the automation of fashion industry measuring, designing and manufacturing, the auto-measurement of 3D size of human body is of great importance.The auto-measurement system of 3D human body based on Charge Coupled Devices ( CCD) and infrared sensors is presented in this paper. The system can measure the bare size of human body that excludes the effect of clothing quickly and accurately.     

葛洲坝下游中华鲟产卵场流场计算和分析

针对中华鲟面临的不良生态环境和正面临濒危的状况，运用水动力学的N—S方程和k-ε紊流数值模型，结合计算水气两相流的方法VOF（volume of finite），采用控制体积法离散计算区域，通过建立葛洲坝下游中华鲟产卵场的生态水动力学模型，来模拟葛洲坝下游不足5km江段的三维水流特征．并结合中华鲟的生态水力学特性（对流场改变的敏感性和选择性），分析中华鲟产卵繁殖的流场特性，以期为三峡水库优化调度提供理论依据和技术参数．     

Human Body Image Edge Detection Based on Wavelet Transform

Human dresses are different in thousands way. Human body image signals have big noise, a poor light and shade contrast and a narrow range of gray gradation distribution. The application of a traditional grads method or gray method to detect human body image edges can't obtain satisfactory results because of false detections and missed detections. According to the peculiarity of human body image, dyadic wavelet transform of cubic spline is successfully applied to detect the face and profile edges of human body image and Mallat algorithm is used in the wavelet decomposition in this paper.
