In this study, we present a new andinnovative framework for acquiring high-qualitySVBRDF maps. Our approach addresses the limitations of the current methods and proposes a newsolution. The core of our method is a simple hardwaresetup consisting of a consumer-level camera, LEDlights, and a carefully designed network that canaccurately obtain the high-quality SVBRDF propertiesof a nearly planar object. By capturing a ﬂexiblenumber of images of an object, our network usesdifferent subnetworks to train different property mapsand employs appropriate loss functions for each ofthem. To further enhance the quality of the maps, weimproved the network structure by adding a novel skipconnection that connects the encoder and decoder withglobal features. Through extensive experimentation usingboth synthetic and real-world materials, our resultsdemonstrate that our method outperforms previousmethods and produces superior results. Furthermore,our proposed setup can also be used to acquire physicallybased rendering maps of special materials.

A method is introduced for handiing-large linear system whose characteristic is that given the values of the nontheic variables, those of the basic ones can be readily worked out with the help of a so-called adjoint canonical form instead of depending on the original one. ms method mey there fore be applied advantagequsly to a variety of large-seale linear system problem, for instunce,the optimal multi-circulation problem.

Acoustic vector sensor simultaneously, colocately and directly measures orthogonal components of particle velocity as well as pressure at single point in acoustic field so that is possible to improve performance of traditional underwater acoustic measurement devices or detection systems and extends new ideas for solving practical underwater acoustic engineering problems. Although acoustic vector sensor history of appearing in underwater acoustic area is no long, but with huge and potential military demands, acoustic vector sensor has strong development trend in last decade, it is evolving into a one of important underwater acoustic technology. Under this background, we try to review recent progress in study on acoustic vector sensor signal processing, such as signal detection, DOA estimation, beamforming, and so on.

The 3D shape of the human body is useful for applications in fitness, games and apparel. Accurate body scanners, howev- er, are expensive, limiting the availability of 3D body models. In this paper, we focus on the human body 3D modeling using one Kinect sensor modeling method. To get the human body model fast, three steps in rapid modeling of the human body are carried out. Firstly, according to anthropometric parameters, the standard model is parameterized; Secondly, the Kinect depth image of the human body model is gotten through, then, by using the PCL library the point cloud data is processed and matched, and the human body model is optimized; Finally, the realistic human body model is obtained with the rapid integration of the standard model and PCL library.

广义重心坐标已被广泛应用于三维网格模型的编辑与变形中,而cage是广义重心坐标编辑的重要载体.为此提出一种全自动的cage生成方法.首先对给定三维网格模型做适当简化,然后建立简化网格的距离场,再抽取指定距离值的offset网格,最后根据指定顶点数或误差阈值简化offset网格,从而得到该网格模型的等距cage.其中,最耗时的距离场生成过程可以通过GPU加速使得算法接近实时.实验结果表明,文中方法生成的等距cage能很好地应用于广义重心坐标的网格编辑中.
