一种基于多模式融合的多视点图像颜色校正方法

针对各种多视点成像系统中视点图像颜色不一致的问题,提出了一种基于多模式融合的多视点图像颜色校正方法.该方法通过定义四种通用的线性和非线性校正模式,首先对输入的源图像和参考图像进行视差估计,以视差估计得到的匹配块作为样本,然后对样本分别用四种校正模式进行训练,得到各种模式的校正参数,最后基于最小均方误差准则对各种校正模式进行融合,得到最终的校正图像.实验结果表明,该方法能实现参考图像与校正图像的最小均方根误差,且具有较好的校正效果.

Viewing 3D TV over two months produces no discernible effects on balance,coordination or eyesight

With the rise in stereoscopic 3D media, there has been concern that viewing stereoscopic 3D (S3D) content could have long-term adverse effects, but little data are available. In the first study to address this, 28 households who did not currently own a 3D TV were given a new TV set, either S3D or 2D. The 116 members of these households all underwent tests of balance, coordination and eyesight, both before they received their new TV set, and after they had owned it for 2 months. We did not detect any changes which appeared to be associated with viewing 3D TV. We conclude that viewing 3D TV does not produce detectable effects on balance, coordination or eyesight over the timescale studied.

Practitioner Summary: Concern has been expressed over possible long-term effects of stereoscopic 3D (S3D). We looked for any changes in vision, balance and coordination associated with normal home S3D TV viewing in the 2 months after first acquiring a 3D TV. We find no evidence of any changes over this timescale.

Thermodynamic and ab initio investigation of the Al–H–Mg system

A coupled ab initio and thermodynamic study of the Al–H–Mg system has been carried out and a self-consistent thermodynamic database has been obtained. Magnesium alanate Mg(AlH₄)₂, a candidate material for hydrogen storage, has been included into the database. According to Density Functional first principles calculations, the alanate is an insulator and its thermodynamic properties have been obtained at room temperature. This compound has been found metastable at 298.15 K and 1 bar. The alanate has been found thermodynamically stable only at high pressure when the formation of the binary β-MgH₂ phase is neglected. A reassessment of thermodynamic parameters of the liquid phase in the binary Mg–H system has also been carried out in order to be consistent with the Al–H system. The present results can reproduce reasonably well the available experimental data.
