  • 简介:我们描述在模糊集合和代数学的亢奋的结构之间的关系。事实上,这篇论文是Davvaz介绍在的想法的继续(模糊集合Syst,117:477-484,2001)并且Bhakat和Das在(模糊集合Syst,80:359-368,1996)。有一个珍视间隔的模糊集合的模糊间隔价值的伪巧合的概念被介绍,这是在模糊集合的一个模糊的点的伪巧合的自然归纳。由使用这个新想法,这个概念珍视间隔(α,β)一个亢奋的模块的模糊sub-hypermodules被定义。这最新定义珍视间隔(α,模糊sub-hypermodule是的β)平常的模糊sub-hypermodule的归纳。我们将学习如此的模糊sub-hypermodules并且考虑一个亢奋的模块的基于含意的珍视间隔的模糊sub-hypermodules。

  • 简介:为多看法录像编码的一个新奇颜色赔偿方法(MVC)被建议,它高效地与照相机的差异引起的颜色失配的存在利用在看法之间的会见相关性。一个颜色赔偿模型在红绿蓝隧道被开发然后为实际使用延长了到YCbCr隧道。一幅修改会见参考图画基于颜色赔偿模型被构造,它比原来的会见参考图画更类似于编码图画。而且,颜色赔偿因素能在编码器和解码器被导出,因此,没有另外的数据需要被传给解码器。试验性的结果证明建议方法改进MVC的编码效率并且维持好主观质量。
