从最早的单音到现在流行的和弦, 手机铃声的发展可以说是一日千里。谈到手机铃声,不免让人想到三星手机炫耀、动听的铃声效果,是否让你梦寐以求但却不知如何得到呢?今天笔者就教大家制作个性化的64和弦人声MMF铃音。
三维真实感图形是科学可视化、计算机动画和虚拟现实的关键技术之一.介绍了利用OpenGL绘制三维立体图形的方法,充分利用OpenGL的库函数进行了三维场景的绘制、渲染和纹理映射,绘制了真实的三维立体图形,并提供了一些从不同侧面和角度观察所绘图形的方法.软件在Winows2000/VisualC++6.0下开发,采用窗口的切分功能扩大视图范围,可提供不同的颜色背景和不同的视角进行观察,也可以对图形进行
Plants become photosynthetic through de-etiolation, a developmental process regulated by red/far-red light-absorbing phytochromes and blue/ultraviolet A light-absorbing cryptochromes. Genetic screens
计算机多媒体技术应用于电厂三维设计,是近年发展起来的新技术。在宣威电厂五期扩建工程设计中,应用三维模型制作、动画漫游及后期多媒体合成等技术,取得了较好效果。
By introducing the homogenous coordinates, degree elevation formulas and combinatorial identities, also by using multiplication of Bernstein polynomials and identity transformation on equations, this
Image segmentation is a necessary step in image analysis. Support vector machine (SVM) approach is proposed to segment images and its segmentation performance is evaluated. Experimental results show t
This paper presents a basis for the space of hyperbolic polynomials Γm=span{1, sht, cht, sh2t, ch2t, …, shmt, chmt} on the interval [0,α] from an extended Tchebyshev system, which is analogous to the
本文介绍了最新研制成功的一套大型人脸识别系统。文中给出了系统的结构、人脸识别算法、性能指标以及人脸识别示例并提出了奥运会使用人脸识别系统的设想。
Intertidal seaweeds experience periodical desiccation and rehydration to different extents due to the tidal cycles and their vertical distributions. Their photosynthetic recovery process during the re
夜间低温导致海桐和榕树叶片光系统II(PSII)最大光化学效率(Fv/Fm)、PSII光合电子传递量子效率(ΦPSII)、天线转化效率(Fv/Fm)、非光化学猝灭系数(NPQ)降低,其后日间光照先引起海桐叶片Fv/Fm、ΦPSII、Fv/Fm稍微降低,其后又逐渐得到恢复,但NPQ却表现出相反趋势;夜间低温及随后的日间光照并未对海桐叶片光化学猝灭系数(qP)和初始荧光强度(Fo)产生影响。夜间低温后
