invariability

It found invariability is one of the painting-language s attribute as variability.

把水彩画的整个发展过程作为研究对象,从工具材料、表现技法和审美理念三个层面分析水彩画的本体语言,发现本体语言既有恒定性的一面,也有变化性的一面。

In order to improve the accuracy of colorimetric characterization of liquid crystal display(LCD),a piecewise partition model(PP model) was proposed concerning the LCD s poor performance of constant channel chromaticity and channel independence.

为了提高液晶显示器(LCD)颜色特征化精度,根据液晶显示器色品恒定性和通道独立性较差的特点,提出了分段分空间模型。

By setting the brightness and contrast of a Neso color display to 20%,50%,80% and 100% respectively(totally 16 groups),the black point luminance,white point luminance,tune reproductive curve(TRC),channel additivity,color gamut and the constant channel chromaticity under each setting were measured and compared in detail.

将Neso彩色显示器的亮度和对比度分别设置为最大值的20、50、80和100%共16种组合,详细地测试和比较了每种设置下显示器的黑点亮度、白点亮度、阶调再现曲线(TRC)、通道可加性、色域和色品恒定性等颜色特性,实验结果表明,亮度设置对黑点亮度影响明显,对比度设置主要影响的白点亮度,黑点对通道可加性、色域和色品恒定性影响很大。

A new false color image fusion method was proposed based on Land s experiment on color constancy of human vision,which adopts an idealized hypothesis of the red filter and green filter,an equi-energy distribution hypothesis of the light source,and relates the infrared and visual images to the black-and-white transparencies resulting from the red and green filters of Land s experiment respectively.

由Land在研究人类视觉颜色恒定性现象时从所做的某个实验出发,通过对该实验中所用红、绿色滤波片的理想化假设以及光源的等能分布假设,并建立红外图像与红色透明片、可见光图像与绿色透明片的对应关系,得到Land实验启发下的新的伪彩色融合算法。
