色度

The color space based on the psychophysical experiments of human visual system is non-flat.

传统的色度学系统是建立在人类视觉系统的心理物理实验基础上的，共有基于实验的色标系统（如MUNSELL颜色体系）和基于实验的经验公式系统（如CIELAB，CIELUV体系）二类体系。

The images of ranbutan were obtained by CCD camera. Image processing algorithm of OSTU and area labeling were applied to 48 rambutan images in order to remove the images of background and stem, and the texture features of color and lustre were extracted. A multi-grade support vector machine was set up, and color and lustre features were the inputs of DAGSVM.

通过CCD采集红毛丹可见光图像，经OSTU分割算法来分割图像背景后，采用面积标记算法得到去除长穗梗区域的红毛丹图像；然后提取基于色度的红毛丹图像的彩色纹理特征，并用多分类支持向量机的模式识别方法来识别红毛丹色泽等级。

The adaptive single Gaussian modelis used in the stable region with gradual changes and the nonparametric model is usedin the dynamic region with jumping changes.A Generalized Agglomerative Scheme isused to merge the pixels in the Variable Region and fill the small interspaces.ATwo-Threshold Sequential Algorithmic Scheme is used to group the backgroundsamples of the Variable Region into distinct Gaussian distributions.

通过在色度和亮度空间对监控背景进行有效的区域分类，在变化小的稳定区域采用简单快速的自适应单高斯模型，在变化大的动态区域采用计算复杂而有效的非参数化模型。

A clear-cut way to resample is to interpolate the missing chroma values from their nearest neighbors by simple averaging.

一个简洁的再采样方法是从最邻近的像素上借助简单的平均化方法插值出缺失的色度值。

The result demonstrated that the chromaticity color of wastewater and COD were decreased after pretreatment, and biochemical effect was improved. It was the foundation of the secondary biological treatment and standard emission.

实验结果表明，预处理出水的色度、COD都有较高的去除，提高了废水的可生化性，为后续二级生物处理该种废水使其最终达标排放奠定了基础。

Utilizing contemporary design hallmarks of clean basic shapes and shades of primary colors the living room is a showplace.

运用现代设计干净基本的形状和主色色度，起居室非常值得一看。

The results Showed that the nascent MnO 2 is of quasi spherical particle with mean size of 250 nm;pH is the main factor affecting COD and color removal.

研究了新生态MnO2 对碱法麦草浆造纸黑液的COD和色度的去除效果及其主要影响因素，并探讨了MnO2 的作用机理。

It is pointed out that under the condition of the temperature of 1120℃, the reaction time of 16 mm and the carbon content of 27%, the metal transformation rate of sponge iron used for general metallurgy is up to 90%. But the optimal carbon content is 29% for iron sponge to treat DSD acid oxidation wastewater. Under condition of the wastewater's pH value of 3 to 5 and the reaction time of 40min, the removal rates of COD and color are 68% and 90%, respectively. The BOD/COD ratio is up to 0.425 when DSD oxidation acid water is treated with sponge iron.

研究表明：在配碳量27%、反应温度1160℃、反应时间16min的情况下，以铁泥为原料制备的常规海绵铁的金属化率可达90%以上；用于处理DSD酸氧化废水的海绵铁适宜配碳量为29%，用制备出的海绵铁处理DSD酸氧化废水，在pH值3~5、反应时间40min时，出水的COD去除率可达68%、色度的去除率达90%、可生化性指标BOD/COD提高到0.425。

The whole system was calibrated by standard lamp with the standard transferred from the national primary photometric and colorimetric standard.

系统量值传递是通过国家色度和亮度基准标准灯来完成的。

Choose two swatches at a slightly darker shade to the background colour and position the angle straight downwards.

选两个比背景色度稍深的样本将角度直接往下拉。
