亮度范围

高动态范围（HDR）图像属于场景参考编码图像，能够再现人眼视觉可感知的真实场景亮度范围。

High Dynamic Range ( HDR ) image belongs to scene referred encoding image , and they can reappearance the luminance range of the natural world which human vision can perceive .

同态滤波是一种将亮度范围压缩和对比度增强的频域处理方法。

Homomorphic filtering is a frequency domain operation to compress image light area and enhance contrast .

共焦显微图象如荧光染色细胞核图象，往往是一种比较模糊的图象，并且亮度范围大，灰度均匀度也较差。

In most of cases , the laser scanning confocal microscopy images , such as fluorescence stained biomedical nuclei , are blurred and have a wide range of brightness and poor intensity homogeneity .

高动态图像是一种亮度范围非常大的特殊图像，它最大的特点是其存储的图像亮度信息与真实场景的辐射度呈线性关系。

High Dynamic Range Image ( HDRI ) is a special kind of image format whose scope for luminance is quite large , with its most important characteristic being that : luminance information stored in an HDRI is linearly correlated to true radiance sensed in real scenes .

我们还讨论了在GLC的亮度监测范围内树图及一圈修正后的总截面随质心能量的变化关系。

We discussed the relations between the cross-sections in tree level ( and one-loop corrected cross sections ) and center-mass energy in the luminosity measuring ranges of GLC .

具有噪音小，功率大，在亮度控制范围内高效率低损耗。

With a small noise , power , brightness control in high-efficiency low-loss .

现实生活中，人眼的观测范围很广，但对于普通数码相机来说，受硬件设备的限制，感光范围是有限的，当场景亮度跨度范围大时，无法在同一张照片上记录所有光强信息。

In real life , the human eye has a wide observing range . However , for ordinary digital cameras affected by the hardware devices , sensitivity range is limited .

由于彩色印片材料只能再现有限范围的亮度，故景物的亮度范围对彩色负片十分重要。

The brightness range of the scene is very important for negative films since color print material can only reproduce a limited brightness range .

而口腔通常都处于阴影中，因此口腔像素占有的亮度值都属于低灰度亮度范围。

And the interior is usually in the shadow , so the pixels of this part are low - intensity .

拖动垂直整体亮度增加的地区之间的选择曲线点，并拖动选择横向或颜色的亮度范围，是改变了曲线。

Dragging them vertically increased the overall brightness of the areas between the selected curve points , and dragging horizontally selects the brightness or color range that is changed by the curve .

除去低亮度区域内白噪声的影响后，以对数函数为权值，在考虑了一定亮度范围内的像素分布后，提出了一个用于评价颗粒运动剧烈程度的指数。

After eliminating the influence of noise and taking consider of the gray level of pixels within certain range , a weight factor based on logarithm function was introduced to evaluate the intensity of particles ' movement .

阐述了亮度与视亮度的关系，分析了视亮度的模型公式、背景视亮度、视亮度边界的适用范围和条件，并对照明光环境的视亮度均匀性以及等效亮度进行了研究。

It presents relationship between luminance and brightness , analyses model formula of brightness , background bright-ness , suitable scope and condition of brightness edge . It also discusses brightness uniformity and equivalent luminance .
