对比度

There has some intuitionist noise which declines the quality of image in the medical digital image. So we need to eliminate noise from image. To improve contrast sensitivity, display the illegible and low contrasted detail of image, We need to enhance image.

医学图像中存在着一些直观的噪声，使图像的质量下降，因此需要对图像进行去噪，为了提高图像的对比灵敏度，显示图像中较模糊、对比度差的细节，还需要对图像进行增强处理。

Overall, the JVC looks to be the higher contrast of the two pictures.

总的来说，JVC公司看起来是两个图片更高的对比度。

High key with a bit more contrast to focus on eye area.

最关键的是用稍高的对比度，使眼部区域成为关注焦点。

Firstly,the color image is sharpen by Unsharp Mask to extract detail information,and color scaling is used to strength contrast degree.Secondly,stroke direction is generated by the method of vector field.Finally results of the pencil-drawing are gained by the line integral convolution algorithm.

首先对用户输入的图像进行Unsharp Mask锐化提取细节信息，并进行颜色放大处理以增强对比度，然后采用基于点的向量场技术生成笔画方向，最后应用线积分卷积得到具有素描风格的结果图像。

Literal facial expression and setting are lubricious when designing between best can form bright contrast.

设计的时候文字颜色与背景色之间最好能形成鲜明的对比度。

You may also rotate selected curve points, increasing local contrast and color variation.

您可能还轮流选定的曲线点，增加当地的对比度和颜色变化。

The results shows that the effect of the speckle noise can be suppressed by displaying OCT images in the logarithmic scale and the speckle properties are correlated with the scattering properties of the tested sample. Additionally, it is shown that OCT with NA = 0.25 has a lower speckle noise and a larger length of single scattering range.

结果显示采用对数表示可以抑制散斑噪声对图像对比度的影响，而且此时的散斑特性与介质的散射特性相关联，另外，采用较高数值孔径显微物镜可以抑制散斑噪声以及增大成像深度。

Not only is contrast outstanding, but the AE3000 has an excellent range of lumen output.

不仅是杰出的对比度，但AE3000有极好的一系列流明输出。

Contrast on the screen was again improved, with virtually no cost in lumen output.

在屏幕上再次提高对比度，几乎没有流明输出的成本。

In gray mode, it can avoid the decrease of contrast caused by traditional luminance enhancement method.

在灰度模式下，该算法可以避免传统处理带来的对比度减小，从而保留更多的暗部细节。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
