对比度

Results We extended the contrast of picture and to make obvious augmented effect in vision.

结果 拉大图像的对比度并在视觉上达到明显增强的效果。

In order to improve the energy efficiency and image contrast of liquid crystal display projector, a wide-angle and broadband optical thin-film polarizing beam splitter was designed.

A new kind of image adaptive contrast enhancement approach based on particle swarm optimization algorithm and incomplete Beta function is given.

将免疫粒子群优化算法和非完全Beta函数结合，提出了一种自适应图像对比度增强方法。

The results indicate that the signal contrast of image is increased with the birefringent filter.

实验表明，在光路中加入双折射滤光器，可以显著提高信号光的成像对比度。

The Leica is indeed fully usable at f/1.4 with a bitingly sharp center, a very good border/corner performance and very high contrast.

f/1.4 确实完全能用，中央的锐度惊人、边角表现非常好并且有很高的对比度。

Finally, display quality affected by the factors of brightness, contrast, ambient illuminance, screen glass transmission and black matrix of CRT are studied with the SQRI method.

It is seen here after bluing, which really makes the silver inlay work stand out in high contrast.

这是在这里看到后，发蓝，真正使银镶嵌工作的站出来，在高对比度。

It solves the imaging problem in great contrast. In chapter 2, the author deeply studies and analyzes the arithmetic of the method of Born approximation inversion and points out the limitations and disadvantage of the method. The good inverse results can be obtained in little disturbance by Born approximation.

本文提出的反演理论，考虑到散射序列中高阶项对成像结果的影响，在反演时利用逆散射序列中的高阶项以弥补散射场数据的丢失，使得在大扰动量的情况下同样能够实现界面位置和形态的精确成像，解决了大对比度情况下的成像问题。
