Several image fusion algorithms, such as contrast modulation fusion, false color fusion and wavelet transform fusion have been adopted to realize the fusion of visual and infrared images.
采用了几种图像融合算法如对比度调制融合、伪彩色融合和小波变换融合法，实现了对红外和可见光图像的融合。
Increases both in image contrast and in image color are completed by duplicating ERS image, filtering and grating modulation.
利用该方法对资源卫星图片世行翻拍、滤波和光栅调制，实现图象的反差增强和假彩色增强。
The simulations show that more amplitude modulations and phase perturbations lead to lower contrast of the compressed pulse, and bigger modulation cycle results in wider pre-pulse width.
结果表明：啁啾光脉冲的振幅调制深度和相位扰动深度越大，则压缩后的光脉冲对比度越小；啁啾光脉冲的振幅调制周期和相位扰动周期越小，则压缩光脉冲的预脉冲宽度越大。
Then, the modulation contrast was selected to describe the intensity of grayscale distortion, and the factors of the contrast change were analyzed.
然后，选取调制对比度描述灰度畸变的剧烈程度，分析了引起对比度变化的因素。
Also, computer simulation is conducted to work out the contrast curve of scanning spots and the offset voltage across the modulation unit of the optical phased array.
最后通过计算机模拟计算，得出扫描点的对比度曲线以及相控阵调制单元上所加的补偿电压。
In contrast, 8-psk modulation implements a linear mode in which a time-varying amplitude is output from the pa as measured by power versus time during the useful part of the burst.
与此相反的是，8 - PS K调制方式实现线性模式，其中在脉冲串的有用部分期间，功率放大器发射的功率幅度随着时间而变化。
