新标准需同时记录分辨率和测量出的“调制对比度”(Contrast modulation)值。调制对比度指的是相间黑白线的亮度变化值,调制对比度达到50%以上,就是判断是否达到指定分辨率的基准。

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。
