Several image fusion algorithms, such as contrastmodulation fusion, false color fusion and wavelet transform fusion have been adopted to realize the fusion of visual and infrared images.
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.
