| 摘 要： | 提出了基于lαβ颜色空间变换和小波包变换的红外中波细分波段图像的伪彩色增强方法.利用lαβ变换将两个细分波段RGB彩色映射的伪彩色图像的颜色和亮度信息分离,通过二维小波包变换得到两个细分波段的融合图像,将融合图像和颜色信息经过lαβ逆变换形成伪彩色增强图像.实验结果表明,同简单彩色映射图像相比,伪彩色增强图像的局部标准偏差和局部熵都有增加,从而使图像具有更好的感知效果.

| Abstract: | Pseduo-color enhancement method of sub-band images of mid-wave infrared was presented based on both lαβ color space transform and wavelet packet transform. The color and luminance information of pseudo-color image obtained by RGB color mapping were separated by using lαβ color space transform. And the luminance part was replaced by the image fused from two sub-band images by wavelet packet transform, then pseudo-color enhancive image was obtained after inverse lαβ color space transform. The experimental results show that the local standard deviation and local entropy of enhancive image are increased by comparing with simple color mapping image, and the image enhancing has good perceptive effect. |
