【摘要】 针对θ调制多光谱照相,提出了一种构造数字滤波模板进行解码的方法,将CCD获得的编码图像直接解码获得数字图像。讨论并模拟了解码单波段图像在RGB颜色空间、IHS颜色空间以及L*a*b*颜色空间的假彩色融合,实验结果表明,对于θ调制解码图像,基于L*a*b*颜色空间的HLC融合法目标与背景色彩反差最大,目标识别效果最好。更多还原

【Abstract】 Here we put forward a decoding method for θ modulated multi-spectral photography by constructing a digital wave filtering template and get the three-band gray images.The pseudo-color fusion methods of three band decoded images based on RGB color space,IHS color space,and L~a~b~ color space are discussed respectively.According to the simulated experiment,the HLC pseudo-color fusion method based on L~a~b~ color space can get the best detection result with the largest color difference between target and background.更多还原
