基于Land实验的可见红外伪彩色图像融合方法

由Land在研究人类视觉颜色恒定性现象时从所做的某个实验出发,通过对该实验中所用红、绿色滤波片的理想化假设以及光源的等能分布假设,并建立红外图像与红色透明片、可见光图像与绿色透明片的对应关系,得到Land实验启发下的新的伪彩色融合算法。通过与Toet伪彩色融合算法的结果比较,说明了该方法的有效性。进而借鉴Toet算法中强调图像特有成分的思想,使本算法输出更丰富、更逼近真实景物的色彩。

Land's experiment based false color fusion method for visual and infrared images

A new false color image fusion method was proposed based on Land's experiment on color constancy of human vision,which adopts an idealized hypothesis of the red filter and green filter,an equi-energy distribution hypothesis of the light source,and relates the infrared and visual images to the black-and-white transparencies resulting from the red and green filters of Land's experiment respectively.The method is illustrated to be effective after compared with Toet et al.'s fusion method.Its colorfulness is enhanced and its appearance is more realistic through assigning the difference between the source images to the blue channel to underscore the characteristic components of the individual images.
