Colormap Development for Night Vision from Synthetic Imagery

Abstract

We presented a method for colorizing fused imagery using a synthetic image as the color source. Imagery acquired at night from two sensors with different spectral bands were fused into a single image. We used a color transfer method based on a look-up table approach to change the false color appearance of the fused image to a natural appearance. Because the resulting multiband fused image is highly dependent on the colors is a reference image, we generated a synthetic reference image. We showed that this approach could lead to more realistic color representation for images acquired in dark environments.
