    • Improved colorization for night vision system based on image splitting 

      Ali, Ehsan A.; Kozaitis, Samuel P. (2015-02)
      The success of a color night navigation system often depends on the accuracy of the colors in the resulting image. Often, small regions can incorrectly adopt the color of large regions simply due to size of the regions. ...
