Overview: 

Natural daylight color visualization for NIR multispectral [700-1100 nm] imagery.

Key Features: 

  • Capacity to provide near natural colour images, using multichannel NIR data, even in the complete absence of light in the visible band.
  • To distinguish objects on the basis of their different visible band responses.
  • Image segmentation of the multichannel NIR data followed by piecewise separate transformations applied to different segments  yields the desired results.
  • The individual colour transformations are initially learned one-time using manually selected inputs.

Applications: 

  • Huge potential in surveillance, reconnaissance, and security applications.
  • Defence, paramilitary and State police personnel.
