Introduction

The human visual system responds to only wavelengths of light in the range 400-700nm. Although not perceived by the human eye, light in the wavelengths from about 800-2500nm, which represents the near-infrared region of the electromagnetic spectrum, has some interesting properties that can be utilized to enhance the look of photographic images. A number of such application have been proposed by researchers [place holder for references]. In our work, we are concerned with evaluating some of these algorithms used for contrast enhancement, haze removal and skin smoothing.

As these application work independent of each other, methods and results are discussed separately for each of these.
