# Exponential Contrast Enhancement

[Laboratory]

When images too bright, a constrast enhancement table like the exponential function can be used to darken the image. Shown below is the original image for our experiment and the exponential color table.

a)Original Image; b)Exponential Map
a) | b)

We want to map the pixel values of the original image using the exponential color table. Performing this operation yields
