Image Processing Khorosware: Logarithm and Exponential Data

# Logarithm and Exponential Data

The generation of 1D data has many applications. Examples are histogram distributions and LUTs (color lookup tables). Below are two LUTs often used in image contrast enhancement, these are the logarithmic and exponential tables. The size of each one is 256 and the values range between 0 and 255.
