ABSTRACT
In previous chapters we discussed image filters. The filter enhances
the quality of image so that important details can be visualized and
quantified. In this chapter, we discuss a few more image enhancement
techniques. These techniques transform the pixel values in the input
image to a new value in the output image using a mapping function.
We discuss logarithmic transformation, power law transformation, im-
age inverse, histogram equalization, and contrast stretching. For more
information on image enhancement refer to [37],[71],[74].
