Abstract
Image enhancement approaches adopting histogram equalization can be broadly categorized into classes of global and local equalization implementation. The former method conducts equalization over all image pixels concurrently. In a canonical implementation, the resultant image has a histogram resembling a linear transformation or stretching from its original image histogram. In spatial relationships between neighboring pixels were taken into consideration.
Keywords:
image enhancement; histogram equalization; image quality measurement
