Abstract
Main objective of image enhancement is to process an image in order that result is more appropriate than original image for specific domain. To increasing the visual quality of image, image enhancement technique provides the large number of choices or methods. Application selection of such techniques is greatly influenced by the imaging modality, task at hand and viewing condition. This paper can give a summary of underlying ideas, together with algorithms commonly used for image enhancement. The paper focus on spatial domain method for image enhancement with explicit respect to point processing method and histogram processing method.
