Image processing is the use of algorithms to perform
various operations on digital images. The techniques that are
explained further are image segmentation and image
enhancement. Image Segmentation is a method to partition an
image into multiple segments, to change the presentation of an
image into something more meaningful and easier to analyze. The
current image segmentation techniques include region-based
segmentation and edge detection segmentation. Image
Enhancement is the process of improving the quality of image.
Under this section there are two broad divisions- Spatial Domain
Technique and Frequency Domain Technique.
