Image Enhancement using Histogram Equalization and Spatial Filtering

Image Enhancement is one of the important requirements in Digital Image Processing which is vital in making an image useful for various applications which can be seen in the areas of Digital photography, Medicine, Geographic Information System, Industrial Inspection, Law Enforcement and many more Digital Image Applications. Image Enhancement is used to improve the quality of poor images. The focus of this paper is an attempt to improve the quality of digital images using Histogram Equalization and Spatial Filters in MATLAB version 7.12.0.635 (R2011a) software and the results obtained are discussed highlighting the performance of each method.
