IMAGE ENHANCEMENT USING CONTRAST STRETCHING ON RGB AND IHS DIGITAL IMAGE
Abstract: Low contrast image
has relatively bad quality since its information can not be directly
interpreted by human eyes. It’s quality can be improved using contrast
stretching operation. The objective of this paper is to design software for
enhancement using contrast stretching on RGB and IHS digital image models. The
operation is a point operation, that each pixel on the image is processed
individually, by darkening dark pixels and brightening bright pixels. The
development of the software was done using TBitmap class in Borland Delphi 6.0.
Tests have been performed on BMP and PEG grayscale as well as color images. The
test result shows that the developed software is capable to enhance the
contrast of the sample images, which are shown by the expansion of the
histograms of the images.
