Image Enhancement Techniques in the Spatial Domain: An Overview
Pushpa Mamoria, Deepa. D. Raj · SSRN Electronic Journal · 2015
Enhancement is the process of manipulating an image so that the resultant one is more suitable than the original for a specific application. Usually, the images taken by different cameras or devices are not suitable due to dull and less contrast. Using digital image processing, one can enhance or sharpen the image. Lots of techniques are available as first derivation technique like Sobel mask, second derivative technique like Laplace mask and many more. This paper highlights the different techniques of image enhancement and their importance in the spatial domain for the gray scale image.
