WebJul 10, 2013 · H e ( u, v) = α + β H ( u, v) We added an offset and a scaling factor for the Gaussian high-pass filter. If α < 1 and β > 1, this filter will amplify the high-frequency components more than the low-frequency components. This filter is called high-frequency emphasis filter. The resulting image, typically, is sharper and also has better contrast. http://www.ttcenter.ir/ArticleFiles/ENARTICLE/3605.pdf
