Image Processing Algorithms Part 6: Gamma Correction – Dreamland Fantasy Studios
This article was originally published in issue 57 of The Crypt Mag Gamma, represented by the Greek letter , can be described as the relationship between an input and the resulting output. For the scope of this article the input will be the RGB intensity values of an image. The relationship in this case between the input and output is that the output is proportional to the input raised to the power of gamma. The formula for calculating the resulting output is as follows: To illustrate, here are a few gamma curves: Various Gamma Curves (click image to enlarge) Note that with a gamma of 1 the input equals the … Continue reading Image Processing Algorithms Part 6: Gamma Correction →
