Image Gamma Correction Calculation at Kaitlyn Cowen blog

Image Gamma Correction Calculation. Gamma encoding is used to increase the quality of shadow values when an image is stored as integer intensity values, so to do gamma encoding you. For calculating gamma correction the input value is raised to the power of the inverse of gamma. \[ \text{corrected value} = (\text{input value})^{\gamma} \] where: When you map intensity values from one range to another, you can optionally perform a nonlinear mapping using gamma. The formula for this is as follows: Gamma correction works by taking a linear scale of light intensity and mapping the scale to a set of values that form a curve. There are two (easy) ways to apply gamma correction using opencv and python. The first method is to simply leverage the fact that python + opencv represents images as numpy arrays. The formula for gamma correction is: All we need to do is scale the pixel intensities to the range [0, 1.0], apply the transform, and then scale back to the range [0, 255].
