Gamma correction
gamma_correction(image, gamma)matrix or 3-dimensional array where the third dimension is equal to 3
a positive value
depending on the input, either a matrix or an array
This function applies gamma correction to a matrix or to a 3-dimensional array where the third dimension is equal to 3. The gamma correction controls the overall brightness of an image.
path = system.file("tmp_images", "2.jpg", package = "OpenImageR")
image = readImage(path)
filt = gamma_correction(image, gamma = 0.5)
