compute the paramters, t_down and t_up, and then apply double plateaus histogram equalization.
1 2 | EqualizeADP(im, n = 5, N = 1000, range = c(0, 255),
returnparam = FALSE)
|
im |
a grayscale image of class cimg |
n |
window size to determine local maximum |
N |
the number of subintervals of histogram |
range |
range of the pixel values of image. this function assumes that the range of pixel values of of an input image is [0,255] by default. you may prefer [0,1]. |
returnparam |
if returnparam is TRUE, returns the computed parameters: t_down and t_up. |
a grayscale image of class cimg or a numericvector
