Functions
|
Adaptive threshold transforms a grayscale image to a binary image. |
|
Contrast Limited Adaptive Histogram Equalization (CLAHE). |
|
Increases global contrast of the image. |
|
Adaptive histogram equalization (AHE) emphasizes every local graylevel variations [1]. |
|
Gamma correction or power law transform. |
|
Trims pixel intensities which are outside the interval (minima, maxima). |
|
|
|
Rescale image intensities, between the specified minima and maxima, by using a multiplicative factor. |
|
Rescale image intensities, using a tanh fit. |
|
Sharpen image edges. |
|
Subtracts the median calculated within a sliding window from the centre of the window. |
|
Subtracts the minimum calculated within a sliding window from the centre of the window. |
|
Flexible version of median filter. |
|
Subtracts the median calculated in time and space, for each pixel. |
|
Subtracts the minima calculated in time and space, for each pixel. |
|
Flexible version of median filter. |
