equalize

public void equalize(ImagePlus imp)

equalize

public void equalize(ImageProcessor ip)

Changes the tone curves of images. It should bring up the detail in the flat regions of your image. Histogram Equalization can enhance meaningless detail and hide important but small high-contrast features. This method uses a similar algorithm, but uses the square root of the histogram values, so its effects are less extreme. Hold the alt key down to use the standard histogram equalization algorithm.
