From: Histogram-based normalization technique on human brain magnetic resonance images from different acquisitions

Fig. 4

This figure shows the images from top to bottom: reference Image, input image, normalized image using histogram matching, and normalized image using histogram normalization. The quality of normalized image using histogram normalization is close to the quality of reference image, better than the normalized image using histogram matching based on a joint histogram, and gains a favorable gray level of the normalized image.
