Web1 jul. 2011 · The method suggested by Sean de is fine to normalize the maximum intensity. However, it will not necessarily give you the same appearance for both images (due to the intensity distributions not definitely being scaled by a multiplicative factor). I suggest you try the histogram transfer method in order to get a somewhat similar appearance. WebThe Normalize Color module removes all intensity values from the image while preserving color values. This module has the effect of removing shadows or lighting changes on same color pixels. The side effect of this technique is that pixels can become aberrantly colored and may not reflect the actual color value of the image.
