Normalize ColorThe 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. However, this function can be used in conjunction with thresholding to consistently segment a color image.
1. Technique - Select which technique to use to create the normalized image.
R = R/(R+G+B)
G = G/(R+G+B)
B = B/(R+G+B)
2. Threshold - In most images not all the pixels have color information with those pixels appearing as gray scale pixels (with intensity level 0 - 255). Using the threshold you can remove the less color saturated pixels from the scene.
