MoleSense™
The software can remove hair from images:
Figure 1: Removing hair from images.
Software approach to hair removal: When removing hair from an image, the software replaces any hair color pixel with the average color of any pixels around it which are not hair.
Procedure for removing hair:
First, you need to select the hair color in the image. Then, you ask the software to remove it.
1. On the Analyze menu, point to Size and select Rectangle. The cursor changes to a cross-hair.
2. Draw a rectangle over the mole that you want to analyze (figure 2).

3. On the Analyze menu, point to Color and click Filter. The Color Filter dialog box appears (figure 3).

4. In the Color Filter dialog box click the Hair Removal Settings button. This will adjust the settings of the dialog box for hair color selection.
Procedure for dark hair
5. Click the Darkest Colors button. The pixels that contain the darkest colors will be colored/selected.
6. Keep clicking the Next Color button until all (or most) of the hair is selected, but no non-hair (e.g. skin) pixels are selected (figure 4). If you are unable to select all the hair in the rectangle without selecting non-hair pixels, you can divide the mole area into two or three different rectangles (figure 5).
Continue with step 7 below.
Procedure for white/blonde hair
5. Click the Brightest Colors button. The pixels that contain the brightest colors will be colored/selected.
6. Keep clicking the Previous Color button until all (or most) of the hair is selected, but no non-hair (e.g. skin) pixels are selected (figure 4). If you are unable to select all the hair in the rectangle without selecting non-hair pixels, you can divide the mole area into two or three different rectangles (figure 5).

7. Click the Save as Hair Color button. The colors that you have selected will be saved as "hair colors," which the software can later replace with surrounding skin colors.
8. Click the Exit button to exit the Color Filter dialog box.
9. Draw a rectangle over the mole (steps 1-2 above).
10. On the Analyze menu, point to Hair Removal and click from Image. The software will remove any hair within the rectangle.
