[Blindmath] Gray intensity versus outline embossing, another example

[Richard Baldwin]

The attached full-color image (pranav04.jpg) of the young man's head and
face came from Pranav's website. (It may even be Pranav himself.)

The individual is facing to your right and looking slightly downward. The
bottom of his chin is approximately centered horizontally and is about
20-percent up from the bottom of the image.

The end of his nose is slightly to the right of his chin (due to the tilt
of his head) and is about one-third of the way up from the bottom of the
image.

The bridge of his nose is slightly to the right of center and is
approximately centered vertically. Of course, his eyes are on both sides of
the bridge of his nose with the left eye being slightly lower due to the
tilt of the head.

The file named pranav04.Gray.jpg is a five-level grayscale version of the
same image. I believe this is pretty much what you would see if you copied
the original image to a multi-level embosser.

The file named pranav-Enhanced01.jpg is a five-level enhanced version of
the original image that emphasizes the outlines of the salient features of
the image and provides gray scale for accent.

The nose, lips, eyes, eyebrows, chin, and other features of his face are
outlined rather nicely in the enhanced version.

His right lower jaw is clearly outlined.

The outline of the left side of his face is somewhat weak above the left
jawbone.

He is wearing a pullover knit cap that forms an upside down bowl-shaped
semicircle on his forehead all the way back to his right ear. Without the
cap, the right ear would be visible, but it is covered by the cap. The
texture of the knit cap is fairly distinct.

His shirt or sweater forms a bowl-shaped semicircle at the neckline.

The outline of his upturned collar is clearly visible as are other features
of his jacket.

There are some bushes behind the upper portion of his head.

If you have access to a Tiger, you should be able to simply copy these
three images to the Tiger and evaluate the results.

If you have access to a sig-compatible single-level embosser, you can use
my earlier program named JpgToSig-A-01 to convert the images to sig files
for embossing. Unless you have a high-resolution embosser such as a
Phoenix, you should probably emboss the image onto two or three panels
using a slider value of about 15. Tape the three panels together and you
will have a large tactile poster of someone (possible Pranav) to decorate
your wall.

Comments are always welcome.
