	There has been made SVGA BGI drivers for the Borland compilers.
You can find them at most MS-dos ftp sites. Look for a file called SVGABGI.ZIP
or something similar. (There is also a BGI driver for printers called something
like prntbgi.zip). Even though you won't be able to use  256 grascale I have
found out that it is very difficult to see more that 64 greaylevels anyway.

That is not a good solution (GIF's). They are difficult to zoom into,
and separate files need a lot of space. Why not use the NASA vectored
worldmap (available forexample in file Worlddatabase.lzh on many Amiga

I knew about 2 seconds after I posted that article about G and W that
I should have mentioned the error so here goes...

In the section about the discrete cosine transform they define
the 1D DCT as ...cos((2x+1)u*pi/N)...  When they combine two 1D
DCT's to form the 2D transform they pull out the 1/N as the argument
to the cos to form ... (1/N^2)cos((2x+1)u*pi)*cos((2y+1)v*pi) which
is essentially saying that cos(x/n)*cos(y/n) = (1/n^2)cos(x)cos(y).

It is corrected in the Gonzalez and Woods version.

Hello,

I am writting some code to patch into a program at work.
Right now we are able to define an area of interest of a 
box/rectangle and line.  With this info we produce histograms
of the defined AOI.  We would like to add an AOI of a circle.
Now drawing the circle is no problem, but how do I go about
figuring out all the coordinates of the interior of the circle?
The coordinates are necessary since we use extended memory
to hold the image.  Once I get the coords the pixels are no
problems. 

So has anyone written C code or an algorithm to do this.

TIA,
paul

Regarding that posting which you may have happened to notice, we

The Wang Integrated Imaging System (recently ranked as the number one
document imaging system by Computerworld) has been ported to AIX, with
equivalent or better functionality, and named OPEN/image for AIX.
Customer shipments began in September.

While "many vendors have been mimicking WIIS...., Wang has stayed ahead
by adding color and gray-scale support.  Wang is the only major
document imaging vendor to have achieved this," said Rich Barrett, manager
of the client/server component of the product.   The development group
also significantly improved the speed of black and white images.

Full information and demonstrations are now available from any
Wang office or Wang imaging business partner worldwide.

Subject: 3d Medial Axis (was 3D Interrogation Software)
Date: 28 Sep 92 19:28:19 GMT
Followup-To: sci.image.processing


Well, I've only gotten a couple of nibbles for 3D interrogation
software, but I have had a bunch of folk ask me about my 3D medial
axis algorithm.  So, here it is.  I can't believe this isn't out
there somewhere in the literature -- or else it doesn't work
nearly as well as I think it does.  Now I'm paranoid.
Anyway, take a look. No guarantees.  

My method is pretty brute force, and works only for binary images,
is slow, but seems to work OK, given lots of time and effort.  It is an
extension of something John Gauch did for 2D images when he was
a grad student at UNC.
  
It consists of:

1) Find the 3D radius functions for all voxels (this is done simply
by an erosive method).

2) Sort the non-zero voxels by radius.

3) For each non-zero voxel, starting with those with the larger radii{
	For each voxel with a smaller radius (e.g. the rest of the list){
		if the voxel with the larger radius "covers" the voxel
			with the smaller radius, discard the smaller one.
		}
	}

4) What's left is on the axis.


Covering is simple to calculate, e.g. let X be the center of the
"big" voxel with radius R and x be the center of the "little" voxel with
radius r, then the big one covers the little one if the distance
|X-x|+r is less than or equal to R.

This leaves some bad spots due to discretization, where there is a loss 
of connectivity at some places where the radius decreases.  One example is
a configuration like :

*****
**********
*****

which has a radius function of:

11111
2222111111
11111

(the rest of the object is off to the left) and which gives a skeleton of:

**** *****

instead of:  

**********

.

Thus, I have a few heuristics to go back and look to fill in missing
spots.  One of the reasons that I am looking for a 3D interrogation 
tool is so I can see exactly how well this is working on complicated 
data sets.

Depending on the video card you have, you can select a 1024x768 16 color mode
which would allow you to see more of your image. We switched from Desqview/X
to DEC eXcursion for MS-Windows as it allows scrolling around an X-window,
and simulates 256 colors on 16 color displays. It supports FTP TCP/IP and

midsaggital dimensions of vocal tracts from the glottis to the lips during
vowel production. 
(2) Corresponding first three formant frequencies and,
hopefully, the fundamental frequency. 
(3) Such data measured from either
adult male or female subjects.  The data will be used to derive a midsaggital-
to-area conversion method and to estimate formant conversion factors between
male and female subjects. 

Any suggestions on finding this kind of data would be appreciated.

	In addition to the NASA data that has already been described, there
is the Defense Mapping Agency (part of US/DOD) World Vector Shoreline Data.
The WVSD is much higher resolution than the NASA data and I believe is now
available for commercial use.  Forgive me but I don't remember the resolution
offhand and I couldn't find it quickly.

	I use their Digital Terrain Elevation Data (DTED) and find it to be
a nice product.  Mail me if you are interested.
