NOTE: The following software is provided for research purposes only.
You may not distribute this software in any form without the prior
approval of the University of California.
The compressed tar file contains a README file, the segmentation
binary, a sample image file, and a program to convert the segmented
result to an image file. You may need display tools (such as
"display" from ImageMagick) to see the the raw image data on
the screen.

It should work on all win platforms.

NOTE: Some PC binaries are also compressed using tar and
"compress"ed on a UNIX machine. |

README:
File "segment" is the binary executable for color segment
algorithm. It was compiled on SGI IRIX 5.3 operating system. The
algorithm is developed by Wei-Ying Ma and B. S. Manjunath at University
of California, Santa Barbara. For more details, please read Netra
web document.
|
To run the program, type "segment" to show a list of command
line arguments.
The <5> argument "offset" is the parameter to determine
the scale factor of segmentation. For image size 256x256, offset 6 - 8
is suggested. For image size 128x128, use value around 4. The best
value of offset depends on the image. Please try around to find the
optimal value for the images you are using.
The <6> argument "estimated number of regions" is not
very effective. Give the minimum value you prefer. The program will
segment the image into minimum number of regions under the specified
"offset" value, which is usually higher than the estimated
number of regions you specified.
|
This program takes quite amount of memory.
Please use your high-end
workstation for processing.
The output the program is a file with extension "edge". It is
the edge map of segmented image. It is in compressed format. In order
to view the result. Use program "getregion" provided. The
output will be two files. One is the region label of the original image
with extension "rmap". It is a raw gray-scale image and can
be viewed.
The other file is the edge superimposed on the original image with
extension "edg2". It is in raw rgb format. Type
"getregion" to see command line arguments.
|
There are free image viewing utilities to view raw image data.
For
example, "display" from ImageMagick. You can download an old
version of display from here ( sgi and sun ).
If you use "display" type the following command:
display -size widxhei rgb:filename
File "sample.rgb" is a small sample color image for your
testing. It is 192x128 (wid x hei) in rgb raw format.

Example to run: |
| |
> segment 1 sample.rgb 128
192 8 4 |
Output: sample.rgb.edge(edgemap) |
|
|
> getregion sample.rgb 128 192 1 |
Output: sample.rgb.rmap(regionmap) sample.rgb.edg2(image with edge) |
|
> display -size 192x128 |
rgb:sample.rgb.edg2 |
