ImageLock Data Fusion

["Mike Pastushak" <pastushak@xxxxxxxxx>]

Dear PCI Customer,

As outlined in the July issue of the PCI User News, a new package -
ImageLock Data Fusion - has been released as a new EASI/PACE module.

Included with this message is an outline of the main features and benefits
of this package.

PCI has announced a special introductory discount of 30% off the price of
ImageLock Data Fusion for orders received before September 30, 1997.

In addition, we are offering free evaluations of the software for customers
who can access the package via ftp.

If you are interested, please send me a message at pastushak@xxxxxxxxx with
your preference:

__ I would like to evaluate the software at no charge for one month and
have access to ftp. Please send me instructions on how I may obtain the
software.
__ I would like pricing information.
__ I have more questions. Please have a salesperson contact me.

We look forward to hearing from you.

Regards,

Mike Pastushak

* ImageLock Data Fusion Outline (PCI User News article)

PCI has added a new package, ImageLock Data Fusion, to the growing list of
EASI/PACE modules.

ImageLock is an ideal solution for users who work with multi-sensor image
data. The software fuses imagery at the pixel level, allowing one to
enhance detail in Landsat imagery with SPOT data, for example. Importantly,
ImageLock preserves statistical integrity allowing operations such as
classification to be performed on the fused imagery. With the increasing
number of image sources available, ImageLock provides an essential means
through which users can effectively work with multi-sensor information.
 
The first step of the fusion process is the geometric locking of the
images. The user selects three ground control points. The software then
generates a first order registration of the images and then automatically
computes an array of control points by performing image whitening and
statistical tests on correlation peaks. The points are then used to
geometrically lock the images.

Given a set of locked images, the user may then perform a number of
operations:

- Data Fusion: Correlated high spatial frequency content from a high
resolution reference image is optimally integrated into a lower resolution
image, to yield a more detailed and more easily interpreted image.
- Noise and Artifact Removal: A clean image can be used to remove noise or
artifacts which may render the image useless for visual interpretation or
analysis.  For example, a clean TM band can be used to remove noise from
another band.
- Change Detection: A difference image may be generated by radiometrically
normalizing and subtracting two locked images. Structural differences may
be detected by analyzing the radiometric and structural variability between
images.
