i2k Align, based on DualAlign's i2align image registration and recognition algorithm, is the most sophisticated software package in the world for registering and aligning two-dimensional images and for constructing multi-image montages. Using the same core i2align algorithm, i2k Align can register images from many different modalities, including photographic and thermal, near and far infrared, fundus imagery, angiography, and a variety of medical image modalities. Faster and smarter than the Dual-Bootstrap (GDB-ICP) algorithm our team developed while at Rensselaer Polytechnic Institute, i2align can register almost any set of 2d images, finding the common structures in the images and ignoring the differences. If you can see common structures, i2align will find them and register the images.
Downloading and installing either the i2k Align package presents users with several different ways to exploit the power of the technology:
- A simple-to-use UI allows users
to run the software, align and montage images, and preview the results.
For many users, particularly those who want to just "see" the aligned and montaged images,
this will be enough. Checking an image montage is one clear example,
but anyone who wants to combine modalities or observe a stabilized time
series of images will find the "preview" capabilities quite powerful.
- A command-line executable allows users more control over the software and
provides the ability to align or montage multiple image sets at once.
Use of the executable is explained in detail in
-
A library and header file are provided, with a C-level interface, for
users who would like to incorporate i2k Align into
their own applications.
The location of the header files and library for both Windows and Macs is explained in
-
In addition to the image output
from i2k Align, users can output the
transformation functions that map the images on top of each other and
output the inter-image correspondences that i2align uses to drive the
registration process. This output may be obtained through
the UI, through the command-line executable and through options set in
the library function calls.
The transformations and the output correspondenses are explained in
Two different software packages are available, with i2k Align is available on both Windows (XP and Vista) and Mac (OS X 10.4 and 10.5).
