ViewIR is a practical, user-friendly thermal image
analysis software application for the PC platform. It
is engineered to efficiently load raw thermal images,
convert the images to engineering units of
temperature or radiance, analyze multiple areas of
interest, and write the analyzed data products to an
output file.
Using ViewIR, a user can quickly process thousands
of images with little effort. This is possible with
ViewIR’s unique group select feature, which allows
simultaneous selection of multiple images from a
file. ViewIR sorts the images using the header time
stamp, then makes them available for display and
analysis with a single click of the mouse.

Areas of Interest
In many research applications, it is important to
define and analyze discrete regions of the image -
Areas of Interest (AOIs) - very precisely. ViewIR
has unique AOI drawing, editing, and storage
functions. The editing function allows the user to
graphically add or delete nodes and to move the
nodes independently on an enlarged view of the
image. A group move function simultaneously
aligns all of the AOIs while maintaining the
relative positions. The user can also name and
store each AOI for later use.
Image Series Processing
ViewIR is designed to process thousands of images
easily and efficiently. After calibrating the
software and defining AOIs, the user can load and
analyze sequential images using the same
calibration and AOIs. To quickly analyze multiple
images in series, a group file function allows the
user to load large blocks of images at the same
time. When multiple images are selected, the
software sorts them by time stamp, then with the
click of a button, sequentially loads them for
analysis.

Calibration
Image calibration functions are integrated into the
software in accordance with the imager
manufacturer’s calibration procedure. In addition,
a multiple black body calibration procedure is
available for high-fidelity applications.
Data Export
The data export feature allows the user to export
to an MS Excel-compatible file the mean, standard
deviation, and minimum and maximum pixel
values in each AOI. Individual image data
occupies one line in the file to facilitate processing
multiple images.
