Add, edit or overlay text, icons and graphics on the image with this robust and flexible tool. Manipulate the annotations independent from the underlying image. Interactively rotate and scale text and icons, or move from one location to another. Save annotations with the image or separately.
Chip or resize the entire image or a region of interest. Chips may be made in pixels or numerous dimension measurements. Chips may also be scaled with the same flexibility.
The Image Compare Tool allows change detection and comparison of two images. Image sources can be of any type, allowing comparison of two images taken on different days, or any combination of visual, SAR, IR or map imagery. Images can be locked roamed (either side by side, or top and bottom), flickered, and merged. Images can also be laid one on top of another, and a porthole cut out of the top image for viewing down into the bottom image, similar to an image swipe. Pixels from one image may be "Rubbed" into the second image using the Rub-Thru tool.
Cut out portions of the image or cut an entire image and incorporate into the source image or a different image, optionally creating outline boxes. Allows maps to be added to images and vice versa.
Execute interactive histogram adjustments, region-of-interest (ROI) processing, look-up-table (LUT) modifications and digital filtering. Create an unlimited number of arbitrary ROIs for selective image enhancement and manipulate them before applying to the source image.
In addition, VITec has incorporated the ICA (Image Chain Analysis) LUT's and Filters for proper national image display.
The Spectral Exploitation Tool (SET), developed by Photon Research Associates, Inc., works in cooperation with ELT to provide access to Multi and Hyper Spectral Data. It includes tools to perform image display/enhancement, spectral analysis and integration of user algorithms for manipulation of data.
The VITec ELT - Spectral Exploitation Tool reads data from SYERS/P3I data, LANDSAT, SPOT, GEOTIFF, as well as several user defined formats. We are currently investigating the NITFS 2.1 MSI extensions.
Spectral Angle Detector - Locates materials in multi / hyperspectral images which are spectrally similar to a selected sample. This is used, for instance, to find other examples of a target paint given one sample.
Spectral Angle Material Classification - Supervised classification to segment an image into a set of similar materials based upon samples, creating, for example, a terrain categorization (TERCAT) map.
Spectral Signature Display - Allows the user to interactively read-out and plot the spectral signature (measured data for each spectral band for each pixel) for any object or material in a spectral image.
Principal Components Transform - Transformation of spectral data so that the spectral bands are "packed" and ranked with the information content in the data - this transformation increases the ability of the analyst to easily extract intelligence from difficult to interpret data. The analyst can also display lower rank principal components that often enhance rare, difficult to locate objects such as CC&D targets.
Spectral Matched Filter (SMF) - Optimal filtering operation which helps to differentiate target materials in spectral data. Similar to spectral angle search above, but more effective in many situations.
Reed - X. Yu (RX) Spectral Anomaly Detector - Unsupervised algorithm which is used to find "spectral anomalies" in data - these anomalies are often rare, spectrally unique, materials such as target coatings.
The VITec ELT Input/Output module supports any postscript printer and numerous GPIB and SCSI scanner devices. In addition, the VITec ELT Print module incorporates NGA's printer look-up-tables for the Kodak, Canon, and HP printers. These look-up-tables match the hardcopy output to the color values on the screen, providing a "what you see is what you get" capability for hardcopy outputs.
Load by image file name (File > Open) or icons (Browse) of the actual image, from a variety of sources. Browse easily through stored icons of images to locate specific images.
The VITec ELT-Mensurate module is a Graphical User Interface which provides a point and click measurement capability for use in exploitation of various imagery types. This module allows mensuration for all sensors modeled by the GOTS Ruler software. The ELT-Mensurate module also performs mensuration on all NITFs format imagery not modeled by the Ruler software. In addition, this module supports third party mensuration engines for other sensors. Other engines can be added to VITec ELT by simply adding a run-time loadable mensuration engine which models additional sensors.
The Measured Ellipse Tool allows for the drawing of Ground Truth Circles and Ellipses. Ground Truth Circles are drawn with a defined radius and Ellipses are drawn with a defined semi-major axis, semi-minor axis and orientation angle. The measured ellipse may be drawn with Center Crosshairs and/or Center Coordinate Text.
The VITec ELT Mosaic /Rectification module allows users to stitch together an infinite number of smaller images into one large scene with Quick Fit Mosaic, Ortho-Rectify a single image or create a feathered seamless mosaic.
Note: Quick Fit Mosaic uses the vci file format for large scenes that exceed the limitations of the host operating system.
The VITec ELT NITF module provides a bridge to NITF, allowing NITF files to be loaded and saved. The module is NITF certified 2.0, 2.1 (NSIF 1.0), and fully compatible with up to level 7 data. In addition, VITec ELT NITF now comes with a new SDE reader which supports several of the currently defined SDE’s. The VITec ELT NITF module is also expandable by users and integrators, so that new/private SDE’s can be processed. VITec ELT now also supplies a SPIA tag tool that has been integrated into the NITF save process.
Cut out portions of the image or cut an entire image and incorporate into the source image or a different image, optionally creating outline boxes. Allows maps to be added to images and vice versa.
The VITec ELT Register module allows tactical users to warp or rubbersheet aerial reconnaissance images to maps (ADRG’s) or other images and to quickly determine estimates of ground locations and their coordinate points on the image. As the two images are interactively merged, a single window on the screen shows the combined features of both: the satellite or aerial reconnaissance image along with the map’s latitude and longitude or universal transverse (UTM) grid coordinates. After loading the images into the module, the user is able to quickly pick features common to both images (roads, intersections, forest boundaries, etc.) and use them as control points to warp or register one image to the other.
The ELT-Roam module expands the capabilities of VITec ELT to provide fast, smooth, flicker-free, tear-free roam and pan of extremely large images. With VITec ELT-Roam, users can ingest full frame national imagery, smoothly roam images at full resolution, conduct broad area searches at user defined rates, drop markers to target additional analysis, and create any size chips on the fly. This module allows users to perform Directed Search Areas of any direction or dimension. VITec ELT-Roam delivers the perfect low cost solution for IDEX class exploitation while dramatically reducing operation and maintenance costs.
Write imagery in a variety of the file formats (Sun Raster, TIFF (GEO-TIFF), PostScript, NITFS, GIF, JPEG, etc.) to disk, printers, databases or other output devices.
The VITec ELT - Screener module allows users to waterfall, mosaic, and chip imagery from a series of image strips. The reduced resolution image strips fed into this package (typically in NITF format) are mosaiced based on GeoCoordinate information, and are displayed using a waterfall approach. The ELT - Screener module then produces a full resolution composited image chip (in the background) when users select target scenes from the reduced mosaiced scene. This chip is automatically sent to the VITec SITA (Selected Image Target Area) application for further exploitation, annotation and product generation. The ELT - Screener module also has the ability to display spot data.
The VITec ELT TFRD module allows users to load TFRD images into VITec ELT. TFRD 1.3, 2.3 and 4.3 are supported.
The VITec ELT applications programmers toolkit allows third parties to integrate VITec ELT into the existing work environment. The toolkit also allows engineers to create their own filters and look-up-tables, for ease of integration into VITec ELT. Engineers can also pass commands to VITec ELT that mimic almost every button a user can press. This allows a background process to control VITec ELT, meaning automated image processing for the user.
