Finding objects in an image scene, (feature extraction), is a very useful capability in

geospatial imagery workﬂows. Previous processes for extracting features from an image

were complex and time consuming. Now, Harris Geospatial provides a technologically

advanced approach to feature extraction that saves time and effort, while providing the

accurate results you need.

Feature extraction has a variety of practical applications, allowing you to isolate only the

objects you’re interested in, like roads, coastlines, buildings, and vehicles.

The ENVI Feature Extraction Module (ENVI FX) allows you to quickly and easily extract

features from high-resolution imagery. ENVI FX walks you through the extraction

process from image ingest to the export of results, and allows you to extract the

features you need. Rapid rendering preview screens readily allow for adjustments at any

point in the workﬂow. And, ENVI FX is built with a high performance image processing

engine to deliver fast results, even with large datasets.

An intuitive dialog box at

the beginning of the ENVI

FX workﬂow prompts you to

import a base image, ancillary

data, and a mask ﬁle.
