Quickly and easily extract features from imagery with this object-based tool.

Today you need to find and identify features of interest within geospatial imagery. But, the process of manually locating and digitizing these features can be complex and time consuming, and spectral content is often limited, reducing the accuracy of standard classification methods.

The new ENVI Feature Extraction Module allows you to quickly, easily and accurately extract features from high resolution imagery. This add-on module to ENVI uses object-based image analysis technology so you can extract features from readily available pan and multi-spectral imagery and data.

Programmatic Batch Capability
Extract features from multiple images automatically.

Vector Smoothing
Extracted features will now be smoothed by default.

Statistics and Results Summary
Get a summary of statistics and results from an extraction.

Save and Restore of Training Data
Save the training data from a workflow as a shapefile.

Vector Export Capability
Vector results can be exported to a shapefile.

Fast & Repeatable
Save time over traditional feature extraction methods:

Segment an image and quickly view the results in a Preview Window to assess the accuracy of the segmentation, rather than waiting for the full image to process.

Quickly adjust the segmentation scale and preview your product as many times as needed prior to full image processing.

Convenient
The ENVI Feature Extraction Module:

Allows you to extract features from pan and multi-spectral imagery - the most widely available imagery today.

Because it is an add-on module to the ENVI product, users can perform all feature extraction, image processing, analysis and visualization tasks in a single product.

Accurate
Get the accurate results you need:

Unlike traditional pixel-based approaches to feature extraction, which use the spectra of each pixel to accurately classify imagery, the ENVI Feature Extraction Module uses an object-based approach to identify and define features, providing you with accurate results even with limited bands.

The method makes it an accurate tool for use with all kinds of imagery and data types, including pan and multi-spectral imagery.

Useful
The ENVI Feature Extraction Module replaces manual digitization processes and is ideal for:

• Finding particular features across large images
• Adding new vector layers to your geodatabases
• Classifying images as outputs to be used in reports or analyses

Easy-To-Use
The ENVI Feature Extraction Module makes it easy to find what you need in your imagery:

Intuitive workflows and preview screens for ingesting images, performing segmentations, and initiating processing.

The new Preview Window allows you to quickly see processing results and readily allows for adjustments and changes.

In most cases you will only need to interact with a single parameter and the tool will automatically take care of the rest.
