4. • Multi-perspective analysis
 Creates top down perspective map based on a camera view perspective map
 Combines different perspectives in the feature extraction process to use the best view of the data for both
horizontal and vertical analysis
 Fuse image information (i.e. color) with point cloud information (i.e. elevation) into a streamlined multi-
perspective analysis

5. • Time frame specific points
● Extended point cloud filter parameters to analyze corresponding time frame objects and points
 Focus processing on area of interest
 Enables different analysis approaches depending on distance to sensor
Land Mobile Feature Extraction

6. • 3D information in 2D image analysis
 Extended point cloud features and algorithms provide 3D structure information of 2D time frame
objects
 2D image pixel includes 3D characteristics for segmentation processes
 Enable width-, depth-, height-, position- and distance- calculation for 2D time frame image objects in
camera view projects

7. • Temporary vector concept
● Create and export 3D point vector layers
 Enables 3D point export of land mobile extraction results (3D Shapefile)
 Performance improvement by using 3D vector points instead of classified point clouds
Land Mobile Feature Extraction

8. • Temporary point cloud concept
● Create temporary (filtered) point clouds
 Enable efficient data access to focus the analysis on points
of interest
 Extract a copy for processing without modifying original
data
 Increase analysis performance
 Easy workflow (no need to export & import results)
● Transfer point information between point clouds
 Replace need to work with external algorithms
 Easy workflow (no need to export & import results)
Extended Point Cloud Handling

9. • Standardized filter concept
● Improved usability with simplified point cloud
algorithms and features
 Same filter options and parameter for all point cloud
algorithm and features
• Trimble Imaging LAS Library
● Same LAS Library in Trident, inpho and
eCognition
 Better input/output & viewing performance
 Unified point cloud handling in all Trimble Imaging
software products
Extended Point Cloud Handling

10. • Random Trees
 Fully integrated Random Trees classifier (following Leo Breiman’s theory
of random forests:
http://www.stat.berkeley.edu/users/breiman/RandomForests/)
 Remove need to work with external algorithms to save time and create a simple
workflow
• Rule Set Type Conversion
 Converting rule set item types to text and vice versa
 Using rule set items independent of the type, i.e. Scene ID  Level name
 Flexible information exchange in Rule Sets or Architect solutions
Improved Rule Set Flexibility

11. • Extended Temporary Image Layer Concept
● Stitching of temporary image and point cloud layers (Workspace Automation)
 Faster image or point cloud layer processing
● Transferring image layers between maps
 Support layer operations on different spatial resolutions or independent image object hierarchy
 Remove need to export/import results to save time and provide a simple workflow
● Trigonometric and exponential layer operations
 Support terrain and radiometric calculations (illumination, slope, aspect, etc.)

12. • Display Settings and Window Docking Management
● Configure view options in Rule Sets
 Apply different view settings during rule set runtime to focus on specific information content
 Flexible Architect solutions
● Docking Indicators, Auto hide & Group window functions
 Customized GUI control support

14. Q: How will I get eCognition 8.9?
A: All users with a maintenance contract valid on July 2013 are entitled to eCognition 8.9
at no charge. The eCognition licensing team automatically sends out download
information for all eligible customers via email. New customers should contact
eCognition sales at www.eCognition.com
Q: How can I download eCognition 8.9 for 32-bit operating systems?
A: eCognition 8.9 do not support 32-bit operating systems. Only the eCognition License
Server is available for 32-bit operation systems.
Q: Will eCognition 8.8 still run if I install eCognition 8.9?
A: eCognition 8.8 will also run on the eCognition 8.9 license therefore you can switch
between versions at any time.
Q: Will eCognition 8 rule sets run on eCognition 8.9?
A: eCognition 8.9 is downward compatible, this means you can run all 8.x rule sets.
eCognition 8.9 rule sets will not work on Developer 8.8 however.
Q: Is there a trial version for eCognition 8.9
