What’s New in eCognition 9.0

Dr. Waldemar Krebs

tranforming data into GIS ready information

Trends in Earth Observation

Increasing data volume

Increasing data

complexity

Increasing demand for

geo information

Manual interpretation

becomes a major

bottleneck

Automation

Increasing need for detailed, up-to-date information

as a basis for planning and decision making

Data+Details+Value+Complexity

Resources

Test :

25 interpreters (different levels of

experience)

Which outline is correct?

Albrecht, F. (2010): Uncertainty in image interpretation as reference for accuracy assessment in objectbased image analysis, Centre for Geoinformatics, Salzburg University, Austria

Reasons for an automated workflow

Manual digitisation and data quality: Influencing factors

eCognition Software Suite

eCognition Developer Is the development environment for

object-based image analysis.

eCognition Architect Provides an easy to use front end for

non-technical professionals allowing them

to leverage eCognition technology.

eCognition Server Provides a processing environment for

the batch execution of image analysis

jobs.

Controlled with Rule Set

• fuses raster, vector and point cloud data stacks for processing

• uses pixels, objects and object networks for superior analysis

• leverages context rules to achieve greater result accuracy

• enables 2D, 3D and time series data analysis

Object Detection

Extends the existing eCognition classification methods with computer vision based object detection, this includes GUI to collect Samples

GUI to create and evaluate Templates

Algorithm to execute Template Matching

Provides additional value remote sensing experts by improving classification results and extending eCognition to new fields of use

Template Matching

Template Matching Algorithm algorithm to execute matching procedure

If standard deviation of the template image compared to the source

image is small enough, template matching may be used

Templates are most often used to identify printed characters, numbers,

and other small objects (i.e. Trees)
