2 Trimble Geospatial in the Image Processing Chain Data Acquisition Pre-processing Manual/Pixel-based Object-/contextbased Interpretation information extraction GIS/End User Slide - 2

3 Trends in Earth Observation Increasing need for detailed, up-to-date information as a basis for planning and decision making in industry, administration and security Increasing data volume Increasing data complexity Increasing demand for geo information Manual interpretation becomes a major bottleneck Automation Data/Details/Value/Complexity Resources/Productivity Slide - 3

4 Multiresolution Image Segementation pixel fine Object generation on multiple scales to adress differently scaled classification task within one project Slide - 4 medium coarse Build up a hierarchical network of image objects, which allows the representation of the image information content at different resolutions (scales) simultaneously.

5 Context classification Input image Slide - 7

6 Context classification Initial classification based on gray values Slide - 8

7 Context classification Shadow Rectangular gray area Slide - 9

8 Context classification Bright concrete between building and road Bright concrete behind building Bright concrete linear shape Slide - 10

9 Philosophy Slide - 11 Thus change your mind... Forget click and classify or (un)supervised classification for a minute. Think about using all avaiable information: image data of different scales height information thematic data And above all: Think about the reason why we as human beeings are able to perceive an object for what it is! Use your own words to describe the objects you are looking for!

10 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 Definiens technology. ecognition Server Provides a processing environment for the batch execution of image analysis jobs.
