Tutorials - Overview

The following tutorials give you an introduction on how to apply eCognition's new features to specific question formulations. All material is designed for self-study.

Audience

The contents are intended for beginners or for users familiar with eCognition who would like to learn more about building complex rule sets.

Requirements

To perform these guided tours or tutorials, you will need:

Tutorials

Tutorials and data are available in the Library of the eCognition Knowlege-Base - they give you a basic introduction analyzing a very simple schematic image. The key concepts are the segmentation and distinction of image objects showing how to build a first rule set.

A nice start to learn eCognition is our webinar for beginners that you can find here (1h 15 min): eCognition-for-Beginners

 

Or take a look at these short videos (3-10 min) where you learn basic steps in eCognition:

Getting Started 1 of 4: Create a project

Getting Started 2 of 4: First dynamic classification

Getting Started 3 of 4: Improve your objects

Getting Started 4 of 4: Export your results
