I'd like to link two different images in eCognition to find the same pixels on both images. The images have same projection (geog lat/long). How can I do this?
Maybe you follow the idea of a change detection - there are rule sets provided in ecognition community.
Description of one of the Rule Sets that are provided inside of eCognition Community: A project with both points of time (same pixels on both images) loaded is the basis, respectively the main map. Then for each point of time T1 and T2 maps are created containing only the respective image layers of either T1 or T2. The vegetation is classified on both Maps independently and synchronized with the main map. The actual change detection takes place in the main map, using the features 'Existence of sub-objects'.
