Markers in MeVisLab

In MeVisLab you can equip images and other data objects with markers. In this example you will see how to create, process and use markers.

Creation and Rendering

To create markers, you can use a marker editor, for example the SoView2DMarkerEditor. Connect this editor to a viewer as shown below. Now you can interactively create new markers. Connect the module XMarkerListContainer to your marker editor to store markers in a list.

Example 1: Distance between Markers

Example 1: Calculating the distance between markers

     This example is also available on YouTube.

Introduction

In this example, we will measure the distance between one position in an image to a list of markers.

Steps to do

Develop your network

Add the following modules and connect them as shown.

We changed the names of the modules SoView2DMarkerEditor and XMarkerLIstContainer, to distinguish these modules from two similar modules we will add later on. Open the panel of SoView2DMarkerEditor and select the tab Drawing. Now chose the Color red.
