+== Serialize ==
+Finally, as an optional step, you can serialize the obtained motion objects list using the provided serializer. The following code will return a JSON string with the moving objects:
+<syntaxhighlight lang=c++>
+rr::JsonSerializer<float> serializer;
+std::string json_str = serializer.serialize(motion_list);
+</syntaxhighlight>
+The generated JSON string will look like this:
+<syntaxhighlight lang=json>
+{
+    "ROIs": [{
+   	 "motion": [{
+   		 "x1": 0,
+   		 "x2": 0.048437498509883881,
+   		 "y1": 0.25208333134651184,
+   		 "y2": 0.34375
+   	 }, {
+   		 "x1": 0.92343747615814209,
