There are some warnings like

MITK/Modules/ToFProcessing/mitkToFCompositeFilter.cpp:244: warning: cast from 'char *' to 'float *' increases required alignment from 1 to 4 [-Wcast-align]

This is probably not dangerous, but it should be fixed at some point, either by copying data (see attached patch from my first try) or by using another OpenCV structure
