An additive and multiplicative half-quadratic linearization scheme are compared and we show that the additive form is superior as all operations can be implemented in the frequency domain using the FFT. cav_un_auth*0274401 18th IEEE International Conference on Image Processing Brusel 11.09.2011-14.09.2011 BE 2012 JD 3 http://hdl.handle.net/11104/0199835 2011 pdf 1.4MB cav_un_epca*0364317 18th IEEE International Conference on Image Processing 978-1-4577-1302-6 1177 1180 Piscataway IEEE 2011
