In contrast, standard FD is not adaptive but instead uses specific Gabor Wavelets to pinpoint frequencies of interest with a great deal of flexibility. i.e. it produces a small part of that analytic wavelet representation within the HDFD.
Our work on standard FD and HDFD has revealed that they are in fact complimentary in many Geological Expression workflows. However, the high vertical resolution provided by the HDFD is very important for interpretative objectives at reservoir scale.
