value trace
1.ADC map was generated from DWI data and Trace D map, pseudo DWI, FA map, Dxx, Dyy, and Dzz were generated from DTI data in workstation. White matter and grey matter anatomy were assed at visual inspection, and values were measured in various brain regions. Different parameters including FA, ADC value, Trace D, T2 intensity, and pseudo DW were compared on the basis of information content.
3.Trace-driven experiments show that the TTR value obtained by ROCA is according to object modification,and fuzzy clustering algorithm can improve ROCA remarkably.
7.The concrete procedure of this method is, first, to choose a longer record segment whose seismic wavelet is stable on a single trace (or several traces), secondly, to make several shorter time windows, multiplied by a proper window function, at different locations of the record segment (or several segments), thirdly, to take the arithmetical mean of its logarithmic spectra as the logarithmic spectrum of seismic wavelet and finally, to obtain the estimation value of seismic wavelet by applying inverse homomorphic process.
