Currrent script setting denoises coastguard_sequence with simulated noise. This script can be run in background in Unix/Linux using hmatbg in DenoiseDemo folder. ./hmatbg main.m outfile hmatbg can be modified to change priority level using nice command. For data corrupted by unknown Gaussian noise parameter, sdest3 funtion in Util directory can used to estimate standard deviation of the noise which is based on median of the wavelet coefficients at the finer scale. --------------------------------------------------------------------------------------- --------------------------------------------------------------------------------------- NOTE: Files in 3DBP directory for doing bandpass are from SurfBox toolbox implemented by Yue Lu and Minh N.
