Mills
There are many mills under the source directory The algorithm is using the following Mills in the order given:
MeanStdDevMill(outputs a smoothed magnitude)
LtiFilterMill (outputs derivative of the smoothed magnitude)
ZeroCrossingMill (outputs the zero-crossings of the smoothed magnitude using the derivative of it)
AccelIntervalsMill (outputs areas between zero-crossings)
WinThresholdMill (makes absolute thresholding and relative thresholding, given a window length )
WinMax (outputs the minimun and maximum for every window)
Source
CVS checkout / export
To check out the latest code: <bash>cvs -d user@bicycle.cs.washington.edu:/projects/ubicomp/uwar/CVS checkout msp_peak_detection</bash>
CVS tags
We're trying to keep our branch of msp reasonably in-sync with Intel Research Seattle's. That means we periodically merge in updates from the sourceforge repository maintained by Intel.
- msp_peak_detection
- msp_2008_02_05
- pre-merge-1
- merge-1
- merge-2
Building
msp_peak_detection is built the same way as other msp branches. <bash>cd msp_peak_detection/src ./configure # unless you're cross-compiling make cd inference make</bash> If you are cross-compiling, you'll first need to set the environment variable CROSS_COMPILE to the path to your cross-compiler and cross-binutils.
