mediaLib Library Functions   mlibSignalDTWKVectorInitS16(3MLIB)



NAME
     mlibSignalDTWKVectorInitS16 -  initialization  for  K-best
     paths of vector data

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlibstatus mlibSignalDTWKVectorInitS16(void *state,
          const mlibs16 **dref, mlibs32 lref, mlibs32 ndata,
          mlibs32 kbest, mlibs32 dtype, mlibs32 sref,
          mlibs32 delta, mlibs32 local, mlibs32 slope);


DESCRIPTION
     The mlibSignalDTWKVectorInitS16() function initializes the
     internal  state structure for dynamic time warping (DTW) for
     K-best paths of vector data.


     The init function performs internal state structure  alloca-
     tion  and  global initialization. Per DTW function call ini-
     tialization is done in DTW function, so  the  same  internal
     state  structure  can  be  reused  for multiple DTW function
     calls.

PARAMETERS
     The function takes the following arguments:

     dref     The reference data array.


     lref     The length of the reference data array.


     ndata    The length of each data vector.


     kbest    The number of the best paths evaluated.


     dtype    The type of distance metric between  data  vectors.
              MLIBDTWL1NORM  for  L1 norm of difference (sum of
              absolute difference). MLIBDTWL2NORM for  L2  norm
              of difference (Euclidean distance).


     sref     The scaling factor of  the  reference  data  array,
              where    actualdata    =    inputdata   *   2**(-
              scalingfactor).

     delta    The delta in the endpoint constraints.


     local    The  type  of  the  local  continuity  constraints.
              MLIBDTWITAKURA for Itakura type constraints.


     slope    The type of the slope weighting. MLIBDTWNONE  for
              no slope weighting.


     state    Pointer to the internal state structure.


RETURN VALUES
     The function returns MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
