mediaLib Library Functions   mlib_SignalDTWKVectorInit_F32(3MLIB)



NAME
     mlib_SignalDTWKVectorInit_F32 -  initialization  for  K-best
     paths of vector data

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

     mlib_status mlib_SignalDTWKVectorInit_F32(void *state,
          const mlib_f32 **dref, mlib_s32 lref, mlib_s32 ndata,
          mlib_s32 kbest, mlib_s32 dtype, mlib_s32 delta,
          mlib_s32 local, mlib_s32 slope);


DESCRIPTION
     The mlib_SignalDTWKVectorInit_F32() 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.
              MLIB_DTW_L1NORM  for  L1 norm of difference (sum of
              absolute difference). MLIB_DTW_L2NORM for  L2  norm
              of difference (Euclidean distance).


     delta    The delta in the endpoint constraints.


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

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


     state    Pointer to the internal state structure.


RETURN VALUES
     The function returns MLIB_SUCCESS if  successful.  Otherwise
     it returns MLIB_FAILURE.
