Constructor & Destructor Documentation

WDKDataClass::WDKDataClass (  const char *  aS  )  [inline]

WDKDataClass takes in input a formatted string (see Introductory documentation for an explanation of the format) parses it and builds an optimized data structure to perform the weighted decompositional kernel. Here is the call graph for this function:

Member Function Documentation

void WDKDataClass::ComputeNormalizationFactor (   )  [inline, protected]

Computes and stores in member variables the Norm and the 1/sqrt(Norm) for efficiency. Here is the call graph for this function:

RealType WDKDataClass::operator * (  const WDKDataClass &  aInstance  )  const [inline]

Returns the kernel between two data objects that can be one of the dot product or the histogram intersection kernel. Here is the call graph for this function:

void WDKDataClass::Optimize (   )  [inline, protected]

Optimize merges all parts with same part type (selector) for a faster computation of the kernel Here is the call graph for this function:

RealType WDKDataClass::Product (  const WDKDataClass &  aInstance  )  const [inline, protected]

Product returns the non normalized kernel

string WDKDataClass::Serialize (   )  [inline]

Serialize returns the input data in its string format previous of any optimization for output purposes
