Detailed Description

Quantizer is an interface for classes that serve as data quantizers.

That is, they serve to reduce the effective amount of information in a data set by algorithmically determining a small set of appropriate representatives to which the data items can be translated to. In particular, Quantizer deals with 3D acceleration data. A quantizer should be constructed with a data set with which to develop its "codebook."

Member Function Documentation

Vector<Accel3D> getDataSet

(

)

Accessor for the data set utilized by this Quantizer.

Returns:

the data set for the Quantizer

Implemented in Kmeans.

int getType

(

)

Accessor for the Quantizer type index.

Should return the value as specified in the Quantizer interface.

Returns:

the Quantizer type index.

Implemented in Kmeans.

void setDataSet

(

Vector< Accel3D >

data

)

Sets the data set to use in this Quantizer.

Parameters:

data

the data set to assign to this Quantizer

Implemented in Kmeans.

int size

(

)

Returns the size of the Quantizer, which corresponds to the size of the image of the quantization mapping.

That is, the size is the total number of representatives determined by this Quantizer for its data set.

Returns:

the size of the Quantizer.

Implemented in Kmeans.

int translate

(

Accel3D

acc

)

Translates a 3D acceleration into its appropriate representative.

Parameters:

acc

The acceleration vector to translate (quantize)

Returns:

the quantized value (an integer) which the Accel3D is mapped to in this Quantizer

Implemented in Kmeans.

Here is the caller graph for this function:
