class FrameSelectorDataSet

A dataset used to select some frames of another dataset.

Inheritance:

Public Fields

DataSet* data

DataSet where we will select frames

int* n_selected_input_frames

Number of input selected frames, for each example

int* n_selected_target_frames

Number of target selected frames, for each example

int** input_frames_indices

Indices of input selected frames, for each example

int** target_frames_indices

Indices of target selected frames, for each example

Public Methods

FrameSelectorDataSet(DataSet* data_)

void selectInputFrames(int t_, int* frames_indices_, int n_frames_)

Select input frames of the example t.

Same as selectInputFrames(), but for targets

Unselect inputs frames of the example t.

void unselectTargetFrames(int t_)

Unselect targets frames of the example t.

Documentation

A dataset used to select some frames of another dataset. It takes a dataset in the constructor. Then you call select functions to select frames. After that, when you will do a setExample() the example of the previous dataset will be returned in inputs and targets fields, with the right frames...

DataSet* data

DataSet where we will select frames

int* n_selected_input_frames

Number of input selected frames, for each example

int* n_selected_target_frames

Number of target selected frames, for each example

int** input_frames_indices

Indices of input selected frames, for each example

int** target_frames_indices

Indices of target selected frames, for each example

FrameSelectorDataSet(DataSet* data_)

void selectInputFrames(int t_, int* frames_indices_, int n_frames_)

Select input frames of the example t. Frames indices are given by frames_indices_. The size of frames_indices_ is given by n_frames_. Takes in account pushed subsets.

void selectTargetFrames(int t_, int* frames_indices_, int n_frames_)

Same as selectInputFrames(), but for targets

void unselectInputFrames(int t_)

Unselect inputs frames of the example t. Takes in account pushed subsets.

void unselectTargetFrames(int t_)

Unselect targets frames of the example t. Takes in account pushed subsets.

This class has no child classes.
