    Data Set Information:

    The dataset (movement_libras) contains 15 classes of 24 instances each, where each class references to a hand movement type in LIBRAS.

    In the video pre-processing, a time normalization is carried out selecting 45 frames from each video, in according
    to an uniform distribution. In each frame, the centroid pixels of the segmented objects (the hand) are found, which
    compose the discrete version of the curve F with 45 points. All curves are normalized in the unitary space.

    In order to prepare these movements to be analysed by algorithms, we have carried out a mapping operation, that is, each
    curve F is mapped in a representation with 90 features, with representing the coordinates of movement.

    Some sub-datasets are offered in order to support comparisons of results.


    Attribute Information:

    90 numeric (double) and 1 for the class (integer)
