Once the 64x64 blocks have been created, the first second and eighth Hu moments are calculated for each frame of the sequences using a batch process. This generates the periodic description of a subject's gait:

The gait signature for a given gait sequence is then calculated by taking the mean and variance of each of the moments:

This batch processing is performed by a command line application written in java.

The application runs through directories that are hard-coded in program and outputs a comma-separated-values file (moments.csv) with the mean and variance of the moments on single line for each gait sequence.
