CASIA-B is a large multiview gait database, which is created in January 2005. There are 124 subjects, and the gait data was captured from 11 views. Three variations, namely view angle, clothing and carrying condition changes, are separately considered. Besides the video files, we still provide human silhouettes extracted from video files. The detailed information about Dataset B and an evaluation framework can be found in this paper .

The format of the video filename in Dataset B is 'xxx-mm-nn-ttt.avi', where

xxx: subject id, from 001 to 124.
mm: walking status, can be 'nm' (normal), 'cl' (in a coat) or 'bg' (with a bag).
nn: sequence number.
ttt: view angle, can be '000', '018', ..., '180'.
