******************************************************************************* Instruction for BSS2 (Nov. 5, 2012) Yagi laboratory, Department of Intelligent Media The Institute of Scientific and Industrial Research, Osaka University http://www.am.sanken.osaka-u.ac.jp/index.html ******************************************************************************* ------------------------------------------------------------------------------- 1. Contents ------------------------------------------------------------------------------- BSS3 is composed of dissimilarity score matrices from 737 subjects, which is a full set of the inertial sensor-based gait database defined in [2]. The individual dissimilarity scores are computed from the gait signals obtained by the following inertial sensors, which are attached to the each subject. - BSS3_DissimilarityScoreMatrix_Accel.csv: Accel (accelerometer) - BSS3_DissimilarityScoreMatrix_Gyro.csv: Gyro (gyroscope) Moreover, the subject ID lists for probe and gallery were provided as follows, respectively. - BSS3_ProbeIDList.csv - BSS3_GalleryIDList.csv Detailed procedures of preprocess and feature extraction are found in [1].

Protocols ------------------------------------------------------------------------------- ------------------------- 2.1 Protocol 1 (BSS3-P1) ------------------------- Two-dimensional dissimilarity scores from Accel and Gyro are fused in this protocol. Subject ID lists for training (development) and test (evaluation) of the score-level fusion are provided as follows, respectively. - BSS3_Protocol1_TrainingIDList.csv - BSS3_Protocol1_TestIDList.csv Based on the subject ID lists, sub-matrices of dissimilarity scores for training and test can be extracted for each of Accel and Gyro.
