Context Hand gesture recognition database is presented, composed by a set of near infrared images acquired by the Leap Motion sensor. Content The database is composed by 10 different hand-gestures (showed above) that were performed by 10 different subjects (5 men and 5 women). The database is structured in different folders as: - /00 (subject with identifier 00) * /01_palm (images for palm gesture of subject 00 ) + /01_palm/frame_197957_r.png,...,frame_198136_l.png, ... (images that corresponds to different samples obtained for the palm gesture performed by the subject with identifier 00) - /02_l (images for l gesture of subject 00 ) - /10_down - /01 - /02 - /09 (last subject with identifier 09) Every root folder (00, 01,...) contains the infrared images of one subject. The folder name is the identifier of each different subject. Citation T. Mantecón, C.R. del Blanco, F. Jaureguizar, N.
