In air signature databases

Two in-air signature databases were created. Forty participants voluntarily took part in each of the two databases’ construction. Some of them participated in both databases construction. Each participant signs in the air five signatures and imitates five signatures of five other participants.The proposed protocol for data acquisition consists of two ways for the two in-air signature databases respectively. In the first database, the participant sign in the air directly in front of the camera. In the second database, the participants sign in the air using a transparent glass plate between them and the camera. The data recorded on two files:-         The first file is a CSV file that contains the 2D coordinates of the signature in the air (x(t) and y(t)).-        The second is an image file of the signature in the air.
