First Claim
Patent Images
1. A method for automatic classification and detection of a payment gesture, comprising:
- obtaining a video stream from a camera capturing video from at least one region of interest, the region of interest associated with the type of payment gesture;
detecting motion within the at least one region of interest;
creating a representation of the motion occurring within the at least one region of interest; and
detecting the payment gesture based on the representation.

Abstract
A system and method for automatic classification and detection of a payment gesture are disclosed. The method includes obtaining a video stream from a camera placed above at least one region of interest, the region of interest classifying the payment gesture. A background image is generated from the obtained video stream. Motion is estimated in at least two consecutive frames from the video stream. A representation is created from the background image and the estimated motion occurring within the at least one region of interest. The payment gesture is detected based on the representation.

20. A computer program product comprising non-transitory tangible media encoding instructions, which when executed by a computer, perform a method comprising:
-
generating a background image from a video stream, the video stream capturing data from at least one region of interest classifying a payment gesture; estimating the motion contained in N consecutive frames taken from the video stream; creating a representation from the motion occurring within the at least one region of interest; and detecting the payment gesture based on the representation. - View Dependent Claims (21, 22, 23, 24, 25)

26. A system for automatically classifying and detecting a payment gesture, comprising:
-
a video capture unit which streams video from above a region of interest, the region of interest classifying a payment gesture; a video processing module for generating a background image and estimating the motion contained in N consecutive frames from the video steam, wherein the processing module produces a representation based on the dynamic background image and the motion within the region of interest; a detection module for analyzing the representation and determining whether the payment gesture has occurred; and a computer processor which implements the video capture unit, the video processing module, and the detection module. - View Dependent Claims (27, 28, 29)
