Abstract
A system for detecting invisible human emotion in a retail environment is provided. The system comprises a camera and an image processing unit. The camera is configured in a retail environment to capture an image sequence of a person before and during when a price of a product or service becomes visible. The image processing unit is trained to determine a set of bitplanes of a plurality of images in the captured image sequence that represent the hemoglobin concentration (HC) changes of the person, and to detect the person's invisible emotional states based on HC changes. The image processing unit is trained using a training set comprising a set of subjects for which emotional state is known.
Claims16
A system for detecting invisible human emotion in a retail environment within which a product is displayed in a product display to a person, the system comprising:
- a price display device for selectively displaying at least one price of the product, pursuant to a point of sale event;
- a camera configured to capture an image sequence of the person before and during the point of sale event;
- and
- a processing unit trained to determine a set of bitplanes of a plurality of images in the captured image sequence that represent the hemoglobin concentration (HC) changes of the person, to detect the person's invisible emotional states based on the HC changes, and to output the detected invisible emotional states, the processing unit being trained using a training set comprising HC changes of subjects with known emotional states.
A method for detecting invisible human emotion in a retail environment within which a product is displayed in a product display to a person, the method comprising:
- selectively displaying, by a price display device, at least one price of the product, pursuant to a point of sale event;
- capturing, by a camera, an image sequence of the person before and during the point of sale event;
- and
- determining, by a processing unit, a set of bitplanes of a plurality of images in the captured image sequence that represent the hemoglobin concentration (HC) changes of the person, detecting the person's invisible emotional states based on the HC changes, and outputting the detected invisible emotional states, the processing unit being trained using a training set comprising HC changes of subjects with known emotional states.
