1. A method for measuring packaging effectiveness based on video-based analysis of a plurality of persons using a control and processing system that executes computer vision algorithms on a plurality of input images transferred to the control and processing system through a means for video interface, comprising the following steps of: a) processing a behavior analysis of a person based on a path analysis of the person by executing a computer vision-based tracking algorithm on the plurality of input images to obtain information about the person's behavior with package concepts using the control and processing system, b) processing a segmentation of the person, including demographic analysis, by applying a computer vision-based demographic classification algorithm to the plurality of input images in relation to the package concepts, c) detecting an emotion change of the person, d) producing indices along various interaction stages of the person with each package concept based on the behavior analysis, the segmentation, and the emotion change detection, e) sending the indices to a module for an association of measurements and analyses, which performs a package effectiveness measurement, including a comparison of the indices among a plurality of package concepts, and f) producing comparison results of the indices in relation to the segmentation, g) organizing the measurement of the packaging effectiveness based on the segmentation and trips of the plurality of persons, wherein the segmentation comprises demographic segments, including age-range, gender and ethnicity, wherein the trips comprise a shopping pattern of said plurality of persons, and wherein the indices comprise reach to attract index, attract to engage index, and engage to motivate index.
