9. The apparatus according to claim 6 , wherein the apparatus further comprises means for comparing the measurements among the plurality of package concepts asynchronously in a store and a product location during different time periods, wherein the plurality of package concepts differ at most on one factor during the different time periods.
6. An apparatus for measuring packaging effectiveness based on video-based analysis of a plurality of persons, comprising: a) at least a means for capturing images in the vicinity of a plurality of package concepts, wherein the means for capturing images captures a plurality of input images of said plurality of persons, b) at least a means for video interface that is connected to the means for capturing images, and c) a control and processing system that executes computer vision algorithms on the plurality of input images for tracking at least a person, performing a path analysis of the person based on the tracking, processing a behavior analysis of the person based on the path analysis to obtain information about the person's behavior, including engagement behavior with the package concepts, processing a segmentation of the person, including demographic analysis in relation to the package concepts, detecting an emotion change of the person, 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, 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 the plurality of package concepts, and producing comparison results of the indices in relation to the segmentation, 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.
