The present invention is a system and framework for augmenting any retail transaction system with information about the involved customers. This invention provides a method to combine the transaction data records and a customer or a group of customers with the automatically extracted demographic features (e.g., gender, age, and ethnicity), shopping group information, and behavioral information using computer vision algorithms. First, the system detects faces from face view, tracks them individually, and estimates poses of each of the tracked faces to normalize. These facial images are processed by the demographics classification module to determine and record the demographics feature vector. The system detects and tracks customers to analyze the dynamic behavior of the tracked customers so that their shopping group membership and checkout behavior can be recognized. Then the instances of faces and the instances of bodies can be matched and combined. Finally, the transaction data from the transaction data and the demographics, group, and checkout behavior data that belong to the same person or the same group of people are combined.

A reverse filter operates for adding noise n(x,y) to an output of a deteriorated model of a blurring function H(x,y) to output an observed model g(x,y). The blurring function inputs a true picture f(x,y) to output a deteriorated picture. The reverse filter recursively optimizes the blurring function H(x,y) so that the input picture signal will be coincident with the observed picture. In this manner, the reverse filter extracts a true picture signal. A corresponding point is estimated, based on a fluency theory, on the true input picture signal freed of noise contained in it by the reverse filter (20). The motion information of a picture is expressed in the form of a function. A plurality of signal spaces is selected by an encoder for compression (30) for the input picture signal. The picture information is expressed by a function from one selected signal space to another. The motion information of the picture expressed by the function and the signal-space-based picture information expressed in the form of a function are expressed in a preset form to encode the picture signal by compression. The picture signal encoded for compression has its frame rate enhanced by a frame rate enhancing processor (40).
