Abstract

A system for recognizing human activity from a video stream includes a classifier for classifying an image frame of the video steam in one or more classes and generating a class probability vector for the image frame based on the classification. The system further includes a data filtering and binarization module for filtering and binarizing each probability value of the class probability vector based on a pre-defined probability threshold value. The system furthermore includes a compressed word composition module for determining one or more transitions of one or more classes in consecutive image frames of the video stream and generating a sequence of compressed words based on the deter-mined one or more transitions. The system furthermore includes a sequence dependent classifier for extracting one or more user actions by analyzing the sequence of compressed words to and recognizing human activity therefrom.

Description

technical field [0001] This disclosure relates generally to artificial intelligence, and more particularly to recognizing human activity from video streams and symbol processing. Background technique [0002] With the advancement of technology, human activity recognition has become extremely important. Human activity recognition helps in various applications such as monitoring the checkout process in retail stores involving self-checkout (SCO) systems. Such systems allow buyers to complete the purchasing process themselves. Another application example of human motion recognition is to assist video surveillance by detecting unfair activities by shoplifters, such as theft, thereby alerting personnel employed in the shop to prevent theft. In addition, human activity recognition is also used in intelligent driving assistance systems, assisted living systems for people in need, video games, and physical therapy, among others. In addition, human activity recognition is also act...
