(54) Title: BABY DETECTION FOR ELECTRONIC-GATE ENVIRONMENTS 100 --. 44 FIG. 1 (57) : A baby detection system and a mass transit surveillance system are provided. The baby detection system includes a camera (110) configured to capture an input image of a subject purported to be a baby and presented at an electronic-gate system. The baby detection system further includes a memory (122) storing a deep learning model configured to perform a baby detection task for an electronic-gate application corresponding to the electronic-gate system. The baby detection system also includes a processor (121) configured to apply the deep learning model to the input image to provide a baby detection result of either a presence or an absence of an actual baby in relation to the subject purported to be the baby. The baby detection task is configured to evaluate one or more different distractor modalities corresponding to one or more different physical spoofmg materials to prevent baby spoofmg for the baby detection task.
