Alpha Map DEVICE AND METHOD FOR PROVIDING USER INTERACTION SERVICE BY ANALYSING ALPHA MAP

摘要

A user terminal for providing a bidirectional service through an alpha map analysis includes: an image acquisition part for acquiring a reference image and a real-time image; an alpha map generation part for comparing the reference image and the real-time image to generate the alpha map of each frame of the real-time image; an alpha map analysis part for analyzing the alpha value of the alpha map to determine a control object and analyzing the alpha value of the control object to generate a control signal for a control target device; and a control signal transmitting part for transmitting the control signal to the control target device.
