Development of a Privacy Conscious Video Communication System Using JPEG2000 Technology

This paper aims at extracting human region based on the multi-resolution expression of Wavelet transform technique, and also creating transparent image of person based on bit-plane encoding technique, which both techniques are a constituent technology of JPEG2000. The purpose of using these techniques is to reduce the computational cost and data transfer bit rate. We developed the privacy conscious video communication system by using these techniques. In this system, the persons who stay far from the camera at the sending site are displayed as a high-transparent person at the receiving site, in order to protect their privacy.
