Privacy Conscious Video Communication based on International Image Coding Standard

传统的视频通信系统将被反对的人的详细视频图像传输到接收器。这些系统一直忽视了人们的思想，有时他或她不想被看到。本研究旨在开发一种新的视频通信系统，它可以在接收器的显示视频中隐藏一个人。在第一年，基本的方法可以1)从视频中提取人物，2)根据人物与摄像机的距离来确定人物的隐藏程度，3)在接收器处传输显示被隐藏(模糊和半透明)人物所需的最小数据。该系统的特点是可以利用JPEG2000数字图像编码国际标准的IP核进行开发。第二年，系统已在DSP板上实现，并在实时视频处理环境中进行了评估。

Conventional video communication systems transfer video image of an objected person in details to a receiver. These systems have been neglecting person's mind that sometimes he or she does not want to be seen. This research intends to develop a new video communication system which can conceal a person in a displayed video at a receiver. In the first year, a basic method which can 1) extract a person in a video, 2) determine degree of concealment of the person according to the distance between the person and the camera, 3) transfer the minimum data necessary to display the concealed (blurred and semitransparent) person at the receiver. The proposed system has a feature that the system can be developed utilizing IP core of the JPEG 2000 international standard of digital image coding. In the second year, 4) the system have been implemented on a DSP board and 5) evaluated in real time video processing environment.
