| 摘 要： | 在信道带宽有限的条件下,为了保证图像目标区域具有更高的清晰度,将感兴趣区(ROI)图像编码技术引入电视制导系统中.同时,为了有效地利用图像信道进行弹上信息的传输,提出了一种基于隐式ROI的图像信息嵌入方法,通过选择适当的码块及其位平面,利用替换的方式实现了信息的嵌入,并对因信息嵌入产生的误差进行了分析.实验结果表明,与普通编码方法相比,目标区域图像质量明显提高,且信息嵌入后对图像影响较小,更适用于电视制导系统.

| Abstract: | The region of interest(ROI) image coding technology was introduced into television guided system for a higher definition of the target region in the image under limited bandwidth conditions.Meanwhile,an information embedded method was proposed based on the implicit ROI coding for effectively transmitting the on-board information through image channel.The suitable code block and its bit planes were chosen,and the information was embedded with the bit planes replacement mode.The error caused by the informatio... |
