| 摘 要： | 采用专用图像压缩芯片ADV212设计了一个能对分辨力高、数据量大的图像进行实时压缩的系统.该系统能够根据输入数据率自适应调整压缩比,实时产生JPEG2000格式的码流.ADV212输出的码流经过加密后可以实时输出也可在本系统内存储.实验结果表明,该系统能满足实时性要求,同时所得重建图像具有较好的主观视觉感受和较高的峰值信噪比.

| Abstract: | By using the single-chip JPEG2000 codec (ADV212), a real-time compression system is presented for high resolution image,which contains large amount of data. This system can adjust the compression rate adaptively in accordance with input data rate. The real-time JPEG2000 code stream is generated and encrypted. And then, the encrypted code stream can either be trans- mitted directly or stored in the system. Experimental results show that the proposed coding system satisfies real-time requirement, and the reco... |
