picture encoding的用法和样例：
例句
- A novel variable-rate correlation vector quantizer is presented for image encoding in this paper.
该文提出了一种用于图像编码的新颖的变比特率相关矢量量化器。 - Simulated results indicate that, compared with other decoding methods, the proposed method speeds up the encoding and reduces the bit-rate with the image quality keeping unchanged.
仿真结果表明，相对于其它方法，文中所提出的矢量量化图像编码方法运算速度更快，在同样图像质量下降低了传输过程中所需的比特率。
