picture encoding的用法和樣例：
例句
- A novel variable-rate correlation vector quantizer is presented for image encoding in this paper.
該文提出了一種用於圖像編碼的新穎的變比特率相關矢量量化器。 - 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.
模擬結果表明，相對於其它方法，文中所提出的矢量量化圖像編碼方法運算速度更快，在同樣圖像質量下降低了傳輸過程中所需的比特率。
