| 摘要: |
| 提出了一个新的位分配算法，它可以有效地分配一个给定的位的限额给任意不同的量化器集合.这种算法产生一个最佳或接近最佳位分配，它允许位分配集合值被限制成非负整数.该算法用在小波图象编码中，实验表明,这种算法是十分有效的. |

| Abstract: |
| In this paper, the authors propose a new bit allocation algorithm, capable of efficiently allocating a given quota of bit to an arbitrary set of different quantizers. This algorithm produces an optimal or very nearly optimal allocation, while allowing the set of admissible bit allocation values to be constrained to non-negative integers. It is particularly efficiency to image coding based on wavelet for using this algorithm. |
| Key words: Quantizer, bit allocation, image coding based on wavelet. |
