| 摘要: |
| 介绍了子波变换的基本理论及特点，并用它对图象进行三层分解。矢量量化优于标量量化。它已成功地应用于图象的数据压缩。文中应用矢量量化法量化图象子波域数据，取得较满意的压缩效果。 |

| Abstract: |
| In this paper，the theory and properties of wavelet transform are introduced. Vector quantization，which has been applied successfully in the image coding，is more efficient than scale quantization. We use this technique for image coding in the wavelet transform domain and get a satisfactory simulation result. |
| Keywords: wavelet transform,vector quantization,image coding |
