摘要

提出了一种利用嵌入小波技术对彩色图像进行编码的图像压缩算法。EW算法将子带中的小波系数重新组织成树状结构，然后有效地进行编码以进行传输。树形结构中的系数与子带中的空间位置有关。对于彩色图像，可以建立单独的树结构对每个颜色分量进行编码。这项工作的重点是研究彩色图像的联合编码方案，使用合并的树结构来保持颜色成分之间的空间关系。

Colour image compression using the embedded wavelet algorithm and merged colour tree

We present an image compression algorithm for the coding of colour images using embedded wavelet (EW) techniques. An EW algorithm reorganizes the wavelet coefficients In the subbands into a tree structure which it then efficiently encodes for transmission. The coefficients in the tree structure are related by its spatial positions in the subbands. For colour images, separate tree structures can be established for the coding of each colour component. The focus of this work is to investigate a joint coding scheme for colour images using a merged tree structure which maintains the spatial relationships amongst the colour components.
