## Abstract In this article, an efficient image coding scheme that takes advantages of feature vector in wavelet domain is proposed. First, a multiβstage discrete wavelet transform is applied on the image. Then, the wavelet feature vectors are extracted from the waveletβdecomposed subimages by coll
## Abstract Wavelet transform coding (WTC) with vector quantization (VQ) has been shown to be efficient in the application of image compression. An adaptive vector quantization coding scheme with the GoldβWashing dynamic codebookβrefining mechanism in the wavelet domain, called symmetric wavelet tr
