摘要：
Soft centroids method is proposed for binary vector quantizer design. Instead of using binary centroids, the codevectors can take any real value between one and zero during the codebook generation process. The binarization is performed only for the final codebook. The proposed method is successfully applied for three existing codebook generation algorithms: GLA, SA and PNN. (C) 1999 Elsevier Science B.V. All rights reserved.
