Method and arrangement for forming HCVQ vector library |
摘要 |
<p>The invention relates to encoding and decoding images. The idea of the invention is to form HCVQ codevectors, in a receiving terminal. A group of codevectors forms a codebook, and a group of codebooks forms a codebook library. Only a VQ codebook and a certain number of modification vectors are sent to the receiving terminal. The compressed HCVQ vectors are formed using the received VQ and modification vectors. <IMAGE></p> |
