WebThe LBG algorithm is a generalization of the scalar quantization design algorithm introduced by Lloyd, and hence is also often called the generalized Lloyd algorithm or GLA. Interestingly, this algorithm was known earlier in the pattern recognition community as the k-means algorithm. The Linde–Buzo–Gray algorithm (introduced by Yoseph Linde, Andrés Buzo and Robert M. Gray in 1980) is a vector quantization algorithm to derive a good codebook. It is similar to the k-means method in data clustering. can i share my itunes music with my wife
