Abstract:

 


Linde-Buzo-Gray (LBG) algorithm is used in image processing for Vector Quantization (VQ). LBG

technique is robust, performs locally best but depends on the initial codebook. In the splitting based VQ, the first

center is defined as average of all vectors. The rest of 2n centres are calculated by splitting and updated procedure.

In the proposed new technique (NLBG) the LBG is improved and insted of splitting all centres into two new

areas, the worst area that has highest mean square error splitted and updated into to new areas. Therefore, the

number of codevectors is increased one by one apart from the classical LBG. Consequently, the performance of

the codebook is increased globally. In this paper, the new technique is applied to the standard images, compared

to the FCM(Fuzzy C-Means), K-Means (K – Ortalamalar) and LBG. As a result, it is seen that the proposed new

technique performs better according to the criteria of MSE.
