-
- Generalized Centroid Calculations:
- For each class, we wish to choose the best representative LP vector. The autocorrelation sequences of all blocks in the same class are averaged to find an average autocorrelation sequence. Solve the Wiener Hopf equations, the LP coefficients are obtained. They represent the generalized centroid of the LP vectors.
-
- Using the VQ, we are able to classify the image blocks to a predefined number of classes. .
