摘要：
In this paper we propose the application of the vector quantizers computed over an image for its own filtering. Each pixel processing is conditioned to its neighborhood and the neighborhood's closest codevector. The codevectors play the role of conditional context in a Bayesian image processing framework. The approach is applied to high resolution MRI. The visual results show that this approach produces an image smoothing with good edge preservation, although no edge model is introduced.
