ABSTRACT:
Method of and arrangement for image data compression by vector quantization in accordance with a precoding in blocks, thereafter comparing by means of a neural network precoded blocks with reference words stored in the form of a code book so as to transmit selected indices to a receiver. In accordance with the method, the neural network effects a learning phase with prescribed prototypes, thereafter with the aid of test vectors originating from the image generates an adaptive code book which is transmitted to the receiver. This adaptation utilizes attractors, which may be induced metastable states, of the neural network, and which are submitted to an optimizing procedure. The arrangement can process images with a view to their storage. It is also possible to utilize two devices which operate alternately, one device for generating the adaptive code book and the other one to utilize it with the object of processing television pictures in real time.
