Error correcting method for image data i.e. movement vector, on non-secured network, involves mapping available zone to image zone according to residue associated to missing zone of image data, and correcting missing zone of image data

摘要

The method involves decoding image data and data of a residue issued from a movement estimation. A missing zone of the image data is determined, and the missing zone of the image data is selected. An available zone closer to the missing zone is determined. The available zone is mapped to an image zone according to a residue associated to the missing zone of the image data. The missing zone of the image data is corrected by implementing image information of a zone whose image zone is closer. Independent claims are also included for the following: (1) a device for correcting an error in image data (2) a computer program comprising instructions for implementing a method for correcting an error in image data (3) an information medium permitting an implementation of a method for correcting an error in image data.
