ABSTRACT:
A method of error concealment that includes providing a first set of image data at a first time instant, providing a second set of image data at a second time instant, representing the first set of image data by a model of updating mixture of principal components (UMPC) to form a UMPC model having a plurality of components, receiving the second set of image data, wherein the second set of image data contains error-free data, and updating the UMPC model using the error-free data at the second time instant.
