Abstract
Error concealment apparatus for concealing corrupted data elements in frequency separated digital image data (such as sub-band coded image data) is described. Depending on the spatial frequency represented by a corrupted data element, one of a number of error concealment means is selected to conceal the error. In this way the error concealment used can be tailored to suit the different properties of the various spatial frequency components in the frequency separated image.
