Abstract
A block () of image elements () is compressed by identifying a base vector () based on normalized feature vectors () of the block (). If a position-determining coordinate () of the base vector () is present inside a defined selection section () of feature vector space (), the block () is compressed according to a default mode and an auxiliary mode to get a default and auxiliary compressed block (), respectively. The compressed block () resulting in smallest compression error is selected. If the auxiliary mode is selected, the position-determining coordinate () is mapped to get a mapped coordinate () present outside the representable normalization portion () of vector space (). The auxiliary compressed block () comprises a representation of this mapped coordinate (). If the default mode is selected no such coordinate mapping is performed and the default compressed block () instead comprises a representation of the non-mirrored coordinate ().
