A block of image elements is compressed by determining a parameter representative of a size of a bounding section in vector space encompassing feature vectors associated with the image elements. This size parameter is used to provide a deterministic, pseudo-random pattern of multiple representation vectors encompassed by the bounding section. A vector among multiple representation vectors is selected as representation of the feature vector of an image element. An identifier associated with selected vector is assigned to the image element and included in the compressed block which also comprises representations of the size parameter.
