Abstract
A method and apparatus for performing data compression is disclosed that does not require interpolation of pixel data in order to define image blocks. More specifically, the present invention provides spatially interleaved image blocks composed of high frequency image components by sampling the high frequency image components at a pitch or spatial sample frequency equal to that of the low frequency image components. The present invention provides the added advantage of reducing the number of image blocks that must be defined in order to perform data compression.
