ABSTRACT:
A method for smoothing artificial discontinuities between image blocks associated with digital data comprises reconstructing a block-based pixel representation of image blocks associated with digital data. If the difference between adjacent image blocks of the block-based pixel representation is less than or equal to a quantization parameter, then the method includes modifying boundary pixel values to define at least one additional frame, and displaying the at least one additional frame and an original frame in an alternating fashion so as to visually achieve smooth block boundaries between the adjacent image blocks. The method may be performed by a suitable device and/or may be embodied in an instruction set executable by such device.
