In video transcoding, arbitrary resizing is always desired for end users with different display capabilities. In this paper, a two-stage resizing structure is proposed for arbitrary resizing. It gives a general solution for the realization of arbitrary resizing in the transform domain. Two constraints are given for the selection of parameter set to benefit the anti-aliasing and picture quality. Illustrative examples show that our proposed two-stage resizing structure, with the qualified parameter sets, can provide an appropriate solution for arbitrary resizing.
