Abstract

A fast algorithm for discrete cosine transform (DCT)-domain image resizing is presented. To reduce computations, fast Winograd DCTs are applied to a recently reported image resizing scheme that uses DCT low-pass truncated approximation. Our fast algorithm yields significant improvement in computational complexity over the fast algorithm of the reported method.
