A method of spatial domain video enhancement/up-scaling including transforming the video input from the temporal domain to a K×K matrix of spatial domain coefficients; multiplying each spatial domain coefficient by corresponding elements of a K×K enhancement matrix to obtain enhanced spatial domain coefficients; depositing the enhanced spatial domain coefficients in the upper left K×K corner of a zero padded 2K×2K inverse transform matrix and inversely transforming them to scale the enhanced spatial domain coefficients and convert them back to video output temporal domain elements and a method of spatial domain video enhancement/down-scaling including transforming the video input from the temporal domain to a 2K×2K matrix of spatial domain coefficients; multiplying the upper left K×K corner of the 2K×2K matrix of spatial domain coefficients by the corresponding elements of a K×K enhancement matrix to obtain enhanced spatial domain coefficients; inversely transforming the K×K enhanced spatial domain coefficients to scale them and convert them back to video output temporal domain elements.
