The modulated lapped transform: Avoiding artifacts in compressed remote sensing imagery

A fast algorithm for the computation of 2-D forward and inverse MDCT

“…The two-dimensional (2-D) MDCT/IMDCT (or MLT/MLT -1 ), belonging to the lapped transforms, have a better performance compared to the non-lapped transforms (like the 2-D DCT/IDCT), not only because they have higher coding gains, but also they lead to a strong reduction in "blocking effects" in image coding [10]. Therefore, the 2-D MDCT/IMDCT have found their applications in image coding [11,12], spectral image analysis [13] and digital image watermarking [14].…”
