Abstract: The proposed method consists on |3D-to-2D| transformation of the temporal frames that allows exploring the temporal redundancy of the video using 2D transforms and avoiding the computationally demanding motion compensation step. This transformation turns video spatial temporal correlation into high spatial correlation. In this paper, we explore the proposed method performances and try to better show what it actually offers to users. The paper presents also the extensions chosen to reduce the perceived artefacts and increase the perceptual as well as objective (PSNR) decoded video quality, which is actually competitive with state-of-the-art video coders, especially when operating complexity is taken into account.

Keywords: nonpredictive video coding; low complexity; temporal decomposition; correlation; DCT; discrete cosine transformation; DWT; video compression; temporal redundancy; discrete wavelet transform.
