This paper proposes a new approach based on 4x4 discrete orthogonal Tchebichef Moment for fast and efficient image compression. The method incorporates a simplified mathematical framework technique using matrices, as well as a block-wise reconstruction technique to eliminate possible occurrences of numerical instabilities at higher moment orders. The comparison between 4x4 Tchebichef Moment Transform and Discrete Cosine Transform has been done. The results show significant advantages for 4x4… CONTINUE READING
