Under guidance of
Dr.K.R.Rao
Introduction
Integer DCTs compared
AVS-China [2]
H.264 [3]
VC-1 [4]
Comparison of the properties of integer DCTs
where DOT is discrete orthogonal transform and [Σ] is the covariance matrix in spatial
Choose values of θ betweent 0.1 and 1. For the same values of θ, D and RD are calculated [7].
where are arranged in decreasing order [7].
for N = 8 as a function of ρ [7].
where is the variance of the ith co-efficient in the transform domain.
