Objective Quality Assessment of conversion & reconstruction of image from DCT to Integer Transform & vice-versa
Mujeev Khan, Ekram Khan, M. Salim Beg · 2009
The paper compares the objective quality of standard test image akio.yuv for DCT coefficients to integer transform coefficients conversion & vice versa for the purpose of MPEG-2 to H.264 & vice versa transcoding. The conversions are compared on the basis of PSNR (peak signal to noise ratio) between original & reconstructed image after transcoding.
