Hi All,

I was studing the xvid code and I would like to have
more information on the algorithm paper mentioned in
the implementation of IDCT

inverse two dimensional DCT, Chen-Wang algorithm      
(cf. IEEE ASSP-32, pp. 803-816, Aug. 1984)            

32-bit integer arithmetic (8 bit coefficients)        

11 mults, 29 adds per DCT   

If any one has the description of algorthim/paper, can
you pls mail it across to me.

Awaiting your response.

With regards,
R.lakshmikanth
