- W2010759788 abstract "Discrete cosine transform (DCT) and inverse DCT (IDCT) have been widely used in many image processing systems and real-time computation of nonlinear time series. In this paper, the unified DCT/IDCT algorithm based on the subband decompositions of a signal is proposed. It is derived from the data flow of subband decompositions with factorized coefficient matrices in a recursive manner. The proposed algorithm only requires<mml:math xmlns:mml=http://www.w3.org/1998/Math/MathML><mml:mrow><mml:mo stretchy=false>(</mml:mo><mml:msup><mml:mn>4</mml:mn><mml:mrow><mml:mo stretchy=false>(</mml:mo><mml:msub><mml:mrow><mml:mi>log</mml:mi></mml:mrow><mml:mn>2</mml:mn></mml:msub><mml:mi>n</mml:mi><mml:mo stretchy=false>)</mml:mo><mml:mo>−</mml:mo><mml:mn>1</mml:mn></mml:mrow></mml:msup><mml:mo>−</mml:mo><mml:mn>1</mml:mn><mml:mo stretchy=false>)</mml:mo></mml:mrow></mml:math>and<mml:math xmlns:mml=http://www.w3.org/1998/Math/MathML><mml:mrow><mml:mo stretchy=false>(</mml:mo><mml:msup><mml:mn>4</mml:mn><mml:mrow><mml:mo stretchy=false>(</mml:mo><mml:msub><mml:mrow><mml:mi>log</mml:mi></mml:mrow><mml:mn>2</mml:mn></mml:msub><mml:mi>n</mml:mi><mml:mo stretchy=false>)</mml:mo><mml:mo>−</mml:mo><mml:mn>1</mml:mn></mml:mrow></mml:msup><mml:mo>−</mml:mo><mml:mn>1</mml:mn><mml:mo stretchy=false>)</mml:mo><mml:mo>/</mml:mo><mml:mn>3</mml:mn></mml:mrow></mml:math>multiplication time for<mml:math xmlns:mml=http://www.w3.org/1998/Math/MathML><mml:mrow><mml:mi>n</mml:mi></mml:mrow></mml:math>-point DCT and IDCT, with a single multiplier and a single processor, respectively. Moreover, the peak signal-to-noise ratio (PSNR) of the proposed algorithm outperforms the conventional DCT/IDCT. As a result, the subband-based approach to DCT/IDCT is preferable to the conventional approach in terms of computational complexity and system performance. The proposed reconfigurable architecture of linear array DCT/IDCT processor has been implemented by FPGA." @default.
