Reconfigurable implementation of recursive DCT kernels for reduced quantization noise
نویسندگان
چکیده
Time multiplexed implementations of the recursive DCT processors are widely used in many multimedia and compression applications. Recently proposed three Goertzel kernels offer significant improvement (up to 90 %) in the noise performance of the time-multiplexed architecture to allow word-length specifications get reduced. In this paper, a highly optimized reconfigurable DCT architecture is proposed that can perform the function of three different kemels (Type A, B and C) on Virtex FPGA.

Abstract: A coordinate rotation digital computer (CORDIC) based variable length reconfigurable DCT/IDCT algorithm and corresponding architecture are proposed. The proposed algorithm is easily to extend to the 2-point DCT/IDCT. Furthermore, we can easily construct the N-point DCT/IDCT with two N/2-pt DCTs/IDCTs based the proposed algorithm. The architecture based on the proposed algorithm can su...
متن کاملDetection of perturbed quantization (PQ) steganography based on empirical matrix
Perturbed Quantization (PQ) steganography scheme is almost undetectable with the current steganalysis methods. We present a new steganalysis method for detection of this data hiding algorithm. We show that the PQ method distorts the dependencies of DCT coefficient values; especially changes much lower than significant bit planes. For steganalysis of PQ, we propose features extraction from the e...

The Discrete Cosine Transform (DCT)-based image compression is widely used in today’s communication systems. Significant research devoted to this domain has demonstrated that the optical compression methods can offer a higher speed but suffer from bad image quality and a growing complexity. To meet the challenges of higher image quality and high speed processing, in this chapter, we present a j...
