Discrete Cosine Transform
نویسنده
چکیده
Discrete frequency transforms provide a method to obtain a global view of data within a window. Discrete cosine transform is the frequency transform for practical image processing because of its excellent energy compaction property. Another reason for its popularity is the existence of a fast implementation for the algorithm. In this article, the basics of the discrete cosine transform, its use for image compression, and a few variants of the transform coding for compression are considered.

On discrete cosine transform
The discrete cosine transform (DCT), introduced by Ahmed, Natarajan and Rao, has been used in many applications of digital signal processing, data compression and information hiding. There are four types of the discrete cosine transform. In simulating the discrete cosine transform, we propose a generalized discrete cosine transform with three parameters, and prove its orthogonality for some new...

The paper presents novel recursive algorithms for realization of one-dimensional type-II discrete cosine transform (DCT) and inverse discrete cosine transform (IDCT) of any length. By using some mathematical techniques, recursive expressions for DCT and IDCT have been developed. The number of additions and multiplications in the recursive algorithm for DCT are less in comparison with some other...
متن کاملA Polynomial Approach to Fast Algorithms for Discrete Fourier-cosine and Fourier-sine Transforms
The discrete Fourier-cosine transform (cos-DFT), the discrete Fourier-sine transform (sin-DFT) and the discrete cosine transform (DCT) are closely related to the discrete Fourier transform (DFT) of real-valued sequences. This paper describes a general method for constructing fast algorithms for the cos-DFT, the sin-DFT and the DCT, which is based on polynomial arithmetic with Chebyshev polynomi...

A novel method for100Gbpsall-optical OFDM using Discrete Cosine Transform in a Radio-Over-Fiber link is proposed. The system is designed simply using both symmetric and asymmetric passive optical couplers. DCT is achieved all-optically by adjusting the length and splitting ratio of the couplers. The performance of the system is compared with all-optical OFDM based on Discrete Fourier, Discrete ...
متن کاملDiscrete cosine transform
The discrete cosine transform (DCT) is a Fourier-related transform similar to the discrete Fourier transform (DFT), but using only real numbers. It is equivalent to a DFT of roughly twice the length, operating on real data with even symmetry (since the Fourier transform of a real and even function is real and even), where in some variants the input and/or output data are shifted by half a sampl...
