different blockbased discrete cosine transform (DCT) algorithms for compressing color image. In this RGB component of color image are converted to YCbCr before DCT transform is applied. The DCT-based orthogonal transform method proposed by Ahmed et al. 3.2 The JPEG Discrete Cosine Transform Algorithm. The JPEG DCT encoding/decoding scheme is shown in Fig.
The Discrete Cosine Transform (DCT). The key to the JPEG baseline compression process is a mathematical transformation known as the Discrete Cosine Transform (DCT).
Have a look at Fast DCT Algorithm (PDF Version). It has both DCT and Inverse DCT using DFT (FFT). They show how to do a DCT and Inverse without the reflection trick. The standard (Less efficient then
DCT For detailed method is shown in figure 1 and 2 and discussed below as follows: 2.3.1 Embedding Algorithm Visualization of embedding message in DCT-OTP transformation is shown in Fig.
Noteworthy DCT methods include the following procedures: Wang factorization [27] , Lee DCT for power-of-two block lengths [28] , Arai DCT scheme [29] , Loeffler algorithm [30] , and Feig-Winograd
