The strong energy compaction property of the Discrete Cosine Transform (DCT) has inspired DCT-based steganography techniques to embed secret data in large areas of the …
It has been proven that the higher the correlation level between samples in the time-domain of a digital signal, the stronger the energy com paction property in the Discrete Cosine …
Abstract The Discrete Cosine Transform (DCT) is fundamental to high-capacity data hiding schemes due to its ability to condense signals into a few significant coefficients while leaving …
The strong energy compaction property of the Discrete Cosine Transform (DCT) has been widely proposed as a solution to the capacity-quality trade-off problem in steganography …
