MATLAB Code for Image Hiding Using DCT: A Comprehensive Implementation Guide
"Image hiding via Discrete Cosine Transform (DCT) involves converting an image from the spatial domain to the frequency domain to embed secret data into the least significant coefficients. In MATLAB, this is achieved using the dct2 and idct2 functions, allowing for high-capacity storage with minimal visual distortion in the cover image while maintaining robustness against common image processing attacks like compression. Understanding the Foundations of DCT-Based Steganography Steganography is the science of hiding information within a non-secret medium, such as an image, audio file, or video. Unlike cryptography, which focuses on making a mes..."
