In this paper, efficient architectures for realizing the recursive discrete cosine transform (DCT) and the recursive inverse DCT (IDCT) are proposed. By respectively folding the inputs of the DCT and ...

We use analysis tools in the MATLAB Control System Toolbox to accomplish the design and analysis. A by-product of our analysis is a simple MATLAB/Simulink model and a script that generates describing ...

A MATLAB-based implementation of fractal image compression enhanced with the Discrete Cosine Transform (DCT), focusing on optimizing compression ratio, PSNR, and memory usage.

Therefore, this research designed the Shannon–Cosine wavelet which possesses all the excellent properties such as interpolation, smoothness, compact support and normalization, then constructing ...

DCT-Based-Digital-Watermarking-GUI-with-Attacks-Analysis This Digital Watermark Embedding and Extraction GUI is a project implemented in MATLAB. It utilizes Discrete Cosine Transform (DCT) to embed a ...
