Said BOUREZG
Mohamed BOUDIAF University - M'SILA -
Passionate about advancing techniques in Image and Signal Processing with a focus on medical imaging (CT, MRI) and biomedical signals (ECG, EEG). Enthusiastic about developing robust algorithms and exploring transformations (DCT, DWT, DFT) for efficient data analysis and compression. With a strong interest in communication systems, I'm eager to integrate innovative processing techniques into real-world applications. Always open to collaboration and discussions on cutting-edge methods in computational analysis and engineering.
