||The objective of this module consists of providing an introduction to information processing, emphasizing the mathematical theory of information and its treatment, the data compression and/or images coding, the encoding for error correction, techniques and cryptographic encoding for the security of the information, applications to communications networks, and the design of applications. After completeness of the module, the student will be able of: 1. To formulate methods for codification to forward error correction. 2. To formulate methods for the compression of data, with particular emphasis in images. 3. To decide what is the most convenient type of compression, depending on the characteristics of the images and of the transmission channel. 4. To gain some basic knowledge on cryptography. 5. To analyze and to evaluate the implementation requirements of security algorithms.
