Objectives
          The main objectives are:
1 - To publicize the human visual perception system;
2 - Transmit the concepts associated with the formation process of digital images;
3 - The context of digital image processing (DIP) in the acquisition and analysis of medical images;
4 - Transmit the theoretical foundations of the DIP;
5 - To give students knowledge of the main techniques of acquisition and analysis of medical images;
6 - To give students the knowledge and ability to apply techniques for improving medical imaging;
Skills that pupils should acquire:

Evaluation Methodology
          The evaluation method consists of making a written test and design and implementation of an application for analysis and / or image processing, where both components have a weight rating of 50% of the final classification. To obtain approval for the course the student must achieve a final grade, averaged from the two components of assessment, equal to or greater than 9.5.

Teaching Method
          This course is organized around theoretical sessions and practical sessions. In the theoretical sessions are taught the syllabus provided. The practical sessions are taught in the computer room where students will be able to develop medical image processing applications, using the Matlab software. Are also provided tutorial orientation sessions, using the IPT e-learning platform as a tool for disseminating information, answering questions, posting handouts, fact sheets, exercise, etc. 
Software used in class
          MATLAB - The Language of Technical Computing
