Abstract
While many animals depend on audition, olfaction, or pressure sensing, for their lives, in the case of humans vision is of utmost importance. One of the characteristic advances ofmodern times is the digitalization and processing of images. This chapter is precisely an introduction to image processing. In its first sections, the interest is centred on image filtering, improvement, certain modifications, and the emphasizing of edges and borders. This is followed by a concise description of color processing. Then, the chapter deals with important techniques of medical diagnosis related to computational tomography, like the Hough transform and the Radon transform. Section nine introduces filter banks for bi-dimensional processing. Finally, the chapter includes some experiments on using a webcam, and about the backprojection steps related to tomography.
