Draw-lines algorithm in 2D for iris image

Personal computers have become in a powerful tool to produce image, to interpret information or to improve the quality of the visualization of the same ones in a quick and a economic form. The algorithms used for graphics by computer, are used to create one or more images. In this work we are going to approach on the application of an algorithm for drawing lines in 2-D on images of iris in computers, which is based on concepts of analytic geometry. The implemented method uses the basic definitions of the polar coordinate equations and its transformation to the rectangular coordimates. In essence what is shown is the operation of the algorithm and that the drawing of lines in 2-D is exact and more efficient that the one developed by Bresenham to draw lines in 2-D on images of the iris. The proposed algorithm allows to make segmentation of the human eye with high accuracy; This is of much aid for the individual analysis of the eye, reason why it is an important tool in the case of surgical operations of the eye.
