06.04.1 Chapter 06.04 Nonlinear Models for Regression-More Examples Computer Engineering Example 1 To be able to draw road networks from aerial images, light intensities are measured at different pixel locations. The following intensities are given as a function of pixel location. Table 1 Light intensities as a function of pixel location.
