7 Analysis and Enhancement

9 Use the Subtract blocks to subtract the minimum values from each element

of the Gv and Gh matrices. This process ensures that the minimum value

of these matrices is 0. Accept the default parameters.

10 Use the Maximum blocks to find the maximum value of the new Gv and

Gh matrices. Set the Mode parameters to

Value.

11 Use the Divide blocks to divide each element of the Gv and Gh matrices

by their m aximum value. This normaliz ation p rocess ensures that these

matrices range between 0 and 1. Accept the default parameters.

12 View the gradient components of the image using the Video Viewer1 and

Video Viewer2 blocks. Accept the default parameters.

13 Connect the blocks as shown in the following figure.

14 Set the configuration parameters. Open the Configuration dialog box by

selecting Configuration Parameters from the Simulation menu. Set

the parameters as follows:

• Solver pane, Stop time =

• Solver pane, Type = Fixe d-st ep
