8.5   Impose a Mask

Let us assume we want to cut off 20% of the border on top, 20% on the left, 10% on the right, and 10% on the bottom, then enter (20, 20, 70, 70, 2) to the second row textboxes in Figure 8.2. Click the �Preprocessing Image� button and we will have Figure 8.4.

In Figure 8.4, you will see the second image is the first image with a mask (20%, 20%, 70%, 70%). Here 2 in (20, 20, 70, 70, 2) means in percentage rather than pixels. You will see that the second image is the first image with the following cut: cut off 20 % of the border on top, 20% on the left, 10% on the right, and 10% on the bottom.

Figure 8.4  Mask (20, 20, 70, 70, 2).

Now, if we use pixels rather than percentage, enter (20, 20, 70, 70, 1) to the second row textboxes in Figure 8.2 and we will have Figure 8.5.

Figure 8.5  Mask (20, 20, 70, 70, 1).
