9.1   Good & Bad

The principle of choosing the Image Preprocessing and Image Processing filters is to make the sample objects stand out, otherwise change the options.

Do not make too many things stand out, i.e. as long as the area of interest stands out, the rest should show as little as possible.

Figure 9.1  Bad Image Processing Example.

Figure 9.2  Good Image Processing Example.


In Figure 9.1, the first image is the selected key image. The objective is to identify the logo, 2004 Davis Cup .

Figure 9.3 Image Processing Setting.

First of all, let us use the setting:

      Edge Filter = 2

      Threshold Filter = 1

      Clean-Up Filter = 2

The second image in Figure 9.1 is a preprocessed image; and the third image in Figure 9.1 is the processed image. This is a bad example of image processing, because the sample object, 2004 Davis Cup , does not stand out.

Now, we will try a different setting:

      Edge Filter = 0

      Threshold Filter = 1

      Clean-Up Filter = 16

The third image in Figure 9.2 is the processed image. This is a good example of image processing, because the sample object, 2004 Davis Cup , does stand out.
