8.7 Skip the Empty Border by Content Percent
The last function for the Preprocessing filter is to skip border by content percent, not pixel percent.
The �Skip Empty Border� field in Figure 8.2 specifies the type:
0 No skip;
1 Skip the white empty border space;
2 Skip the black empty border space;
3 Skip x percent of the contents on the white background space;
4 Skip x percent of the contents on the black background space;
5 Skip empty border space on the user defined Threshold Filter;
6 Skip x percent of the contents on the user defined Threshold/Edge Filters.
We will discuss Threshold/Edge Filters in the next chapter, Image Processing.
Example 1. Set �Skip Empty Border� = 2, means skipping the black empty space on the edge. The result is shown in Figure 8.6; you will see that the second image is the first image without a black border.

Example 2. Set �Skip Empty Border� = 4, means skipping the black empty space on the edge. Set �Skip percent� = 10. The result is shown in Figure 8.7; you will see that the second image is the first image with 10% of the contents cut on each side.
