18.2   Image Preprocessing

Figure 18.2  Image Preprocessing.

Border Cut

    Use the “Border Cut” parameter to cut the border areas. Enter N to the first textbox in Figure 18.2, then N% near the border will be cut off.



    Use the “Mask” parameter to impose a mask on the input images. Enter (x, y, w, h, 2) to the second row in Figure 18.2; then a mask in percent value will be imposed on the input images. Enter (x, y, w, h, 1) to the second row in Figure 18.2; then a mask in pixel value will be imposed on the input images.


Stick Shift

    Use the “Stick Shift” parameter to speed up the computation.  Set “Stick Shift” in Figure 18.2 between 0 and 5, with 0 being the slowest and 5 being the fastest.

Skip Empty Board

Skip Percent

Skip Threshold Filter

Skip Edge Filter

    Use these parameters to skip the border area by cutting off N% percent of the contents.

    The “Skip Empty Border” parameter in Figure 18.2 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 user defined Threshold Filter;

            6   Skip x percent of the contents on user defined Threshold/Edge Filters.

    Use the “Skip Percent” parameter to specify the percentage of content you want to cut off for Options 3, 4, and 6.

    Options 1, 2, and 5 use the default setting, which is 2%. Use the “Skip Threshold Filter” and “Skip Edge Filter” to set the Edge Filter and Threshold Filter, respectively.
