Figure 14. The ZOOM-IN function for FCP labeling During the process of setting the Facial Characteristic Points on the image, the application does some checking so as to make sure the points are entered correctly. There are also some additional guiding lines drawn on the image (Figure 15). The checking rules followed are focused on the verification, whether the two or more points are on the same vertical line or at a given distance from other mark points, as described in table 6. - 66 -
Table 6. The set of rules for the uniform FCP annotation scheme Once all the FCPs are set, the application can store the data in a text file on the disk. The output file can have the same name with that of the original BMP file but with a distinct extension (“KH”), or a name specified by the user. For saving the FCP set, the user has to choose the proper option from the menu or to click on the button in the application toolbox ( ). - 67 -
