1. A method of performing multipoint tracking, the method comprising:

  • receiving raw data of an image;

    calculating line average values for a plurality of lines of the raw data;

    filtering the raw data according to the line average values to generate filtered data;

    performing a dilation algorithm on the filtered data to generate dilated data;

    performing an erosion algorithm on the dilated data to generate eroded data;

    performing edge detection on the eroded data for identifying touch regions of the raw data;

    performing a labeling algorithm on the touch regions;

    calculating centers of gravity for the touch regions; and

    generating a multipoint tracking result according to the centers of gravity.
