1. A media processing system comprising: a logic device; a non-overlap region based homography calculation module executing on the logic device to calculate homography based on feature points of one planar target appearing in a non-overlap region among images captured by a multi-camera based video capture device; and an automatic checker pattern corner localization module to automatically obtain the feature points and corresponding indices for homography calculation, identify corners and number indices in an incomplete planar target, calculate a convex polygon of current corners and obtain polygon vertices, identify upper- and lower-most corners of a column by analyzing points in the polygon vertices, identify other corners in the column with upper- and lower-most corners, and identify remaining corners in other columns by location estimation.
