Claim One:
1. For a plenoptic imaging system comprising imaging optics, a microlens array and a sensor array, the sensors in the sensor array capturing a plurality of views of an object, a method for estimating a centroid location on the sensor array, the sensor at the centroid location capturing a center view of the object, the method comprising: accessing a normalized plenoptic image of a calibration object; for a search direction, determining a search band along the search direction, the search band spanning a range of different values for the search direction; taking a plurality of slices of the normalized plenoptic image along a slice direction that is orthogonal to the search direction, each slice having a different value of the search direction within the search band; and selecting a centroid slice from among the plurality of slices based on a frequency component of the slices corresponding to a pitch of the microlens array projected onto the normalized plenoptic image, the selected centroid slice determining a centroid value for the search direction.
