1. A method of calibrating a display system, the method comprising:
displaying a test pattern including a plurality of blobs;
detecting one or more base blobs in the displayed test pattern;
identifying, based on the detected base blobs, patches of the test pattern, wherein each patch comprises one of the base blobs and a subset of additional blobs detected in the displayed test pattern;
determining a patch location for at least one patch within the test pattern based on the subset of the additional blobs in the patch to determine a blob location for at least one detected blob;
determining a calibration parameter for the display system based on the blob location and a detected attribute of the at least one detected blob; and
calibrating the display system using the calibration parameter.
