1. A method of delaying a periodic baseline adjustment of a plurality of touch sensor outputs on a touch sensor panel until objects having a high spatial frequency have been substantially removed from the touch sensor panel, comprising: computing a jaggedness measure for at least a portion of the plurality of touch sensor outputs based on a plurality of computed differences between the portion of the plurality of touch sensor outputs, the plurality of computed differences including differences between each of the touch sensor outputs in the portion and at least one other touch sensor output in the portion; and delaying or performing the periodic baseline adjustment of the plurality of touch sensor outputs based at least in part on the jaggedness measure.
