Abstract
Apparatuses and methods of peak detection are described. One method measures touch data on a sense array, the touch data represented as multiple cells. The method performs multiple different peak-detection schemes on each of the cells to generate a list of one or more possible peaks in the touch data. The method selects one or more actual peaks from the list. The actual peaks are used to determine locations of touches proximate to the sense array.
