Abstract
Embodiments described herein include a method for using multiple filtered images. The method includes acquiring changes of capacitance in a sensing region at a plurality of sensor electrodes in a capacitive sensor. The method also includes generating a capacitive frame based on the changes of capacitance and calculating one or more filtered capacitive frames by modifying the capacitive frame with a spatial filter. The method also includes performing clump detection on the one or more filtered capacitive frames, where clump detection includes detecting locations in each filtered capacitive frame exceeding a first threshold near locations that exceed a second threshold in the corresponding capacitive frame.
