1. A processing system for an input device, comprising:

  • a sensor module comprising sensor circuitry, the sensor module coupled with a plurality of sensor electrodes, and configured to;

    acquire a plurality of sensing frames comprising a first sensing frame of a first frame type, a second sensing frame of a second frame type different than the first frame type, and a third sensing frame of the second frame type,form a first differential frame relating the first and second frame types based on a comparison of the first sensing frame with the second sensing frame, andform a first normalized frame of the first frame type based on a comparison of the first differential frame with the third sensing frame; and

    a determination module configured to compare the first normalized frame with a baseline frame.
