1. A processing system for hybrid rejection comprising: a sensor module coupled to a plurality of sensor electrodes, and configured to: acquire, using a first sensing technique, first sensing data, wherein the first sensing technique comprises: driving a first subset of the plurality of sensor electrodes with a plurality of transmitter signals, and receiving, based on the plurality of transmitter signals, a first plurality of resulting signals from a second subset of the plurality of sensor electrodes, and acquire second sensing data using a second sensing technique and a third subset of the plurality of sensor electrodes, wherein the second sensing technique is different from the first sensing technique; and a determination module configured to: obtain a capacitive image of a sensing region based on the first sensing data, determine a first input object set in the sensing region using the capacitive image, obtain a first capacitive profile of the sensing region based on the second sensing data, wherein the first capacitive profile corresponds to changes in capacitive coupling between the first input object set and the third subset of the plurality of sensor electrodes, determine a first contiguous region width of a first contiguous region in the first capacitive profile, the first contiguous region corresponding to a first input object in the first input object set, filter the first input object from the first input object set based on the first contiguous region width satisfying a size threshold to obtain a first filtered input object set, and process the first filtered input object set.
