1. A processing system for hybrid rejection comprising: a sensor module coupled to a plurality of sensor electrodes, and configured to: acquire sensing data using the plurality of sensor electrodes; a determination module configured to: obtain a capacitive image of a sensing region based on the sensing data, determine a first input object set in the sensing region using the capacitive image, obtain a first profile of the sensing region based on the sensing data, determine a first contiguous region width of a first contiguous region in the first 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.
