Abstract
A processing system for hybrid rejection includes a sensor module coupled to sensor electrodes, and configured to acquire sensing data using the sensor electrodes. The system further includes a determination module configured to obtain a capacitive image of a sensing region based on the sensing data, determine a input object set in the sensing region using the capacitive image, obtain a profile of the sensing region based on the sensing data, and determine a contiguous region width of a contiguous region in the profile. The contiguous region corresponds to a input object in the input object set. The determination module is further configured to filter the input object from the input object set based on the contiguous region width satisfying a size threshold to obtain a filtered input object set, and process the filtered input object set.
