A processing system for position-filtering includes a sensor module and a determination module. The sensor module includes sensor circuitry coupled to sensor electrodes, and is configured to transmit transmitter signals and receive resulting signals with at least a portion of the sensor electrodes. The determination module is configured to determine first positional information for an input object in a sensing region based on the resulting signals, the first positional information including a detected displacement of the input object from a preceding frame, and determine second positional information from the first positional information. The second positional information includes a revised displacement determined by applying a correction factor to the detected displacement, the correction factor being based on a number of frames of the input object being detected in the sensing region, a noise scale, and a finger scale. The determination module is further configured to report the second positional information.
