Abstract
A method may include obtaining a capacitive image of various sensor pixels in an input device. The capacitive image may include various capacitive measurements resulting from the first input object and the second input object in a sensing region of the input device. The method may further include obtaining various pixel response functions corresponding to the sensor pixels. The method may further include determining, from the capacitive image and using a search method and the pixel response functions, various capacitive contributions of the first input object in the capacitive image and various capacitive contributions of the second input object. The method may further include determining, using the capacitive contributions of the first input object and the capacitive contributions of the second input object, a first location of the first input object and a second location of the second input object.
