Abstract
This relates to correcting the actual absolute capacitance values of electrodes of non-optimized geometric shapes that are connected to electronic circuits. To correct the actual absolute capacitance values, a prediction model can first be determined by carrying out nonlinear regression on the basis of actual values of absolute capacitance values from the electrodes and from a probability density image from idealized electrodes for a plurality of object positions. The prediction model can then be applied to the actual absolute capacitance values to obtain a probabilities densities image for the actual absolute capacitance values, considered to be corrected absolute capacitance values used for the detection of the object.
