1. A method of obtaining a weighted combination of dynamic vision sensor (DVS) measurements and contact image sensor (CIS) measurements for determining visual inference in an electronic device, the method comprising:
receiving, by the electronic device, a plurality of DVS events and a CIS image from an image sensor;
obtaining, by the electronic device, a DVS image from the plurality of DVS events;
determining, by the electronic device, a plurality of parameters associated with the DVS image and feature velocities of a plurality of CIS features present in the CIS image;
determining, by the electronic device, a determined DVS feature confidence based on the plurality of parameters associated with the DVS image;
determining, by the electronic device, a determined CIS feature confidence based on the feature velocities of the plurality of CIS features present in the CIS image; and
calculating, by the electronic device, a weighted visual inference based on the determined DVS feature confidence and the determined CIS feature confidence.
