Abstract
The present invention generally relates to a method for forming a candidate fingerprint representation of a fingerprint of a finger of a user of an electronic device comprising a capacitive fingerprint sensor for sensing a fingerprint pattern, the method comprising acquiring a sequence of candidate fingerprint images each acquired at different imaging acquisition settings. Further, a fingerprint feature set is extracted from each of the candidate fingerprint images, the fingerprint features of each fingerprint set being extracted according to a first selection criterion. A feature representation set is determined for each of the fingerprint feature sets. A candidate fingerprint representation is formed from a combination of the fingerprint feature representation sets. The invention further relates to a fingerprint sensing system and an electronic device.
