摘要：In an uncontrolled environment such as crime scene, collecting valid fingerprints is a very challenging task, due to the fact that fingerprints are often superimposed with some background. In some cases the background may be another fingerprint due to multiple touches by a person, resulting into segments of the overlapped fingerprints. In order to use existing fingerprints recognition systems for identifying such fingerprints, a method for separation of overlapped fingerprints is the current need. This separation takes few steps like segmentation of overlapped region, feature extraction and separation. This paper presents a novel method for segmentation of overlapped region based on morphological image processing. The algorithm is tested on overlapped fingerprints from simulated overlapped fingerprints database. Results indicate that the proposed algorithm is satisfactory for good quality images and it requires improvement for poor quality fingerprints in the overlapped region.
