SWT based Composite Method for Fingerprint Image Enhancement

New technology for recognizing fingerprints for security purposes is proving as regards as reliable but efficient recognition is depending on the quality of input fingerprint image. Recognition of the fingerprint becomes a complex computer problem while dealing with noisy and low quality images. The proposed SWT based composite method is used for fingerprint image enhancement using SWT transform, morphological operation, quick mask and spatial filters. We have applied proposed method on FVC2002 fingerprint database and experimental results shows that this composite method is more effective and robust than the other existing method. Finally the result has compared using the texture descriptors.
