SWT based Composite Method for Fingerprint Image Enhancement

New technology for recognizing fingerprints for security purposes is proving reliable but efficient recognition depends on the quality of the 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 the proposed method on FVC2002 fingerprint database and experimental results show that this composite method is more effective and robust than the other existing method. Finally the result is compared using the texture descriptors
