Title: Adaptive Histogram Modification for Enhancement the Visual Quality of Latent Fingerprints
Keywords: Histogram modification, contrast enhancement, fingerprints processing

Abstract: In the paper is presented new method for histogram modification aimed at the enhancement of the visual quality of latent fingerprints. Specific for the method is that the most important visual information is retained because in result of the processing some of the brightness values in the original image change their places in the histogram while other brightness values, corresponding with the image background, are merged. The image obtained in result, answers the requirements of the ISO/IEC SC37 standard and provides better abilities for further image processing such as fingerprints recognition and identification. The main advantage of the new method is that unlike other methods for fingerprints enhancement, based on some kind of image filtration or contrast enhancement, the presented new method improves the visual quality of the processed image, retaining the fingerprint minutiae unchanged.
