Abstract

This thesis aims to assess the effect of various compression options and image processing techniques for different types of fingerprint images. Also, various fingerprint matching techniques will be tested to measure the similarity between the processed and the original fingerprint image. The work evaluated the performance of JPEG, PNG, and the WSQ compression, as well as the minutiae-based, cross-correlation, and the PSNR matchers. The fingerprint image processing techniques included image normalization, binarization, depth change, noise removal, and resizing. As a result, the PNG compression recorded the best average scores for all fingerprint types according to all tested matchers. Furthermore, the JPEG compression registered the best average compression times, while the WSQ compression produced the smallest compressed file sizes. Moreover, the fingerprint image processing techniques did not improve the matching scores, but only made them worse.
