Edges Detection Methods Based On Filtering Followed By Application Of Differential Operators For Fingerprint
AbstractThis article presents the advantages of edge detection methods using filtering operations followed by application of differential operators fingerprint an image. When using methods based on differential operators when applying intensity variations can be detected by differentiation, but if noisy signals differentiation is dangerous due to the effect of amplifying the high frequencies. To eliminate this disadvantage must be designed optimal edge detectors (Canny) which satisfy the following criteria: accurate detection, correct location and a single response to a single edge.
