A novel texture-based Automatic Fingerprint Authentication System (AFAS) is proposed. A fingerprint image is preprocessed to enhance the image by Short Time Fourier Transform (STFT) analysis. Then, three sets of invariant moment features, as a kind of texture features, are extracted from three different sizes of Region of Interest (ROI) areas based on the reference point from the enhanced fingerprint image. Each set of invariant moments contain seven invariant moments. Fingerprint verification is realized by Euclidean distance between the two corresponding features of the test fingerprint image and template fingerprint image in the database. -A novel texture-based Automatic Fingerprint Authentication System (AFAS) is proposed.

为了将零件固定在PCB上面，我们将它们的接脚直接焊在布线上。在最基本的PCB（单面板）上，零件都集中在其中一面，导线则都集中在另一面。这么一来我们就需要在板子上打洞，这样接脚才能穿过板子到另一面，所以零件的接脚是焊在另一面上的。因为如此，PCB的正反面分别被称为零件面（Component Side）与焊接面（Solder Side）。-parts to be fixed above the PCB, we will take their feet welded directly on the wiring. At its most basic PCB (single-panel), parts of which are concentrated in the side, wire were concentrated on the other side. Suppose we need burrows on the board, then through the legs of another plank, then parts of the legs is another welding in the face. Because of this, the PCB is negative components were known as surface (Component Side) and the welding surface (Solder Side).
