A novel texture
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.

水平集图像处理程序，我们提出了一个新的变分公式
水平集图像处理程序,利用一个新的变分公式进行图像处理，效果很好-Level set image processing program,we present a new variational formulation
for geometric active contours that forces the level set function
to be close to a signed distance function, and therefore
completely eliminates the need of the costly re-initialization
procedure.
