[Special Effects] Affine Transformation02 DL : 1: The transformation parameters are specified by the user by editing the values of the rotation, scale (x and y), and shear (x and y). The translation is not icluded because it can be easily (normalized or) removed from the image by subtracting the shape cetroid. The affine matrix and the affinr transformation are computed using Matlab Image Processing Toolbox functions: maketform and imtransform. So this program is only demonstrates and facilitates the computation and the applying of these functions to a 2-D image. -The transformation parameters are specified by the user by editing the values of the rotation, scale (x and y), and shear (x and y).

This system mainly deals with fingerprint image in three aspects: image preprocessing, feature extraction and feature matching. Image preprocessing includes four steps: image grayscale, filter enhancement, binarization and thinning. After preprocessing the fingerprint image, the redundant part of the original image is removed for the convenience of subsequent recognition processing. Feature extraction is mainly to extract the endpoint and bifurcation points after thinning the fingerprint image. Feature matching is to determine the two images by comparing the feature points of the two fingerprint images Whether the image comes from the same finger.)
