Description: 通过反复从对象中移除边缘像素，直到它们被减少到单像素宽的骨架，二值图像从而被细化得到根中轴(Smucker et al., 1987 Tanaka et al., 1995)。建立在NHI图像上的骨架化命令是用于此过程（见于Fig. 7(ii)）和计算骨架像素的数量。-The binary image was thinned to get the medial axis of roots by repeatedly removing edge pixels from the objects until they were reduced to single-pixel- wide skeletons (Smucker et al., 1987 Tanaka et al., 1995). The ‘Skeletonize’ command built into NIH Image was used for this process (Fig. 7(ii)) and the number of skeleton pixels was counted.

Description: FINDENDSJUNCTIONS - find junctions and endings in a line/edge image
Usage: [rj, cj, re, ce] = findendsjunctions(edgeim, disp)
Arguments: edgeim - A binary image marking lines/edges in an image. It is
assumed that this is a thinned or skeleton image (or
nearly so).
disp - An optional flag 0/1 to indicate whether the edge
image should be plotted with the junctions and endings
marked. This defaults to 0.
Returns: rj, cj - Row and column coordinates of junction points in the
image.
re, ce - Row and column coordinates of end points in the
image.-FINDENDSJUNCTIONS - find junctions and endings in a line/edge image

While combining the traditional method has the advantage, for the spacing, direction offset small spacing, direction offset large fracture situation, this design window constraints window method and the improved two kinds of constraints, different repair methods. Experimental results show the method to fix a more comprehensive and complete removal of pseudo-feature points, easy to program, well thinned fingerprint image fracture repair.

Description: The popular Biometric used to
authenticate a person is Fingerprint which is unique and
permanent throughout a person’s life. A minutia matching is widely used for fingerprint recognition and can be
classified as ridge ending and ridge bifurcation. In this paper we projected Fingerprint Recognition using
Minutia Score Matching method (FRMSM). For Fingerprint
thinning, the Block Filter is used, which scans the
image at the boundary to preserves th
e quality of the image and extract
the minutiae the thinned image.
The false matching ratio is better compared to the existing algorithm-The popular Biometric used to

Description: ZOOM-FFT称为细化的快速傅立叶变换，又称为选带快速傅立叶变换。ZOOM-FFT的功能是对信号的频率进行局部细化放大，使感兴趣的频带获得较高的频率分辨率。实现FFT细化功能的算法有几种，如频移法-、相位补偿法和最大熵谱法等，目前应用最关的是频移法(ZOOM-FFT is called a thinned Fast Fourier Transform, also known as Fast Fourier Transform. The function of ZOOM-FFT is to partially refine and amplify the frequency of the signal so as to obtain the higher frequency resolution of the frequency band of interest. There are several algorithms to achieve FFT refinement, such as frequency shift -, phase compensation and maximum entropy spectral method, the current application of the most relevant is the frequency shift method)
