WebApr 30, 2015 · In addition, fingerprint enhancement using STFT analysis (see section ‘Fingerprint enhancement’) requires a normalized image to obtain good results. The simple normalization algorithm [ 30 ] computes the variance and mean of the image to reduce the illumination variation. Web首先利用短时傅立叶变换（Short-time Fourier Transform，STFT）对指纹图像进行增强处理，并对增强后的指纹图像进行形态学处理得到细化图像。 随后选取细化图像中的细节特征点，并以细节特征点为中心选取感兴趣区域(Region of Interest，ROI)，计算其不变矩。
