This document summarizes several papers on fingerprint identification techniques for images with different orientations. It discusses methods like discrete wavelet transform, Gabor filters, dual tree complex wavelet transform, and backpropagation neural networks. Evaluation of these techniques show they can extract features from low quality and rotated images but may struggle with large datasets or high levels of distortion. The document concludes different applications could select techniques or their combination based on required accuracy and robustness to orientation.
