Latest Patents

Waleed holds a patent for a method of performing fingerprint matching. This method incorporates a matching algorithm that combines affine moment invariants (AMIs) and translation, rotation, and scaling invariants (TRS) based on moments analysis without requiring minutiae detection. The preprocessing step normalizes the fingerprint image using the Federal Bureau of Investigation's wavelet scalar quantification (WSQ) compression standard definition. The analysis of the orientation field accurately determines the reference point, and the area within a predetermined range around this point is utilized as a region of interest (ROI) for feature extraction. A directional filter bank transform (DFB) is employed to obtain directional components of the image. Furthermore, invariant moment analysis on sub-bands of the filtered images extracts features while minimizing the effects of noise and non-linear distortions. The method uses absolute distance to match the fingerprints.
