NIST Fingerprint Image Registration Library (NFRL). Registers a pair of fingerprint images using two pairs of control-points (pixel locations). Registration is rigid; translation and rotation are performed without scaling.
NFRL registers two fingerprint images based on a pair of corresponding control-points. It uses this control-pointpair of pixel locations within the images to translate and rotate the Moving image to the Fixed image.Runtime configuration parameters include:* moving and fixed image data in 8-bits-per-pixel grayscale (preferable but not required)* two-pairs of corresponding control points (pixel coordinates).The fingerprint-image rigid-registration process is performed in two steps:1. Translation of the Moving image to the Fixed image using the "first" pair of control-points (the unconstrained pair)2. Rotation of the Moving image around the Fixed image control-point (the translation "target" location) based on theangle-difference determined by the "second" pair of control-points (the constrained pair).Both final images, a few interim images, and registration metadata generated during the registration processare made available to the using software:* Final registered Moving image* Final registered Fixed image* Registered, padded, overlaid image (colorized)* Registered, padded, Moving image (grayscale)* Padded, Fixed image (grayscale)* Summed, registered, dilated overlaid image (the "blob")* Process metadata available in both text and XML format.The two Final images are registered. They are cropped to the region-of-interest that is the smallest area of "overlap"per the registration. Therefore, these two images have identical width and height which enables analysis using metricslike PSNR (Peak Signal to Noise Ratio).
