Implements a Match-on-Host driver for the FocalTech FT9362 fingerprint sensor (USB 0x2808:0xc652). The driver uses FpDevice with a custom NCC-based matcher instead of NBIS, as the 64x80 sensor at 188 DPI does not yield enough minutiae for reliable NBIS matching. Enroll captures 10 images stored individually in FpPrint as a raw byte array. Verify performs a single capture and computes normalized cross-correlation with a ±10px search window against each enrolled template; the maximum NCC score across all templates is compared against a threshold of 0.50 to report match or no-match. Identify applies the same NCC approach across all prints in the gallery and returns the best-matching one above the threshold. Add an umockdev driver test using a synthetic pcapng recording (gradient image, NCC=1.0) that covers open, enroll (10 stages), and verify. |
