sod_img sod_minutiae(sod_img input, int *pTotal, int *pEp, int *pBp);
Extracts ridges and bifurcations from a fingerprint image. Minutiae extraction is applied to skeletonized fingerprint image obtained from sod_hilditch_thin_image().
A typical input picture should look like the following after processing:
Input grayscale fingerprint
The input image to be processed which must be skeletonized via a prior successful call to sod_hilditch_thin_image(). The image can be loaded from disk using sod_img_load_from_file(), from memory (i.e. network socket) via sod_img_load_from_mem() or dynamically created via sod_make_image().
OUT/OPTIONAL: If set, this will hold the total number of black points.
OUT/OPTIONAL: If set, this will hold the total number of ending points.
OUT/OPTIONAL: If set, this will hold the total number of bifurcations.
Processed image is returned in an instance of the sod_img object. if something goes wrong during processing, then an empty image is returned via sod_make_empty_image(). Once done, you must release the memory allocated to this object via sod_free_image() to avoid memory leaks.
