More Information
Summary:Methods, systems, and computer readable media for fingerprint capture and verification are described. A camera is utilized to capture a set of images at a first resolution. A focal length for at least one object in the plurality of images is verified to be greater than a minimum focus threshold. The images are converted to corresponding binary images. A finger is identified in the one or more binary images. A still image of the finger is captured at a second and higher resolution. Image processing filters are applied to the still image to generate a fingerprint image which is transmitted to an application server for verification.
