Abstract: A system and method for obtaining a biometric image such as a ten-print fingerprint impression is provided. The system and method can include a live scanner having a platen and a finger guide coupled to the platen. The finger guide can be used to guide positioning of up to four fingers at a time onto the platen, and can include a physical barrier for separation of fingers or thumbs. The finger guide and physical barrier allow a determination of whether a left or right hand is placed on the platen. Fingerprint images can be separated into individual fingerprint images that can be placed onto corresponding areas of a fingerprint card.

Abstract: A system and method for obtaining a biometric image such as a ten-print fingerprint impression is provided. The system and method can include a ten-print scanner having a platen and a finger guide coupled to the platen. The finger guide can be used to guide positioning a finger slap of four fingers at a time onto the platen. The ten-print scanner can also include at least four indicators that indicate an acceptable scan condition of each finger of a finger slap in response to a detected finger slap image.

Abstract: A method of reliably capturing biometric print images includes determining the print quality of a scanned image, detecting prints in the scanned image, and determining whether the scanned image is ready for capture. The method includes filtering the scanned image, binarizing the filtered image, detecting print area, print contrast, and print shape of the binarized image, and separating the print image into individual print images based on the print area, contrast, and shape. Each individual print image is classified base on a predetermined quality threshold and a quality classification of each individual print image is indicated. The method includes a predetermined capture delay time period, quality time period, and scanner timeout period. An operator can annotate issues regarding missing or unacceptable print images. A system of reliably capturing biometric print images includes a scanner including a print capture manager, a computer, and a communication link between the computer and scanner.

Abstract: A method and system of obtaining a ten-print plain impression fingerprint includes scanning a print image, processing the scanned image, separating the processed image into individual fingerprint images, and determining how many print images have been scanned. The method also includes comparing the print image to a previously scanned print image, quality classifying the separated images, indicating a quality classification of the print image based on the classifying step, and determining whether the print image is of a good quality. The system can include a ten-print scanner having a finger guide and a platen used to position four finger slaps onto the platen.

Abstract: A composite image of a finger rolling relative to an imaging device is generated by stitching together image data from a plurality of image frames. The areas of each image that contain useful fingerprint information are identified and the speed of movement of the finger relative to the imaging path is determined. The frames are stitched together in sequence and data for pixels near the boundary between adjacent images is blended, so that values for those pixels are determined based on redundant data from both adjacent images. The extent of blending is based at least in part on movement speed of the finger, so that as speed increases blending is applied to an increasing number of the pixels in the boundary area.
