摘要： An apparatus includes a processor that extracts a plurality of feature points from a biological image, calculates a feature value of each of the plurality of extracted feature points, normalizes the calculated feature values to values of N levels (N is any natural number) based on a distribution of the feature values, and translates each normalized feature value to binary data by setting a number of bits corresponding to the normalized feature value to one of two digits in accordance with to a given order to make the normalized feature value and the number of bits with the one digit proportional to each other.

摘要： A ridge flow based fingerprint image quality determination can be achieved independent of image resolution, can be processed in real-time and includes segmentation, such as fingertip segmentation, therefore providing image quality assessment for individual fingertips within a four finger flat, dual thumb, or whole hand image. A fingerprint quality module receives from one or more scan devices ridge-flow-containing imagery which can then be assessed for one or more of quality, handedness, historical information analysis and the assignment of bounding boxes.

摘要： An electronic device and method for measuring biometric information are provided. The electronic device includes at least one light emitter; light receiver; and a processor. The processor is configured to emit light outside of the electronic device through the at least one light emitter, obtain, through the light receiver, light reflected by an external object among the emitted light, obtain a signal generated based on at least a portion of the reflected light and corresponding to the external object, output guide information related to a location of the external object when the signal satisfies a first designated condition, and obtain biometric information about the external object when the signal satisfies a second designated condition. When a finger of a user finger of the electronic device is not accurately located at a bio sensor, by guiding an accurate grip location, biometric information about the user can be accurately measured.

摘要： Methods, systems and articles of manufacture for a portable electronic device that uses biometric content to determine an orientation in which a display device is presenting content are disclosed. Example electronic devices include a display device, a biometric sensor to capture a biometric sample, and an orientation determination tool to determine a device orientation relative to a user based on the biometric sample. Example devices further include an orientation adjustment tool to change a content orientation in which the display device of the portable electronic device presents content based on the determination of the device orientation of the at least one of the display device and the portable electronic device. In some examples, the biometric sensor is a fingerprint sensor or an image sensor.

摘要： A system performs processing of biometric information to create multiple templates. This allows biometric systems to be flexible and interact with a plurality of vendors' technologies. Specifically, a biometric sample is captured from a sensor and transmitted to a processing component. The biometric sample is then processed by a first algorithm to yield a biometric template and the template is stored and associated with a record identifier. The biometric sample is also processed by a second algorithm to yield a second template. The second template is stored and associated with the record identifier.

摘要： The present invention provides an image brightness non-uniformity correction method and an image brightness correction device therefor. The image brightness non-uniformity correction method includes the steps of: (A) generating an initial input image having pixels arranged in a matrix, wherein each pixel has a corresponding pixel brightness and the initial input image has non-uniform brightness; (B) performing a pre-processing procedure on the initial input image, to generate a pre-processed image; (C) performing an image gradient correction procedure on the pre-processed image, to eliminate non-uniformity of the brightness of the initial input image; and (D) outputting an output image having an uniformity-processed brightness.
