Spoof detection using dual-band fluorescence
The technology described in this document can be embodied in a method for preventing access to a secure system based on determining that a subject is an alternative representation of a live person. The method includes illuminating a first subject with electromagnetic radiation using a first wavelength range that cause fluorescence in human tissue. The fluorescence is in a second wavelength range different from the first wavelength range. The method also includes receiving, responsive to illuminating the first subject and using one or more sensors, electromagnetic radiation emitted from the first subject, and determining that the received electromagnetic radiation is outside the second wavelength range. Responsive to determining that the received electromagnetic radiation is outside the second wavelength range, the method further includes identifying the first subject as an alternative representation of a live person, and preventing access to the secure system in response.
INTELLIGENT CAMERA ILLUMINATION AND PROJECTOR
An imaging system, medical microscope, surgical light, robotic system, imaging method, and computer-readable storage medium. The imaging system creates an optimized image of a region to be imaged and includes an irradiation system.

The image processing method includes: a temperature of a light emitter is detected (202); in condition that a temperature difference between a present temperature of the light emitter and an initial temperature exceeds a threshold, a target parameter is acquired (204); and a predetermined operation is performed according to the target parameter (206).
SYSTEM AND METHOD FOR OBJECT AND OBSTACLE DETECTION AND CLASSIFICATION IN COLLISION AVOIDANCE OF RAILWAY APPLICATIONS
A system for detection and identification of objects and obstacles near, between or on railway comprise several forward-looking imagers adapted to cover each different range forward and preferably to be sensitive each to different wavelength of radiation, including visible light, LWIR, and SWIR. The substantially homogeneous temperature along the rail the image of which is included in an imager frame assists in identifying and distinguishing the rail from the background. Image processing is applied to define living creature in the image frame and to distinguish from a man-made object based on temperature of the body. Electro optic sensors (e.g. thermal infrared imaging sensor and visible band imaging sensor) are used to survey and monitor railway scenes in real time.
Apparatus and process for visual recognition
An apparatus and a process improve the ability of computer systems to distinguish genuine from altered or fabricated media depictions of a subject. Three-dimensional depth data of the subject is multiplexed with visual data of the subject to create a tensor data structure. In one aspect, the invention utilizes the tensor to create a unique and characteristic watermark for any segment of the subject's depiction. In another aspect, the invention comprises a deep neural network trained with the tensor to provide enhanced image recognition of genuine depictions of the subject. Embodiments are particularly suited to detect sophisticated alterations and fabrications in photographic and video renditions of public figures.
Image detection scanning method for object surface defects and image detection scanning system thereof
An image detection scanning method for object surface defects and an image detection scanning system thereof are provided. The method includes capturing a test image according to test light, determining whether the test image is normal, generating a coincidence signal if the test image is normal, coinciding the object with the detection position according to the coincidence signal, sequentially moving one of a plurality of areas on a surface of the object to the detection position, providing detection light facing the detection position, the detection light illuminating the detection position with a light incident angle of less than or equal to 90 degrees relative to a normal line of the area located at the detection position, and capturing a detection image of each of the areas sequentially located at the detection position according to the detection light after the object is coincided with the detection position.
Method and device to speed up face recognition
Method to customize an application associated with a television experience based on the recognition of users located in front of a display and in the field of view of a camera, comprising the following steps: an initialization step during which each user is enrolled in a database of a computer system and is defined by a profile referenced by a profile ID and comprising the user name, biometric data and additional personal data, a finding step during which a wide image, acquired by said camera is scanned to isolate at least one user's faces, to define a marking area surrounding it, to memorize the position of said marking areas, a matching step to extract the biometric data from said marking area, to match them with the biometric data of the profiles stored in the database, and to assign the detected profile ID with the marking area. While subsequent identification is requested by the application, the following steps are executed acquiring a wide image with the camera, extracting the areas of said image according to the marking areas, extracting for a particular marking area the biometric data of a face, starting the comparison of the extracted biometric data with the biometric data of the profile ID related to this marking area, and in absence of match, continuing with the other biometric data of the database until one profile is found, transmitting the found profile ID to the application.
