FINGER VEIN SENSORS AND METHODS OF USING THE SAME
The present disclosure relates to several types of finger vein sensor. In certain embodiments, the finger vein sensor includes: an image sensor, and an infrared light source. Image sensor captures infrared image of finger vein pattern of a finger of a target human. The image sensor faces down and is positioned at top of finger vein sensor. The infrared light source may include a predetermined number of infrared light-emitting diodes (LED), and they are arranged in one or more rows and one or more columns and positioned at bottom of finger vein sensor. The finger is positioned between infrared light source and image sensor. The infrared light from the infrared light source irradiates the finger vertically from the bottom to generate the infrared image of finger vein pattern of the finger on the image sensor, and the image sensor captures the infrared image of finger vein pattern of the finger.
Image processing device and image processing method
Provided is an image processing device including an adjustment unit that adjusts any one of a background image which is a far-infrared image showing a background that does not include an object and a target image which is a far-infrared image showing the object, on the basis of a time change model of an observation pixel value, and an extraction unit that extracts a target region including the object in the target image on the basis of a result of comparison between the background image and the target image after the adjustment is performed.
Shutterless far infrared (FIR) camera for automotive safety and driving systems
A shutterless far-infrared (FIR) camera for advanced driver assistance systems, including at least one optical unit including at least one lens; an FIR sensor coupled to the optical unit and configured to capture FIR images; and an integrated circuit (IC) configured to process the captured FIR images to output an enhanced thermal video stream, wherein the IC further includes: a processing circuitry; and a memory containing instructions that, when executed by the processing circuitry, configure the processing circuitry to perform image corrections including at least a shutterless correction.
IMAGING CONTROL DEVICE, IMAGING APPARATUS, IMAGING CONTROL METHOD, AND PROGRAM
Provided is an imaging control device including: a processor; and a memory connected to or built in the processor.

SYSTEM AND METHOD OF MULTI-LANE ELEVATED BODY TEMPERATURE PREVENTATIVE SCANNING SOLUTION USING GIGE VISION AND TRACKING
A multi-lane elevated body temperature preventative scanning solution using GigE vision and tracking. This multi-lane solution is used to scan and track movement of people through an elevated body temperature scanning solution. When a person enters the frame, their identity (ID) is tracked within the field of view of the thermal camera in a designated scanning area from there it is monitored through the entry and exit of a premise to acquire a preventative temperature screening. Multiple machine learning and tracking routines are used together in this innovative offering.
