Benefits of technology

The patent text describes a method to improve facial recognition by using infrared images. The invention focuses on eliminating certain color components, such as blue and green, from the color image and using only the red component for facial recognition. This helps to improve the accuracy of facial recognition when compared to a gallery of color images. The invention can also identify specific individuals based on their appearance in the color image.

Problems solved by technology

However, conventional facial recognition techniques do not perform well with target images captured using infrared illumination when these target images are compared against a gallery of color images.

Embodiment Construction

[0009]Detecting and subsequently recognizing a face of a target, via a machine, in an uncontrolled environment is challenging, especially in an uncontrolled outdoor environment. First, the target is free to move into, out of, and within a field of view of the camera, at a variety of ranges and any number of other motion factors as would be appreciated. Second, illumination of the target differs by weather, time of day, orientation of the target, objects in the environment, and any number of other illumination factors as would be appreciated. Third, having the target inside a vehicle dramatically increases the challenges by introducing vehicle type, vehicle motion, location of the target in the vehicle, window tinting, reflections, sunroofs, interior lighting, and any number of other vehicle factors as would be appreciated. Other factors provide further challenges to detecting and recognizing faces in the uncontrolled environment.

Abstract

Various implementations of the invention perform facial recognition on a target image compared against a color image from an image gallery, where the target image was acquired by an infrared-sensitive camera of a target that was illuminated with infrared light. According to various implementations of the invention, a blue component and a green component of the pixels in the color image are suppressed or eliminated, and facial recognition is performed between the target image and the color-suppressed image.

Description

FIELD OF THE INVENTION[0001]The invention is generally related to facial recognition techniques and more particularly, to improving facial recognition of a target image compared against a gallery of color images, when the target image was captured from a target that was illuminated with infrared light.BACKGROUND OF THE INVENTION[0002]Conventional facial recognition techniques attempt to match a target image captured from a target against a repository of images (some of which may be color images) of known subjects. In some low-light environments, it may be necessary to illuminate the target in order to capture a better image of the target. In some circumstances, an infrared light source is used to illuminate the target for capture by a camera sensitive to infrared light. This type of illumination avoids certain problems with blinding or scaring the target or alerting the target to the camera's presence in certain low-light environments, including, for example, at night or when the ta...
