Disclosed is a method and apparatus for blurring a preview picture and storage medium. Portrait recognition is performed on a first preview picture to determine information of a target portrait in the first preview picture. The information of the target portrait includes an area and position of the target portrait. A target region to be protected is determined according to the information of the target portrait. In switching preview pictures, blurring is performed on a region, except the target region, in a second preview picture.

A liveness detection method includes: controlling a display screen to display a color according to a predetermined color display sequence, the color display sequence including at least two different colors; capturing an image of a target object in a color display process of the display screen; acquiring a color change sequence of a face of the target object in the image over time; and determining whether the target object is live based on a matching relationship between the color display sequence and the color change sequence.

A vehicular vision system includes a camera disposed at a vehicle and having a field of view rearward of the vehicle, a light source disposed at the vehicle and operable to emit light, and a control including an image processor. The control, responsive to detection of the object present in the field of view of the camera, determines a region of the field of view of the camera at which a detected object is located. The control determines an illumination level at the detected object and, responsive to the determined illumination level at the detected object being greater than an upper threshold level or less than a lower threshold level, controls the respective individually controllable light segment of the light source for that region of the field of view of the camera at which the detected object is located to adjust intensity of light emitted by that light segment.

According to one embodiment, a light source includes a plurality of light-emitting elements each including one or more surface-emitting lasers; and a plurality of detecting elements located on a same substrate as the light-emitting elements. The detecting elements individually detect quantities of output light of the light-emitting elements.

Systems and methods for blue light adjustment with a wearable display system are provided. Embodiments of the systems and methods for blue light adjustment can include receiving an eye image of an eye exposed to an adjusted level of blue light; detecting a change in a pupillary response by comparison of the received eye image to a first image; determining that the pupillary response corresponds to a biometric characteristic of a human individual; and allowing access to a biometric application based on the pupillary response determination.

An image recognition device, an image recognition method, and an image recognition unit which can achieve touch recognition with high accuracy. An image recognition device includes an image processing unit which carries out touch recognition, based on an image acquired by an image capturing device, the image capturing device being arranged in a second orthant or a third orthant, and based on a distance between a missing part generated on an image display surface due to light from a detection image display device being blocked by an object when the object is situated between the detection image display device and the image display surface, and the detection image situated on an epipolar line decided based on a positional relation between the image capturing device and the detection image display device and passing through the missing part, and displayed on the object.

A method, computer system, and a computer program product for visual pattern recognition is provided. The present invention may include capturing one or more images of a reference object and an object under inspection. The present invention may then include processing the one or more images of the reference object and the object under inspection. The present invention may lastly include determining that the reference object and the object under inspection are not a match.

A public area defense system, comprising a non-lethal reactive deterrence defense subsystem, an optical subsystem operably coupled to and in communication with the non-lethal reactive deterrence defense subsystem, and an acoustic subsystem operably coupled to and in communication with the non-lethal reactive deterrence defense subsystem. The public area defense system may further comprise a computer system in communication with each of the non-lethal reactive deterrence defense subsystem, the optical subsystem, and the acoustic subsystem, wherein each of the non-lethal reactive deterrence defense subsystem, the optical subsystem, and the acoustic subsystem are operable to interact with an actor

A biological information detection device includes a light source, an image capturing device, and one or more arithmetic circuits. The light source projects dots formed by light onto a target including a living body. The image capturing device includes photodetector cells and generates an image signal representing an image of the target onto which the dots are projected. The one or more arithmetic circuits detect a portion corresponding to at least a part of the living body in the image by using the image signal and calculate biological information of the living body by using image signal of the portion.

This object detection device is provided with: an output unit; a plurality of detection units; a data acquisition unit; and an object information confirmation unit. The output unit outputs measurement light Lm towards an object. Each of the plurality of detection units detects, as a signal representing the distance to the object present in an observed area and the shape of the object, the reflected light generated as a result of the measurement light being reflected by the object. The data acquisition unit acquires detection signal waveforms W representing changes in the intensities of second signals over time. The object information confirmation unit confirms the range of the presence of the object by determining that any two or more of the detection units correspond to the same object, or correspond to different objects, on the basis of the detection signal waveforms.
