Systems and methods for utilizing living entities as markers for virtual content in an augmented reality environment are discussed herein. The virtual content may comprise objects, surfaces, textures, effects, and/or other content visibly manifested in views of the augmented reality environment. In some implementations, the virtual content may comprise an avatar and/or other full- or partial-body virtual content object depicted based on the living entity. A living entity and multiple linkage points for the living entity may be detected within the field of view of a user. Based on the arrangement of the linkage points, virtual content may be rendered and appear superimposed over or in conjunction with a view of the living entity in the augmented reality environment. In some implementations, the rendering of virtual content in the augmented reality environment may be triggered by the arrangement of the multiple linkage points for a given living entity.

Disclosed are devices and methods for analyzing an analyte, such as white blood cells in liquid samples.

A quality check module for characterizing a specimen and/or a specimen container including stray light compensation. The quality check module includes an imaging location within the quality check module configured to receive a specimen container containing a specimen, one or more image capture devices configured to capture images of the imaging location from one or more viewpoints, and one or more light sources configured to provide back lighting for the one or more image capture devices, and one or more stray light patches located in an area receiving stray light from the one or more light sources enabling stray light affecting the images to be compensated for and to provide a stray light compensated image. Calibration methods, methods of characterizing a specimen, specimen testing apparatus including a quality check module, and specimen container carriers including one or more stray light patches are provided, as are other aspects.

Systems and methods for predicting items within content and using improved, fine-grained image classification techniques to produce images used to identify consumer products in the real-world by allowing for the recognition of a product using an image captured under a variety of conditions and environments, such as angles, lighting, camera settings, and the like.

The present disclosure provides a system and method for temperature measurement. The method may include obtaining a thermal image of an object acquired by a thermal imaging device; identifying, in the thermal image, a first portion of the thermal image corresponding to a first target region of the object; determining, based on the first portion of the thermal image, a highest temperature of the first target region of the object; determining a target position in the first target region of the object, the target position being associated with the highest temperature; and marking, in a target image associated with the object, the target position.

The present disclosure generally relates techniques for audio-assisted enrollment of biometric features. In some embodiments, methods and devices for assisting users with enrollment of biometric features, using spatial audio cues, are described.

The technology described herein includes a method that includes obtaining a set of color-coded sequences, each of which includes a sequence of colors. Each color-coded sequence has auto-correlation properties characterized by a merit factor larger than a first predetermined threshold, and cross-correlation properties among the color-coded sequences characterized by a demerit factor lower than a second predetermined threshold. A color-coded sequence is randomly selected from the set of color-coded sequences. A subject is illuminated in accordance with the sequence of colors in the selected color-coded sequence. A sequence of images of the subject are captured and are temporally synchronized with illumination by the color-coded sequence. A filtered response image is generated from the sequence of images by a matched filtering process. Based on the filtered response image, it is determined that the subject is an alternative representation of a live person. In response, access to a secure system is prevented.
