A collation device includes a processor configured to, by executing a program: (a) acquire a photographed image including a collation area provided on an object and a reference position area that serves as a reference for a position of the collation area; (b) detect the reference position area from the photographed image; (c) set a peripheral image area in the photographed image based on the reference position area and predetermined relative coordinates; and (d) detect the collation area in the peripheral image area.

A method and system for analyzing and/or estimating a metabolite profile of a subject. A digital image of a sample of feces of the subject is received by one or more processors. The digital image and/or one or more features extracted from the digital image is provided as input to a trained machine learning model which is configured to output a classification based on said input digital image and/or one or more features extracted from the digital image. Data indicative of one or more properties of the metabolome of the subject based on the output image classification is determined by the one or more processors.

Methods, apparatus, systems, and articles of manufacture to determine the load of a vehicle via camera-based height measurement are disclosed herein. An example vehicle described herein includes a suspension assembly associated with a wheel, a first feature, a first camera, and a processor to execute instructions to capture, via the first camera, a first image including the first feature and a second feature, the first feature and a second feature having a first spatial relationship in the first image, capture, via the first camera, a second image including the first feature and the second feature, the first feature and the second feature having a second spatial relationship in the second image, and determine, based on a difference between the first spatial relationship and the second spatial relationship, a deflection of the suspension assembly.

In example implementations, an apparatus is provided. The apparatus includes a moveable stage, a print cartridge, a camera, and a processor. The moveable stage is to hold a well plate. The print cartridge holder is to hold a print cartridge that includes a print die over the moveable stage. The camera is located above the movable stage and the print cartridge holder. The camera is positioned such that the movable stage and the print die are within a field of view of the camera. The processor is to calculate a first offset a first offset of the well plate and a second offset of the print die. The movement of the movable stage is controlled by the processor in accordance with the first offset and the second offset.

The present disclosure relates to a two-dimensional (2D) code display method, apparatus, device, and medium. The 2D code display method includes: receiving a 2D code display operation for triggering display of a 2D code image corresponding to a target content, wherein the target content belongs to a first application; in response to the 2D code display operation, displaying the 2D code image including a first primary positioning point and a second primary positioning point that are arranged to overlap, wherein the first primary positioning point is above the second primary positioning point and has a preset color, and wherein the second primary positioning point has a representative color of the first application.
