Abstract: Systems and techniques are provided for generating one or more models. For example, a process can include obtaining a plurality of input images corresponding to faces of one or more people during a training interval. The process can include determining a value of the coefficient representing at least the portion of the facial expression for each of the plurality of input images during the training interval. The process can include determining, from the determined values of the coefficient representing at least the portion of the facial expression for each of the plurality of input images during the training interval, an extremum value of the coefficient representing at least the portion of the facial expression during the training interval. The process can include generating an updated bounding value for the coefficient representing at least the portion of the facial expression based on the initial bounding value and the extremum value.

In certain embodiments, the device for testing a biological specimen includes a receiving mechanism to receive a carrier, a camera module arranged to capture imagery of the carrier, and a processor. Some examples of the processor can detect a calibration mode trigger. In calibration mode, the processor can divide the captured imagery into segments and selectively perform one or more calibration procedures for each segment. Then, the processor records a calibration result for each segment.

Abstract: Disclosed are verification techniques that can be implemented by a device that conducts biological tests to verify that the specimen holding area carries a valid biological specimen. In certain embodiments, the testing device includes a receiving mechanism to receive a carrier, and the carrier includes a holding area that is to carry or to be exposed to a biological specimen. The device can also include a camera module arranged to capture imagery of the carrier, and a processor. In some examples, the processor can capture the imagery of the carrier and identify a visual cue on the carrier. Then, the processor can verify, based on a manner of how the visual cue is displayed in the captured imagery, whether the holding area carries a valid biological specimen.
