Abstract: In various embodiments, a process for trying on glasses includes determining an event associated with updating a current model of a user's face. In response to the event, using a set of historical recorded frames of the user's face to update the current model of the user's face. The process includes obtaining a newly recorded frame of the user's face, using the current model of the user's face to generate a corresponding image of a glasses frame, and presenting the image of the glasses frame over the newly recorded frame of the user's face.

Abstract: A system and method for scaling a user's head based on estimated facial features are disclosed. In an example, a system includes a processor configured to obtain a set of images of a user's head; generate a model of the user's head based on the set of images; determine a scaling ratio based on the model of the user's head and estimated facial features; and apply the scaling ratio to the model of the user's head to obtain a scaled user's head model; and a memory coupled to the processor and configured to provide the processor with instructions.

Abstract: Methods and systems for optically determining the performance of active components of a device under test (DUT). A portion of the DUT that includes a target active component and an additional active component is illuminated and reflected energy from the target active component and the additional active component is detected by one or more sensors. An analog signal that corresponds to the reflected energy is generated by a processor. An estimated target signal determined based on the analog signal and the second analog signal, where the estimated target signal corresponds to an estimated component of the analog signal that is attributable to the target reflected energy reflected by the target active component. The estimated target signal is then used to determine the performance of the target active component of the DUT.

Abstract: In one embodiment, a method for improving the alignment of CAD data to optical imaging data, such as LSM and LVI images of integrated circuits is disclosed. Image reconstruction techniques are applied to optical images, such as laser voltage images (LVI), laser scanning microscope (LSM) images, or emission images, to produce reconstructed images which may have higher resolution, increased signal-to-noise, or other enhancements. Multiple CAD pattern layers are processed to generate second CAD images more closely corresponding to the appearance of the reconstructed images. Alignment of the reconstructed images to the second CAD data may be substantially more accurate and precise than alignment of the initial optical images to the CAD data—in some cases this improvement may make the difference between a successful alignment and a failed alignment.
