Abstract: A communication system may an optical signal generator and a signal path. The generator may generate one or more optical local oscillator (LO) signals and an optical frequency comb. Optical paths and an optical demultiplexer may distribute the optical LO signal(s) and the frequency comb to photodiodes in one or more access points. The photodiodes may be coupled to antenna radiating elements. The optical paths may illuminate each photodiode using a signal pair that includes one of the optical LO signals and one of the carriers from the frequency comb. The photodiodes may convey wireless signals using the antenna radiating elements at frequencies given by the differences in frequency between the signals in the signal pairs. The radiating elements may concurrently convey the wireless signals with different external devices at different frequencies, with different devices at the same frequency, and/or with the same device at the same frequency.

If a second resolution of a first camera format matches among the supported camera formats matches with the first resolution, the first camera format is selected for capturing the video stream by the camera. Otherwise, a second camera format among the supported camera formats is determined for capturing the video stream so as to maximize a field of view of the video stream relative to other camera formats supported by the camera.

Abstract: According to an example method, a system receives first data representing a polygon mesh. The polygon mesh includes a plurality of interconnected vertices forming a plurality of triangles. The system generates second data representing the polygon mesh. Generating the second data includes traversing the vertices of the polygon mesh according to a traversal order, partitioning the plurality of triangles into a set of ordered triangle groups in accordance with the traversal order, and encoding, in the second data, the set of ordered triangle groups. The system outputs the second data. A position each of the vertices in the transversal order is determined based on (i) a number of previously encoded triangles that are incident to that vertex, and/or (ii) a sum of one or more angles formed by the previously encoded triangles that are incident to that vertex.

Abstract: Novel machine learning (ML) models are introduced for image reconstruction training and inference workflows, which are able to estimate intrinsic components of single view images, including albedo, normal, and lighting components. According to some embodiments, such models may be trained on a mix of real and synthetic image datasets. For training on real datasets, both reconstruction and cross-relighting consistency terms may be imposed. The use of a cross-relighting consistency term allows for the use of multiple images of the same scene—although lit under different lighting conditions—to be used during training. At inference time, the model is able to operate on single or multiple images. According to other embodiments, adversarial training (e.g., in the form of a generative adversarial network (GAN)) may optionally be incorporated into the training workflow, e.g., in order to better refine the re-rendered images from the individual lighting and geometric components estimated by the model.
