    Abstract: Image Signal Processing (ISP) optimization framework for computer vision applications is disclosed. The tuning of the ISP is performed automatically and presented as a nonlinear multi-objective optimization problem, followed by solving the problem using an evolutionary stochastic solver. An improved ISP of the embodiments of the invention includes at least features of search space reduction for reducing a number of ISP configurations, remapping the generated population to the reduced search space via mirroring, and global optimization function processing, which allow tuning all the blocks of the ISP at the same time instead of the prior art tuning of each ISP block separately. Also shown that an ISP tuned for image quality performs inferior compared with an ISP trained for a specific downstream image recognition task.

    Abstract: Commercially available gas filters are too large for mobile form-factor gas sensors. These sensors require filters with planar dimensions in the millimeter range and thicknesses of 1 mm or less and combined with long term and harsh conditions survivability. Furthermore, custom filters made small enough to be applied onto mobile form-factor gas sensors are generally not specific enough to support multi-gas detection. This invention describes a novel structured filter: (1) derived from principles of macroscale gas separation columns, (2) made compact enough to be utilized at millimeter scale and microscale levels, and (3) made compatible with mobile requirements and some methodology for usage in micro gas spectroscopy platforms.

    Abstract: The present disclosure relates to methods and apparatus for graphics processing. The apparatus may configure a plurality of billboards associated with a viewpoint of a first frame of a plurality of frames, the plurality of billboards being configured in one or more layers at least partially around the viewpoint, the configuration of the plurality of billboards being based on one or more volumetric elements between at least one of the plurality of billboards and the viewpoint. The apparatus may also render an image associated with each of the one or more volumetric elements between at least one billboard of the plurality of billboards and the viewpoint, the rendered image including a set of pixels. The apparatus may also store data in the at least one billboard based on the rendered image associated with each of the one or more volumetric elements, the data corresponding to the set of pixels.

    Abstract: Systems and techniques are provided for determining environmental layouts. For example, based on one or more images of an environment and depth information associated with the one or more images, a set of candidate layouts and a set of candidate objects corresponding to the environment can be detected. The set of candidate layouts and set of candidate objects can be organized as a structured tree. For instance, a structured tree can be generated including nodes corresponding to the set of candidate layouts and the set of candidate objects. A combination of objects and layouts can be selected in the structured tree (e.g., based on a search of the structured tree, such as using a Monte-Carlo Tree Search (MCTS) algorithm or adapted MCTS algorithm). A three-dimensional (3D) layout of the environment can be determined based on the combination of objects and layouts in the structured tree.

    Abstract: Aspects include piezoelectric acoustic transducers and systems for acoustic transduction. In some aspects, an acoustic transducer is structured with a silicon substrate having a top surface and a bottom surface, where the top surface has a first portion and an edge along the first portion associated with an acoustic aperture. The transducer has a first silicon oxide layer disposed over the first portion of the top surface of the silicon substrate, a polysilicon layer disposed over the first silicon oxide layer, and a second silicon oxide layer disposed over the polysilicon layer. A cantilevered beam comprising a fixed end, a deflection end, a top surface, and a bottom surface, has a first portion of the bottom surface at the fixed end disposed over the second silicon oxide layer, where a second portion of the bottom surface at the deflection end is formed over the acoustic aperture. In some aspects. transducer elements are reconfigurable between parallel and serial configurations depending on a system operating mode.
