Biasing a noise filter to preserve image texture
Embodiments relate to biasing an image noise filter to reduce edge and texture blurring of image data. Pixel values used to determine photometric coefficients for a bilateral filter are modified by offset values. The offset value for a pixel value is determined by applying a high pass filter to the pixel (referred to as the center pixel) and neighboring pixels of the center pixel. By adding the offset value to the center pixel value, the pixel value difference between the neighboring pixels and the center pixel becomes smaller for pixels on the same side of an edge as the center pixel. Thus, pixels on the same side of the edge get more weight in the bilateral noise filter. Conversely, pixels on the opposite side of the edge as the center pixel get less weight in the bilateral filter. As a result, the biased bilateral filter reduces blurring of edges and increases preservation of texture in the image data. |

Anti-spoofing of transparent fake object overlays with optical sensing modules
Optical sensing is provided for anti-spoofing of transparent spoof overlay material using pixel spreading detection. Some embodiments operate in context of an under-display optical fingerprint sensor integrated into an electronic device. An optical scanning system can direct illumination incident on a sensing region, which is redirected, by specular reflection off of a contact surface, onto an optical sensor in a predictable manner. When an object (e.g., finger) is in direct contact with a contact surface, the predictable specular correspondence is maintained. However, when a transparent spoof material is placed between the object and the contact surface, the spoof material produces additional specular and non-specular reflection, resulting in pixel spreading at the optical sensor. Thus, presence of the spoof material can be detected by detecting such pixel spreading. Some embodiments use illumination masking to help facilitate the pixel spreading detection. |

Additionally, the DBMS identifies surplus data in the external data source, which has not been specified by the ingest schema and is different from the queried data defined by the client-requested query schema. The process not only ingests the ingest data fields from the external data source but also the surplus data from the external data source. In response to receiving a query according to a different query schema, DBMS generates a result set that based on the surplus data of the external data source. The result generation is based on the DBMS generating a map of operations, which when performed, generates a result set for the received query regardless whether the query is based on the different query schema. |

The invention relates an electrical device for providing an output depending on an electrical input.

Sensor device
A sensor device including a deflectable membrane made of a 2D nanomaterial, a first optical waveguide for guiding light, disposed adjacent to the membrane and extending along the surface of the membrane at least in a first section, as well as a measuring device for measuring, within the first section the influence of the membrane on an evanescent wave range of the light guided along the first optical waveguide.
