Active-pixel image sensor
There is provided an active-pixel image sensor that uses a method of offsetting and interleaving to increase its resolution. In a basic configuration of the active-pixel image sensor, light from one optical transmitter is diffracted to create one diffraction pattern, and then light from another optical transmitter is diffracted to create another diffraction pattern. Light from further optical transmitters may also be diffracted to create further diffraction patterns sequentially after that. These diffraction patterns are offset from one another and then interleaved using time division multiplexing so as to create a single pixel output that has higher resolution than is feasible with an active-pixel image sensor that only utilizes one optical transmitter per pixel or that does not use diffraction patterns to create a larger field of view. |

Dynamic synchronization of frame rate to a detected cadence in a time lapse image sequence
A frame rate is synchronized to a detected cadence in order to generate an output image sequence that is substantially stabilized. In an in-camera process, a camera receives motion data of the camera while the camera captures the sequence of image frames. A dominant frequency of motion is determined and the capture frame rate is dynamically adjusted to match the frequency of detected motion so that each image frame is captured when the camera is at approximately the same position along the axis of motion. Alternatively, in a post-processing process, frames of a captured image sequence are selectively sampled at a sampling rate corresponding to the dominant frequency of motion so that each sampled frame corresponds to an image capture that occurred when the camera is at approximately the same position along the axis of motion. |

Creation of fictitious identities to obfuscate hacking of internal networks
Introduced here are security techniques for networks. More specifically, fictitious identities (also referred to as “bogus identities”) can be willfully created and injected into the network in order to obfuscate those who are not authorized to access the network. For example, such techniques may be used to befuddle hackers attempting to breach an internal network. The fictitious identities can be created by bypassing the operating system of computing device(s) residing within the network and deploying the fictitious identities within an operating system process responsible for implementing a security policy. Such action utilizes a limited amount of memory. The fictitious identities create a false visual of the network that is visible to any threat, regardless of where the threat is located in the network. Moreover, the fictitious identities may not infringe upon the topology of the network or affect the ability of authenticated users to continue using the network. |

Policy compliance verification using semantic distance and nearest neighbor search of labeled content
An online system determines whether a test content item violates a policy of the online system. The online system extracts a semantic from the test content item and determines a distance between the extracted semantic vector and the stored semantic vectors for content items that have been labeled to indicate whether they violate a policy. Using a nearest neighbor search, the online system selects a set of the stored semantic vectors and assigns a weight to the selected semantic vectors that is inversely related to the distances. The online system then determines whether the test content item violates a policy using a weighed voting scheme, where the labels of the stored semantic vectors are aggregated based on their associated weights. The online system may first attempt to match the test content with known bad content and terminate the more complex nearest neighbor search if such a match is found. |
