Effective prediction using partition coding
The way of predicting a current block by assigning constant partition values to the partitions of a bi-partitioning of a block is quite effective, especially in case of coding sample arrays such as depth/disparity maps where the content of these sample arrays is mostly composed of plateaus or simple connected regions of similar value separated from each other by steep edges. The transmission of such constant partition values would, however, still need a considerable amount of side information which should be avoided. This side information rate may be further reduced if mean values of values of neighboring samples associated or adjoining the respective partitions are used as predictors for the constant partition values. |

Automated extraction of behavioral profile features
Actions in an electronic environment are monitored during a learning period and behavior profiles generated using feature values for those actions. Subsequent behavior can be compared against the profiles to track the anomalies, or mismatches between features of incoming events and features of the profiles.

If any normalization sufficiently decreases the mismatch rate, the feature will not be excluded from the behavior profile. Any exclusion candidate feature which does not have an adequate mismatch value after normalization can be removed from tracked features of the corresponding profile. The behavior profile can be used to detect anomalous behavior that deviates from values of the behavior profile. |

Cyber companion: attaching a secondary message to a primary one
Using Unary alphabet to express a cyber message, the identities of the message bits can be used to carry a companion message. The P (prime) message, and the C (companion) message can be related or unrelated. The C message may be used to authenticate, or to invalidate the P message and its writer. While the P message may be in the open, the C message may be limited to key-holding readers. The C message may be modified by successive readers while leaving the P message unchanged. A wide range of applications is available on account of the simple idea of writing the primary message via bit-count (ignoring bit identities), leaving the identity assignments to carry the companion message. Alice and Bob may exchange a large number of primary messages, where for most of them the companion message says: “ignore the primary message”. While both Alice and Bob, reading the companion message will regard only the proper messages, an eavesdropper will be thoroughly confused, or receive a misleading impression of the conversation between the two. If the C message is generated via a private key, then a reader of the P+C messages will be able to authenticate the prime message and its writer with the respective public key. |

Once the system has identified an object and its location, the system may prompt the person to look directly at the object. The camera may then record an image of the user looking at the object. The processor may analyze the image to determine the location of the user's head and, combined with the known location of the object and the known location of the camera, determine the direction that the user is facing. This direction may be treated as a reference value, or “ground truth.” The captured image may be associated with the direction, and the combination may be used as training input into an application. |

Method and system for enhanced ultrasound image visualization by detecting and replacing acoustic shadow artifacts
An ultrasound probe acquires ultrasound images at different directions, such as by performing beam steering. A processor analyzes the ultrasound images to detect acoustic shadow artifacts. The processor marks the acoustic shadow artifacts detected in one or more regions of one or more of the analyzed ultrasound images. The processor constructs a compound image based on unmarked regions of the analyzed ultrasound images. The processor presents the constructed compound image at a display system. The processor applies an image recognition technique to identify whether a region of an ultrasound image includes a dark area. The processor compares image data of the region corresponding with a same location in each of the ultrasound images and detects the acoustic shadow artifacts in the region having the identified dark area if at least one of the analyzed ultrasound images does not include the dark area at the region corresponding with the same location. |

Bonded wafer metrology
Wafer edge profile images are analyzed at locations around a bonded wafer, which may have a top wafer and a carrier wafer. An offset curve is generated based on the wafer edge profile images. Displacement of the top wafer to the carrier wafer is determined based on the offset curve. The wafer edge profile images may be generated at multiple locations around the wafer. The wafer edge profile images may be shadowgram images. A system to determine displacement of the top wafer to the carrier wafer can include an imaging system connected with a controller. |

Image processing systems and methods
A method of capturing writing or drawing on a whiteboard comprises inputting camera data for a succession of image frames of the whiteboard, and processing data from said image frames to remove parts of the image frames corresponding to parts of a user or user pen writing or drawing on the whiteboard. The processing involves filtering to distinguish between i) motion of the user/user pen parts in the image frames, and ii) writing/drawing image information in the image frames which appears or changes during said writing or drawing but which is thereafter substantially unchanging. The filtered data defines captured writing or drawing from the whiteboard. |

Digital image scaling
Examples include computing devices, processes, and/or machine-readable storage mediums. Examples analyze a region of pixels for a digital image to determine a set of diagonal direction pixel differences corresponding to a target pixel. Examples analyze the region of pixels to determine diagonal variances corresponding to the target pixel. Examples scale the digital image by processing the target pixel into a set of subpixels based at least in part on the set of diagonal direction pixel differences and the diagonal variances. |

Image warping in an image processor
A device that includes integrated circuit includes a tiler circuit, a grid generator, and a warper circuit. The tiler circuit divides the distorted input image data into a plurality of image tiles and stores the image tiles into a memory device. Each image tile is an M×N array of pixel samples where M and N are greater than 1. The grid generator produces a mesh grid that describes a mapping of first pixel locations of the distorted image data to second pixel locations of the corrected image data. The warper circuit reads one or more of the image tiles from the memory device based on the mesh grid and interpolates a warped output image from the image tiles read from memory. |
