An electronic device with a display and a fingerprint sensor may authenticate a user for a respective function. While a respective function of the device is in a locked state, the device displays a graphical element on the display, the graphical element indicating a first direction of finger movement that enables unlocking of the respective function. While displaying the graphical element, the device detects an input that includes movement of a finger in the first direction over the fingerprint sensor and determines whether the input meets unlock criteria based at least in part on fingerprint information of the finger detected by the fingerprint sensor during the input. In accordance with a determination that the input meets the unlock criteria, the device unlocks the respective function; and in accordance with a determination that the input does not meet the unlock criteria, the device maintains the respective function in the locked state.

Embedded authentication systems in an electronic device

An electronic device with a display and a fingerprint sensor displays a fingerprint enrollment interface and detects, on the fingerprint sensor, a plurality of finger gestures performed with a finger. The device collects fingerprint information from the plurality of finger gestures performed with the finger. After collecting the fingerprint information, the device determines whether the collected fingerprint information is sufficient to enroll a fingerprint of the finger. When the collected fingerprint information for the finger is sufficient to enroll the fingerprint of the finger, the device enrolls the fingerprint of the finger with the device. When the collected fingerprint information for the finger is not sufficient to enroll the fingerprint of the finger, the device displays a message in the fingerprint enrollment interface prompting a user to perform one or more additional finger gestures on the fingerprint sensor with the finger.

A device for capturing rendered text is described. The device incorporates one or more visual sensors that receive visual information as a part of capturing rendered text. The visual sensors are collectively capable of capturing both text that is permanently printed on a page, and text that is displayed transitorily on a dynamic device. The device further incorporates a visual information disposition subsystem for disposing of visual information received by the visual sensors. The device further incorporates a package that bears the visual sensors and the visual information disposition subsystem, and is suitable to be held in a human hand.

Depth pictures from a plurality of viewing angles are projected into a single viewing angle, making it possible to have pixel-wise joint filtering to be applied to all projected depth values. This approach enables to suppress the noise in the depth map data and provides improved performance for a view synthesis.

Apparatus, a method and a computer program for video coding and decoding

An apparatus and method for motion vector prediction for a current block in a picture are disclosed. In video coding systems, the spatial and temporal redundancy is exploited using spatial and temporal prediction to reduce the information to be transmitted. Motion Vector Prediction (MVP) has been used to further conserve the bitrate associated with motion vector. In conventional temporal MVP, the predictor is often based on a single candidate such as the co-located motion vector in the previous frame/picture. If the co-located motion vector in the previous frame/picture does not exist, the predictor for the current block is not available. A techniquefor improved MVP is disclosed where the MVP utilized multiple candidates based on co-located motion vectors from future and/or past reference pictures. The candidates are arranged according to priority order to provide better availability of MVP and also to provide more accurate prediction. Furthermore, the MVP technique disclosed can be operated in a closed-loop fashion so that no additional side information or minimum additional side information is required.

Method and apparatus of temporal motion vector prediction

A method and apparatus for deriving a motion vector predictor (MVP) for a motion vector (MV) of a current block of a current picture in Inter, or Merge, or Skip mode. The method selects a co-located block corresponding to a co-located picture and receives one or more reference motion vectors (MVs) of one or more co-located reference blocks associated with the co-located block. The method also determines a search set and determines a search order for the search set, if the search MV corresponding to the given reference list is not available, the search order then searches the search MV corresponding to a reference list different from the given reference list. Finally, the method determines the MVP for the current block based on the search set and the search order and provides the MVP for the current block.

High Efficiency Video Coding (HEVC) is an emerging international video coding standard developed by the Joint Collaborative Team on Video Coding (JCT-VC). Compared to H.264/AVC, HEVC has achieved substantial compression performance improvement. During the HEVC standardization, we proposed several motion vector coding techniques, which were crosschecked by other experts and then adopted into the standard. In this paper, an overview of the motion vector coding techniques in HEVC is firstly provided. Next, the proposed motion vector coding techniques including a priority-based derivation algorithm for spatial motion candidates, a priority-based derivation algorithm for temporal motion candidates, a surrounding-based candidate list, and a parallel derivation of the candidate list, are also presented. Based on HEVC test model 9 (HM9), experimental results show that the combination of the proposed techniques achieves on average 3.1% bit-rate saving under the common test conditions used for HEVC development.

Motion Vector Coding in the HEVC Standard

A method and apparatus for deriving MVP (motion vector predictor) for a block for three-dimensional video coding or multi-view video coding are disclosed. Embodiments according to the present invention replace an unavailable inter-view MV of one neighboring block with a disparity vector derived from depth data of a subset of a depth block corresponding to one neighboring block. A method and apparatus for generating additional candidates for motion vector prediction associated with Merge mode or AMVP (Inter) mode for a block are disclosed. Embodiments according to the present invention generate one or more additional MVP candidates to add to the MVP list if the MVP list size is less than a given list size. The additional MVP candidates are generated either by reducing precision of an available MVP in the MVP list or by adding an offset to the available MVP in the MVP list.

Method and apparatus of motion and disparity vector derivation for 3d video coding and hevc

An apparatus and method for deriving a motion vector predictor or a motion vector predictor candidate or a motion vector or a motion vector candidate for a current block are disclosed. In video coding systems, the spatial and temporal redundancy is exploited using spatial and temporal prediction to reduce the information to be transmitted or stored. Motion Vector Prediction (MVP) has been used to further conserve the bitrate associated with motion vector coding. The MVP technique being developed for the current HEVC only considers the motion vector having the same reference list and the same reference picture index as the current block to be an available spatial motion vector predictor candidate. It is desirable to develop a MVP scheme that can improve the availability of the motion vector predictor candidate based on motion vectors from the spatially neighboring block. Accordingly, an apparatus and method for determining a motion vector predictor or motion vector predictor candidate or motion vector or motion vector candidate for a current block based on motion vectors associated with reference pictures in list 0 and list 1 of a neighboring block are disclosed. The improved MVP scheme may reduce motion vector residues and consequently the coding efficiency can be improved. Furthermore, the MVP scheme is based on a priority order so that the predictor can be derived at the decoder using decoded information without side information.
