The execution mechanism includes a mechanical arm and a probe. The ultrasound scanning control method includes controlling the mechanical arm to drive the probe to move according to a set scanning trajectory for performing an ultrasound scanning detection on a part to be examined. Once an actual pressure value between the probe and the part to be examined in each control cycle is sensed using the force sensor, a pressure value between the probe and the part to be examined is controlled to be a constant value based on the actual pressure value.

Abstract: An image processing device is provided. The device includes an electronic image stabilization (EIS) module and an image signal processing (ISP) module. The EIS module is configured to determine EIS information for a video frame based on motion information that corresponds to the video frame, wherein the EIS information is associated with the target region and the margin region of the video frame.

Abstract: An electronic device controlling method and a user registration method are provided. In the electronic device controlling method, when a target device receives a first and a second control commands which are identical, but performed by different users simultaneously or separately, the target device performs a first predetermined operation based on an identity of the user performing the first control command, and performs a second predetermined operation based on an identity of the user performing the second control command. In the user registration method, a user registered identity model corresponding to a user to be registered is established according to identity information of the user, and is mapped to a user profile comprising a relationship between the control commands and the predetermined operations. By acquiring the registered information, the target device is able to perform the user dependent operations.

Abstract: A 3D face model construction method is disclosed herein, which includes a training step and a face model reconstruction step. In the training step, a neutral shape model is built from multiple training faces, and a manifold-based approach is proposed for processing 3D expression deformation data of training faces in 2D manifold space. In the face model reconstruction step, first, a 2D face image is entered and a 3D face model is initialized. Then, texture, illumination and shape of the model are optimized until error converges. The present invention enables reconstruction of a 3D face model from a single face image, reducing the complexity for building the 3D face model by processing high dimensional 3D expression deformation data in a low dimensional manifold space, and removal or substituting an expression by a learned expression for the reconstructed 3D model built from the 2D image.

Abstract: A system for copying document/objects in shared libraries via a copy command is disclosed. The COPY command provides four different options for copying and replacing documents located in shared libraries. The simple copy option allows a document to be created in a target library using an existing document in a source library. The option optionally permits a document from a source library to be copied to a folder document in the target library. The replace option provides for the replacement of the IDP and document contents of a document in a target library with the IDP and document contents of a source document. The check-out option provides for the placement of a document in a target library while locking the document in the source library to prevent changes. The check-in option provides for the return of a previously checked out document to a library.
