Abstract: Several techniques for video encoding and video decoding are described. One example method includes performing a conversion between a subpicture in a video picture of a video and a bitstream of the video according to a rule. The rule specifies that multiple syntax elements are used to specify usage of a reference picture resampling tool.

Abstract: The disclosure provides a multi-object tracking algorithm based on an object detection and feature extraction combination model, including the following steps: S1, adding an object appearance feature extraction network layer behind a prediction feature layer of an object detection tracking network having an FPN structure; S2, calculating object fused loss of the object detection tracking network having the FPN structure and added with the object appearance feature extraction network layer; S3, forming a feature comparison database utilizing a neural network during multi-frame objection detection and tracking process; and S4, comparing current image object appearance features with features in the feature comparison database, drawing an object trajectory if the objects are uniform; else adding the current image object appearance features into the feature comparison database to form a new feature comparison database, and then repeating steps S2 and S3.

Abstract: A computer implemented tactile user interface (TUI) and a method of manipulating objects with a virtual magnet are provided. The TUI includes a display comprising a touch-screen. The display is configured for displaying a set of graphic objects, each graphic object representing a respective one of a set of items, such as documents, e.g., text documents or images. A virtual magnet is caused to move on the display, in response to touching on the touch-screen, e.g., by dragging a finger or other implement across. The magnet is associated with a particular function command such that a subset of the graphic objects exhibits a response to the virtual magnet (e.g., is caused to move, relative to the virtual magnet or exhibits another visible response), each graphic object in the subset moving or otherwise responding as a function of an attribute of the underlying item represented by the graphic object.

Abstract: A display system suitable for controlling operations of a multifunction device, such as a printer, and a method which makes use of the display system are disclosed. The display system includes a front panel configured for selectively displaying a local user interface and being touch sensitive for controlling an associated device based on touch selectable graphic objects displayed on the local user interface. A rear panel is configured for selectively displaying the local user interface, which is viewable through the front panel. A switching component is configured for switching the display of the local user interface between the front panel and the rear panel.

Abstract: A system and method which may be implemented at least partly by a computer, are provided for developing a support system. A virtual representation of a device is generated for display on a user interface. Links between components of the virtual representation, which represent components of the device, and corresponding cases in a searchable knowledge base (SKB) are stored. Users can navigate the SKB in search of a solution to a problem with the device with the assistance of the virtual representation which enables actuation of the existing links. The users are able to create new links, each new link linking a component of the virtual representation with a case in the SKB which the user identifies as providing a solution to the problem with the device which is related to the component. The new link is stored for future use by the user or by other users.

Abstract: A system for displaying feeds contents of a contact and for processing feeds contents of a contact. The system obtains feeds content data of a contact of a user, mixes and sorts the feeds content data. The system pulls out, when the user requests for obtaining the feeds contents of the contact, complete information of the feeds contents requested by the user, and displaying the complete information.
