In one example, a method performed by a processing system including at least one processor includes creating a geospatial model of an environment in which a cellular network is to be deployed, transforming, for each cellular antenna of a proposed antenna layout of the cellular network, a radiation pattern of the each cellular antenna into a signal strength array, to create a plurality of signal strength arrays, augmenting, for each signal strength array of the plurality of signal strength arrays, the each signal strength array with at least one parameter of a corresponding cellular antenna of the proposed antenna layout and at least one value describing the environment in which the cellular network is to be deployed, and estimating a coverage of the proposed antenna layout based on the signal strength array, as augmented, using a machine learning model.

Machine-learning-based wireless planning using antenna radiation patterns

A system for dynamic derivation of and sending to a contact group. The system may recognize an emergency situation (natural disaster, stranded, lost cell connection) and send a confirmation that may be sent to different contact groups from a network entity. The system may also recognize anomalous user behaviors and send a message indicating the anomalous user behaviors to different contact groups from the network entity.

Dynamic derivation of and broadcast to emergency contact list

A system for dynamic derivation of and sending to a contact group. The system may recognize an emergency situation (natural disaster, stranded, lost cell connection) and send a confirmation that may be sent to different contact groups from a network entity.

A method of increasing resolution of an image includes generating vector contours associated with a first image and scaling the vector contours to a second resolution. The first image has a first resolution, and the second resolution is greater than the first resolution. The vector contours are rendered to generate a guiding image at the second resolution, and a second image is generated from the first image based on the guiding image, by using joint upsampling. The second image is generated at the second resolution. The vector contours can be generated by bitmap tracing binary images at different quantization levels. An apparatus and computer readable device implementing the method of increasing the resolution of an image are also provided.

Guided image upsampling using bitmap tracing

A method includes receiving an image having a first resolution and generating an upsampled image having a second resolution based on the image. A multi-dimensional data structure corresponding to a multi-dimensional image space is generated from the upsampled image. Each node of the data structure is determined based on a weighted sum of values of one or more pixels in the upsampled image. Each of the one or more pixels corresponds to a pixel in the received image and is located within a region of the image space having a vertex defined by the node. A filter modifies the values of the nodes and a second upsampled image is generated based on the modified values. Each pixel of the second upsampled image not corresponding to a pixel in the received image is determined based on a weighted sum of the modified values of one or more nodes.
